FIELD The present invention relates to compounds effective in inhibiting replication of Hepatitis C virus ("HCV")- The present invention also relates to compositions comprising these compounds and methods of using these compounds to treat HCV infection. BACKGROUND HCV is an RNA virus belonging to the Hepacivirus genus in the Flaviviridae family. The enveloped HCV virion contains a positive stranded RNA genome encoding all known virus-specific proteins in a single, uninterrupted, open reading frame. The open reading frame comprises approximately 9500 nucleotides and encodes a single large polyprotein of about 3000 amino acids. The polyprotein comprises a core protein, envelope proteins E1 and E2, a membrane bound protein p7, and the non-structural proteins NS2, NS3, NS4A, NS4B, NS5A and NS5B. HCV infection is associated with progressive liver pathology, including cirrhosis and hepatocellular carcinoma. Chronic hepatitis C may be treated with peginterferon-alpha in combination with ribavirin. Substantial limitations to efficacy and tolerability remain as many users suffer from side effects, and viral elimination from the body is often inadequate. Therefore, there is a need for new drugs to treat HCV infection. SUMMARY The present invention features compounds of Formulae L IA, IB, Ic and ID, and pharmaceutically acceptable salts thereof.

The compounds of the present invention can be used in the form of salts. Depending on the particular compound, a salt of a compound may be advantageous due to one or more of the salt's physical properties, such as enhanced pharmaceutical stability under certain conditions or desired solubility in water or oil. In some instances, a salt of a compound may be useful for the isolation or purification of the compound. Where a salt is intended to be administered to a patient, the salt preferably is pharmaceutically acceptable. Pharmaceutically acceptable salts include, but are not limited to, acid addition salts, base addition salts, and alkali metal salts. Pharmaceutically acceptable acid addition salts may be prepared from inorganic or organic acids. Examples of suitable inorganic acids include, but are not limited to, hydrochloric, hydrobromic, hydroionic, nitric, carbonic, sulfuric, and phosphoric acid. Examples of suitable organic acids include, but are not limited to, aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclyl, carboxylic, and sulfonic classes of organic acids. Specific examples of suitable organic acids include acetate, trifluoroacetate, formate, propionate, succinate, glycolate, gluconate, digluconate, lactate, malate, tartaric acid, citrate, ascorbate, glucuronate, maleate, fumarate, pyruvate, aspartate, glutamate, benzoate, anthranilic acid, mesylate, stearate, salicylate, p-hydroxybenzoate, phenylacetate, mandelate, embonate (pamoate), methanesulfonate, ethanesulfonate, benzenesulfonate, pantothenate, toluenesulfonate, 2-hydroxyethanesulfonate, sufanilate, cyclohexylaminosulfonate, algenic acid, b-hydroxybutyric acid, galactarate, galacturonate, adipate, alginate, bisulfate, butyrate, camphorate, camphorsulfonate, cyclopentanepropionate, dodecylsulfate, glycoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, nicotinate, 2-naphthalesulfonate, oxalate, palmoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, thiocyanate, tosylate, and undecanoate. Pharmaceutically acceptable base addition salts include, but are not limited to, metallic salts and organic salts. Non-limiting examples of suitable metallic salts include alkali metal (group la) salts, alkaline earth metal (group Ha) salts, and other pharmaceutically acceptable metal salts. Such salts may be made, without limitation, from aluminum, calcium, lithium, magnesium, potassium, sodium, or zinc. Non-limiting examples of suitable organic salts can be made from tertiary amines and quaternary amine, such as tromethamine, diethylamine, N,N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine), and procaine. Basic nitrogen-containing groups can be quaternized with agents such as alkyl halides (e.g., methyl, ethyl, propyl, butyl, decyl, lauryl, myristyl, and stearyl chlorides/bromides/iodides), dialkyl sulfates (e.g., dimethyl, diethyl, dibuytl, and diamyl sulfates), aralkyl halides (e.g., benzyl and phenethyl bromides), and others. The compounds or salts of the present invention may exist in the form of solvates, such as with water (i.e., hydrates), or with organic solvents (e.g., with methanol, ethanol or acetonitrile to form, respectively, methanolate, ethanolate or acetonitrilate). The compounds or salts of the present invention may also be used in the form of prodrugs. Some prodrugs are aliphatic or aromatic esters derived from acidic groups on the compounds of the invention. Others are aliphatic or aromatic esters of hydroxyl or amino groups on the compounds of the invention. Phosphate prodrugs of hydroxyl groups are preferred prodrugs. The compounds of the invention may comprise asymmetrically substituted carbon atoms known as chiral centers. These compounds may exist, without limitation, as single stereoisomers (e.g., single enantiomers or single diastereomer), mixtures of stereoisomers (e.g. a mixture of enantiomers or diastereomers), or racemic mixtures. Compounds identified herein as single stereoisomers are meant to describe compounds that are present in a form that is substantially free from other stereoisomers (e.g., substantially free from other enantiomers or diastereomers). By "substantially free," it means that at least 80% of the compound in a composition is the described stereoisomer; preferably, at least 90% of the compound in a composition is the described stereoisomer; and more preferably, at least 95%, 96%, 97%, 98% or 99% of the compound in a composition is the described stereoisomer. Where the stereochemistry of a chiral carbon is not specified in the chemical structure of a compound, the chemical structure is intended to encompass compounds containing either stereoisomer of the chiral center. Individual stereoisomers of the compounds of this invention can be prepared using a variety of methods known in the art. These methods include, but are not limited to, stereospecific synthesis, chromatographic separation of diastereomers, chromatographic resolution of enantiomers, conversion of enantiomers in an enantiomeric mixture to diastereomers followed by chromatographically separation of the diastereomers and regeneration of the individual enantiomers, and enzymatic resolution. Stereospecific synthesis typically involves the use of appropriate optically pure (enantiomerically pure) or substantial optically pure materials and synthetic reactions that do not cause racemization or inversion of stereochemistry at the chiral centers. Mixtures of stereoisomers of compounds, including racemic mixtures, resulting from a synthetic reaction may be separated, for example, by chromatographic techniques as appreciated by those of ordinary skill in the art. Chromatographic resolution of enantiomers can be accomplished by using chiral chromatography resins, many of which are commercially available. In a non-limiting example, racemate is placed in solution and loaded onto the column containing a chiral stationary phase. Enantiomers can then be separated by HPLC. Resolution of enantiomers can also be accomplished by converting enantiomers in a mixture to diastereomers by reaction with chiral auxiliaries. The resulting diastereomers can be separated by column chromatography or crystallization/re-crystallization. This technique is useful when the compounds to be separated contain a carboxyl, amino or hydroxyl group that will form a salt or covalent bond with the chiral auxiliary. Non-limiting examples of suitable chiral auxiliaries include chirally pure amino acids, organic carboxylic acids or organosulfonic acids. Once the diastereomers are separated by chromatography, the individual enantiomers can be regenerated. Frequently, the chiral auxiliary can be recovered and used again. Enzymes, such as esterases, phosphatases or lipases, can be useful for the resolution of derivatives of enantiomers in an enantiomeric mixture. For example, an ester derivative of a carboxyl group in the compounds to be separated can be treated with an enzyme which selectively hydrolyzes only one of the enantiomers in the mixture. The resulting enantiomerically pure acid can then be separated from the unhydrolyzed ester. Alternatively, salts of enantiomers in a mixture can be prepared using any suitable method known in the art, including treatment of the carboxylic acid with a suitable optically pure base such as alkaloids or phenethylamine, followed by precipitation or crystalUzation/re-crystallization of the enantiomerically pure salts. Methods suitable for the resolution/separation of a mixture of stereoisomers, including racemic mixtures, can be found in ENANTIOMERS, RACEMATES, AND RESOLUTIONS (Jacques et al., 1981, John Wiley and Sons, New York, NY). A compound of this invention may possess one or more unsaturated carbon-carbon double bonds. All double bond isomers, such as the cis (Z) and trans (E) isomers, and mixtures thereof are intended to be encompassed within the scope of a recited compound unless otherwise specified. In addition, where a compound exists in various tautomeric forms, a recited compound is not limited to any one specific tautomer, but rather is intended to encompass all tautomeric forms. Certain compounds of the invention may exist in different stable conformational forms which may be separable. Torsional asymmetry due to restricted rotations about an asymmetric single bond, for example because of steric hindrance or ring strain, may permit separation of different confonners. The invention encompasses each conformational isomer of these compounds and mixtures thereof. Certain compounds of the invention may also exist in zwitterionic form and the invention encompasses each zwitterionic form of these compounds and mixtures thereof. The compounds of the present invention are generally described herein using standard nomenclature. For a recited compound having asymmetric center(s), it should be understood that all of the stereoisomers of the compound and mixtures thereof are encompassed in the present invention unless otherwise specified. Non-limiting examples of stereoisomers include enantiomers, diastereomers, and cis-transisomers. Where a recited compound exists in various tautomeric forms, the compound is intended to encompass all tautomeric forms. Certain compounds are described herein using general formulas that include variables (e.g., A, B, D, X, Li, L2, L3, Y, Z, T, RA or RB,). Unless otherwise specified, each variable within such a formula is defined independendy of any other variable, and any variable that occurs more than one time in a formula is defined independendy at each occurrence. If moieties are described as being "independently" selected from a group, each moiety is selected independently from the other. Each moiety therefore can be identical to or different from the other moiety or moieties. The number of carbon atoms in a hydrocarbyl moiety can be indicated by the prefix "Cx-Cy," where x is the minimum and y is the maximum number of carbon atoms in the moiety. Thus, for example, "C1-Cealkyl" refers to an alkyl substituent containing from 1 to 6 carbon atoms. Illustrating further, C3-C6cycloalkyl means a saturated hydrocarbyl ring containing from 3 to 6 carbon ring atoms. A prefix attached to a multiple-component substituent only applies to the first component that immediately follows the prefix. To illustrate, the term "carbocyclylalkyl" contains two components: carbocyclyl and alkyl. Thus, for example, C3-C6carbocyclylC1-C6alkyl refers to a C3-C6carbocyclyl appended to the parent molecular moiety through a C1-Cealkyl group. Unless otherwise specified, when a linking element links two other elements in a depicted chemical structure, the leftmost-described component of the linking element is bound to the left element in the depicted structure, and the rightmost-described component of the linking element is bound to the right element in the depicted structure. To illustrate, if the chemical structure is —L5—M— Ls'- and M is -N(RB)S(O)-, then the chemical structure is -Ls-N(RB)S(O)-Ls'-. If a linking element in a depicted structure is a bond, then the element left to the linking element is joined direcdy to the element right to the linking element via a covalent bond. For example, if a chemical structure is depicted as -Ls-M-Ls'- and M is selected as bond, then the chemical structure will be -Ls-Ls'-. If two or more adjacent linking elements in a depicted structure are bonds, then the element left to these linking elements is joined direcdy to the element right to these linking elements via a covalent bond. For instance, if a chemical structure is depicted as -Ls- M-Ls'-M'-Ls"-, and M and Lg' are selected as bonds, then the chemical structure will be -Lj-M'- Ls"-. Likewise, if a chemical structure is depicted as -Ls-M-Ls'-M'-Ls"-, and M, Ls' and M' are bonds, then the chemical structure will be -Ls-Ls"-. When a chemical formula is used to describe a moiety, the dash(s) indicates the portion of the moiety that has the free valence(s). If a moiety is described as being "optionally substituted", the moiety may be either substituted or unsubstituted. If a moiety is described as being optionally substituted with up to a particular number of non-hydrogen radicals, that moiety may be either unsubstituted, or substituted by up to that particular number of non-hydrogen radicals or by up to the maximum number of substitutable positions on the moiety, whichever is less. Thus, for example, if a moiety is described as a heterocycle optionally substituted with up to three non-hydrogen radicals, then any heterocycle with less than three substitutable positions will be optionally substituted by up to only as many non- hydrogen radicals as the heterocycle has substitutable positions. To illustrate, tetrazolyl (which has only one substitutable position) will be optionally substituted with up to one non-hydrogen radical. To illustrate further, if an amino nitrogen is described as being optionally substituted with up to two non-hydrogen radicals, then a primary amino nitrogen will be optionally substituted with up to two non-hydrogen radicals, whereas a secondary amino nitrogen will be optionally substituted with up to only one non-hydrogen radical. The term "alkenyl" means a straight or branched hydrocarbyl chain containing one or more double bonds. Each carbon-carbon double bond may have either cis or trans geometry within the alkenyl moiety, relative to groups substituted on the double bond carbons. Non-limiting examples of alkenyl groups include ethenyl (vinyl), 2-propenyl, 3-propenyl, 1,4-pentadienyl, 1,4-butadienyl, 1-butenyl, 2-butenyl, and 3-butenyl. The term "alkenylene" refers to a divalent unsaturated hydrocarbyl chain which may be linear or branched and which has at least one carbon-carbon double bond. Non-limiting examples of alkenylene groups include -C(H)=C(H)-, -C(H)=C(H)-CH2-, -C(H)=C(H)-CH2-CH2-, -€H2-C(H)=C(H)-CH2- -C(H)=C(H)-CH(CH3>-, and-CH2-C(H)=C(H)-CH(CH2CH3)-.

Non-limiting examples of alkynyl include ethynyl, 1-propynyl, 2-propynyl, 3-propynyl, decynyl, 1-butynyl, 2-butynyl, and 3-butynyl. The term "alkynylene" refers to a divalent unsaturated hydrocarbon group which may be linear or branched and which has at least one carbon-carbon triple bonds. Representative alkynylene groups include, by way of example, —GO-, —OO-CH2—, —OO-CH2—OH2—, -CH2-0O-CH2- -0O-CH(CH3)-, and-CH2-OC-CH(CH2CH3)-. The term "carbocycle" or "carbocyclic" or "carbocyclyl" refers to a saturated (e.g., "cycloalkyl"), partially saturated (e.g., "cycloalkenyl" or "cycloalkynyl") or completely unsaturated (e.g., "aryl") ring system containing zero heteroatom ring atom. "Ring atoms" or "ring members" are the atoms bound together to form the ring or rings. A carbocyclyl may be, without limitation, a single ring, two fused rings, or bridged or spiro rings. A substituted carbocyclyl may have either cis or trans geometry. Representative examples of carbocyclyl groups include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, cyclopentenyl, cyclopentadienyl, cyclohexadienyl, adamantyl, decahydro-naphthalenyl, octahydro-indenyl, cyclohexenyl, phenyl, naphthyl, indanyl, 1,2,3,4-tetrahydro-naphmyl, indenyl, isoindenyl, decalinyl, and norpinanyl. A carbocycle group can be attached to the parent molecular moiety through any substitutable carbon ring atom. Where a carbocycle group is a divalent moiety linking two other elements in a depicted chemical structure (such as A in Formula I), the carbocycle group can be attached to the two other elements through any two substitutable ring atoms. Likewise, where a carbocycle group is a trivalent moiety linking three other elements in a depicted chemical structure (such as X in Formula T), the carbocycle group can be attached to the three other elements through any three substitutable ring atoms, respectively. The term "carbocyclylalkyl" refers to a carbocyclyl group appended to the parent molecular moiety through an alkylene group. For instance, C3-C6carbocyclylC1-C6alkyl refers to a C3- Qcarbocyclyl group appended to the parent molecular moiety through Cx-Qalkylene. The term "cycloalkenyl" refers to a non-aromatic, partially unsaturated carbocyclyl moiety having zero heteroatom ring member. Representative examples of cycloalkenyl groups include, but are not limited to, cyclobutenyl, cyclopentenyl, cyclohexenyl, and octahydronaphthalenyl. The term "cycloalkyl" refers to a saturated carbocyclyl group containing zero heteroatom ring member. Non-limiting examples of cycloalkyls include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, decalinyl and norpinanyl. The prefix "halo" indicates that the substituent to which the prefix is attached is substituted with one or more independently selected halogen radicals. For example, "C1-Cehaloalkyl" means a C1-Cgalkyl substituent wherein one or more hydrogen atoms are replaced with independently selected halogen radicals. Non-limiting examples of C1-Cehaloalkyl include chloromethyl, 1-bromoethyl, fiuoromethyl, difluoromethyl, trifluoromethyl, and 1,1,1-trifluoroethyl. It should be recognized that if a substituent is substituted by more than one halogen radical, those halogen radicals may be identical or different (unless otherwise stated). The term "heterocycle" or "heterocyclo" or "heterocyclyl" refers to a saturated (e.g., "heterocycloalkyl"), partially unsaturated (e.g., "heterocycloalkenyl" or "heterocycloalkynyl") or completely unsaturated (e.g., "heteroaryl") ring system where at least one of the ring atoms is a heteroatom (i.e., nitrogen, oxygen or sulfur), with the remaining ring atoms being independently selected from the group consisting of carbon, nitrogen, oxygen and sulfur. A heterocycle may be, without limitation, a single ring, two fused rings, or bridged or spiro rings. A heterocycle group can be linked to the parent molecular moiety via any substitutable carbon or nitrogen atom(s) in the group. Where a heterocycle group is a divalent moiety that links two other elements in a depicted chemical structure (such as A in Formula I), the heterocycle group can be attached to the two other elements through any two substitutable ring atoms. Likewise, where a heterocycle group is a trivalent moiety that links three other elements in a depicted chemical structure (such as X in Formula I), the heterocycle group can be attached to the three other elements through any three substitutable ring atoms, respectively.

The term "prodrug" refers to derivatives of the compounds of the invention which have chemically or metabolically cleavable groups and become, by solvolysis or under physiological conditions, the compounds of the invention which are pharmaceutically active in vivo. A prodrug of a compound may be formed in a conventional manner by reaction of a functional group of the compound (such as an amino, hydroxy or carboxy group). Prodrugs often offer advantages of solubility, tissue compatibility, or delayed release in mammals (see, Bungard, H., DESIGN OF PRODRUGS, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acidic compound with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a suitable amine. Examples of prodrugs include, but are not limited to, acetate, formate, benzoate or other acylated derivatives of alcohol or amine functional groups within the compounds of the invention. The term "solvate" refers to the physical association of a compound of this invention with one or more solvent molecules, whether organic or inorganic. This physical association often includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. "Solvate" encompasses both solution-phase and isolable solvates. Exemplary solvates include, but are not limited to, hydrates, ethanolates, and methanolates. The term "N-protecting group" or "N-protected" refers to those groups capable of protecting an amino group against undesirable reactions. Commonly used N-protecting groups are described in Greene and Wuts, PROTECTING GROUPS IN CHEMICAL SYNTHESIS (3rd ed., John Wiley & Sons, NY (1999). Non-limiting examples of N-protecting groups include acyl groups such as formyl, acetyl, propionyl, pivaloyl, t-butylacetyl, 2-chloroacetyl, 2-bromoacetyl, trifluoroacetyl, trichloroacetyl, phthalyl, o-nitrophenoxyacetyl, benzoyl, 4-chlorobenzoyl, 4-bromobenzoyl, or 4-nitrobenzoyl; sulfonyl groups such as benzenesulfonyl or p-toluenesulfonyl; sulfenyl groups such as phenylsulfenyl (phenyl-S-) or triphenylmethylsulfenyl (trityl-S-); sulfinyl groups such as p-methylphenylsulfinyl (p- methylphenyl-S(O)-) or t-butylsulfinyl (t-Bu-S(O)-); carbamate forming groups such as benzyloxycarbonyl, p-chlorobenzyloxycarbonyl, p-methoxybenzyloxycarbonyl, p- nitrobenzyloxycarbonyl, 2-nitrobenzyloxycarbonyl, p-bromobenzyloxycarbonyl, 3,4- dimethoxybenzyloxycarbonyl, 3,5 -dimethoxybenzyloxycarbonyl, 2,4-dimethoxybenzyloxycarbonyl, 4-methoxybenzyloxycarbonyl, 2-nitro-4,5 -dimethoxybenzyloxycarbonyl, 3,4,5- trimethoxybenzyloxycarbonyl, 1 -(p-biphenylyl)-1 -methylethoxycarbonyl, dimethyl-3,5- dimethoxybenzyloxycarbonyl, benzhydryloxycarbonyl, t-butyloxycarbonyl, diisopropylmemoxycarbonyl, isopropyloxycarbonyl, ethoxycarbonyl, methoxycarbonyl, allyloxycarbonyl, 2,2,2-trichloro-ethoxy-carbonyl, phenoxycarbonyl, 4-nitro-phenoxycarbonyl, cyclopentyloxycarbonyl, adamantyloxycarbonyl, cyclohexyloxycarbonyl, or phenylthiocarbonyl; alkyl groups such as benzyl, p-methoxybenzyl, triphenylmethyl, or benzyloxymethyl; p- methoxyphenyl; and silyl groups such as trimethylsilyl. Preferred N-protecting groups include formyl, acetyl, benzoyl, pivaloyl, t-butylacetyl, phenylsulfonyl, benzyl, t-butyloxycarbonyl (Boc) and benzyloxycarbonyl (Cbz). The compounds of the present invention can be prepared using a variety of methods. As a non-limiting example, the compounds of the present invention can be prepared according to Scheme I starting from compounds of Formula II (e.g., n = 0 to 8), Formula V (X4 can be, for example, O or NRA, where RA is as described hereinabove and is preferably H or RE as defined above such as Cl- C6alkyl, 3- to 12-membered carbocycle or heterocycle, -C(O)Rs, -C(O)ORs, -C(O)N(RsRs'), - SO2N(RsRs'), -S(O)20RS, -S(O)ORs, -S(O)N(RsRs'), or a suitable protecting group such as Boc or Fmoc), or Formula VTA (E can be, for example, 3- to 7-membered carbocycle or heterocycle and is optionally substituted with one or more RA), wherein A, B, D, Y, Z and RA are as described above. The 1,4-diketones IL V, and VET can be reduced to the 1,4-diols using the methods described below, and the resultant racemic, enantiomerically enriched, or meso 1,4-diols may be converted to the dimesylates HI, VI, or IX, or alternatively to ditriflates, ditosylates, or dihalides by the methods described below. The dimesylates HI, VI, and DC, ditriflates, ditosylates, or dihalides may be reacted with an amine, including but not limited to, aniline, 3,5-difluoroaniline, 3,4-difluoroaniline, 4- fluoroaniline, 3-fluoroaniline, 4-trifluoromethylaniline, 4-chloroaniline, heteroaryl amines, alkyl amines, cycloalkyl amines, substituted benzylamines, or allylamine, under the conditions described below to give the compounds of the invention. Li and La can be readily introduced to Formulae IL V and VHI, as appreciated by those skilled in the art in light of the present invention. Likewise, D-L3- NH2 can be used instead of D-NH2, as appreciated by those skilled in the art. As another non-limiting example, the compounds of the present invention can be prepared starting from compounds of Formula II and Formula III as shown in Scheme n. The 1,4-diketones such as Formula IV may be prepared using known methods (see Nevar, et al., Synthesis: 1259-1262 (2000), such as the reaction of cx-bromoketones such as Formula II with methyl ketones such as Formula HI in the presence of a suitable Lewis acid such as ZnCl2 or Ti(0iPr)4. The 1,4-diketones IV may be reduced to the 1,4-diols such as V by the action of NaBIL,, LLAIH4, or DIBAL. Alternatively, enantioselective reduction of 1,4-diketones such as Formula IV can be accomplished by analogy with reported methods (see Chong, et al., Tetrahedron: Asymmetry 6:409-418 (1995), Li, et al., Tetrahedron 63:8046-8053 (2007), Aldous, et al., Tetrahedron: Asymmetry 11:2455-2462 (2000), Masui, et al., Synlett:273-274 (1997), Jing, et al., Adv. Synth. Catal. 347:1193-1197 (2005), Sato, et al., Synthesis:1434-1438 (2004)), such as reduction with (-) or (+)-diisopinocamheylchloroborane (DIP-chloride), with borane and an oxazaborolidine catalyst, or with asymmetric hydrogenation in the presence of a suitable Ruthenium (II) catalyst, such as [RuC12{(R)-BINAP}{(R,R)-DPEN}] (BINAP=2,2' -bis(diarylphosphino)-1,1' -binaphthyl; DPEN= 1,2-diphenylethylenediamine). The resultant racemic, enantiomerically enriched, or meso 1,4-diols V may be reacted with methanesulfonyl chloride to provide the dimesylate Formula VL Alternatively Formula V may be converted to a ditriflate or ditosylate by the action of p-toluenesulfonyl chloride or triflic anhydride, or to a dihalide such as a dibromide or dichloride by the action of PPh3 in the presence of CC14 or CBr4, or by the action of SOCl2, POCl3, or PBr3. The dimesylate, ditriflate, ditosylate, or dihalide may be reacted with an amine, such as 4-fluoroaniline (as shown for illustration in Scheme H), with or without a co-solvent such as DMF at room temperature to 100 °C, to give the pyrrolidines such as Formula VII. In addition to 4-fluoroaniline, alternative amines may be reacted with the dimesylate Formula VI, including but not limited to aniline, 3,5-difluoroaniline, 3,4-difluoroaniline, 3- fluoroaniline, 4-trifluoromethylaniline, 4-chloroaniline, heteroaryl amines, alkyl amines, cycloalkyl amines, substituted benzylamines, or allylamine. The dinitro Formula VII may be reduced to the diamino Formula Vm using Fe in the presence of NH4CI, HC1, or acetic acid, or by treatment with a hydride reducing agent, such as sodium borohydride (with or without the addition of a transition metal salt, such as BiCl3, SbCl3, NiCl2, Cu2Cl2, or CoCl2) in a solvent such as ethanol or THF. Alternatively, Formula VII can be reduced to the product Formula VTA by hydrogenation in the presence of a suitable catalyst, such as a palladium or platinum catalyst or Raney nickel. The diamine Formula VIE may be reacted with a suitably protected proline acid (Boc is shown, although Cbz, Troc, or Fmoc may be substituted) in the presence of a peptide coupling reagent, such as EDAC/HOBT, PyBOP, HATU, or DEBPT, in a solvent such as THF, DMF, dichloromethane, or DMSO, with or without the addition of an amine base such as Hunig's base, pyridine, 2,6-lutidine, or triemylarnine, to give Formula IX. Removal of the Boc protecting groups to give X may be accomplished by treatment with an acid, such as TFA, HC1, or formic acid. Compounds of the present invention may be prepared by coupling of Formula X with an acid of choice using the standard peptide coupling reagents and conditions described above. Alternately, diamine VIII may be reacted with an N-substituted proline in the presence of a peptide coupling reagent such as EDAC/HOBT, PyBOP, HATU, T3P, or DEBPT, in a solvent such as THF, DMF, dichloromethane, or DMSO, with or without the addition of an amine base such as Hunig's base, pyridine, 2,6-lutidine, or triethylamine, to directly give compounds of the present invention (Formula XT). in each Formula within Scheme II can be replaced with where D is defined above, and such compounds can be readily prepared according to the process described in Scheme II (including making compound XI directly from compound VTH). As yet another non-limiting example, the compounds of the present invention can be prepared starting from compounds of Formula II and Formula HI as shown in Scheme HI, where A, B, D, Y, and Z are as described above, using conditions similar to those described above for the preparation of IV in Scheme II. Similarly, the resulting 1,4-diketone IV may be reduced to the 1,4-diols V using the methods described above for Scheme II. The resultant racemic, enantiomerically enriched, or meso 1,4-diols V may be converted to the dimesylate VI or alternatively to a ditriflate, ditosylate, or dihalide by the methods described above. The dimesylate VI, ditriflate, ditosylate, or dihalide may be reacted with an amine, including but not limited to, aniline, 3,5-difluoroaniline, 3,4-difluoroaniline, 4- fluoroaniline, 3-fluoroaniline, 4-trifluoromethylaniline, 4-chloroaniline, heteroaryl amines, alkyl amines, cycloalkyl amines, substituted benzylamines, or allylamine, under the conditions described above the give die compounds of the invention. Alternatively, compounds such as VIII, where R is a group such as allyl, 4-methoxybenzyl, or 2,4-dimethoxybenzyl, may be treated with reagents useful for the removal of the R group (rhodium catalyst such as Rh(Ph3P)3Cl for R = allyl, treatment with an acid such as TFA or HC1 for R = 4-methoxybenzyl or 2,4-dimethoxybenzyl, hydrogenolysis with a Pd catalyst for R = substituted benzyl) to generate compounds such as IX. Amine K may be reacted with an aryl halide or triflate such as X (iodide shown for illustration) employing the Buchwald- Hartwig reaction in the presence of a palladium catalyst (such as Pd(OAc)2 or Pd2(dba)3) and a phosphine ligand (such as triphenylphosphine or XantPhos) and a base (such as sodium bis(trimethylsilyl)amide, potassium tert-butoxide, or K3P04) to give the compounds of the present invention. Alternatively, the compounds of the present invention may be obtained by reaction of K with an aldehyde or ketone through reductive amination in the presence of a hydride reducing agent, such as sodium borohydride or sodium cyanoborohydride (with or without the addition of an acid, such as acetic acid) in a solvent such as ethanol, toluene, THF, or dichloromethane. Alternatively the reductive amination may be conducted through the use of hydrogenation in the presence of a suitable catalyst, such as a palladium or platinum catalyst or Raney nickel. Alternatively, amine IX may react with electrophilic reagents, such as alkyl halides, or with aryl electrophiles (suitably electron deficient aryl and heteroaryl halides and triflates) through nucleophilic aromatic substitution reactions to give the compounds of the present invention. amines, cycloalkyl amines, substituted benzylamines, or allylamine to give VIL When X5 in Formula VII is nitro, the nitro groups may be reduced to the tetraamino product IX using Fe in the presence of NH4CI, HC1, or acetic acid, or with a hydride reducing agent, such as sodium borohydride (with or without the addition of a transition metal salt, such as BiCU, SbCl3, NiCl2, Q12Q2, or CoCl2) in a solvent such as ethanol or THF. Alternatively, VII (X5 = nitro) can be reduced to the product IX by hydrogenation in the presence of a suitable catalyst, such as a palladium or platinum catalyst or Raney nickel. Alternatively, compounds VII where X5 = halogen may be reacted with ammonia (R = H) or an amine bearing a suitable protecting group (R = substituted benzyl such as 4-methoxybenzyl or 2,4 dimethoxybenzyl or R = allyl). The resulting products VIII may be treated with a reagent useful for the removal of the R protecting group (rhodium catalyst such as Rh(Ph3P)3Cl for R = allyl, treatment with an acid such as TFA or HC1 for R = 4-methoxybenzyl or 2,4-dimethoxybenzyl, hydrogenolysis with a Pd catalyst for R = substituted benzyl) to give the product IX. Formula IX may be reacted with a suitably protected proline acid (Boc is shown, although Cbz, Troc, or Fmoc may be substituted) in the presence of a peptide coupling reagent, such as EDAC/HOBT, PyBOP, HATU, or DEBPT, in a solvent such as THF, DMF, dichloromethane, or DMSO, with or without the addition of an amine base, such as Hunig's base, pyridine, 2,6-lutidine, or triethylamine, to give X as a mixture of the amide products. Conversion to the benzimidazole compound XI may be accomplished by heating X in acetic acid (5O-100 °C). Alternatively, XI may be prepared by reaction of IX with an aldehyde, followed by treatment with an oxidant, such as Cu(OAc)2 or Mn02 (see Penning, et al., Bioorg. Med. Chem. 16:6965-6975 (2008). After removal of the Boc protecting groups from XI (accomplished by treatment with an acid, such as TFA, HC1, or formic acid), the compounds of the present invention may be prepared by coupling of the resulting diamine XII with an acid of choice using the standard peptide coupling reagents and conditions described above for Scheme II. in each Formula within Scheme IV can be replaced with where D is defined above, and such compounds can be readily prepared according to the process described in Scheme TV. Alternatively IX in Scheme IV may be prepared from a compound of Formula II as shown in Scheme V. Compound VIU from Scheme II may be treated with an acylating agent such as acetyl chloride or acetic anhydride to give compound II (Scheme V). Nitration of compound II to provide III may be accomplished using known methods, such as treatment with nitric acid or potassium nitrate in the presence of an acid such as sulfuric acid or treatment with N02BF4. Removal of the acetamide protecting group may be accomplished by treatment with Boc anhydride in the presence of DMAP to give IV, followed by sequential treatment of IV with hydroxide (such as NaOH, KOH, or LiOH) to remove the acetyl group and a strong acid such as TFA or HC1 to remove the Boc protecting group. The nitro groups in V may be reduced to amino groups using the methods described above for Scheme IV. in each Formula within Scheme V can be replaced with where D is defined above, and such compounds can be readily prepared according to the process described in Scheme V. As still another non-limiting example, the compounds of the present invention can be prepared starting from compounds of Formula II as shown in Scheme VI, where A, B, D, Y, and Z are as described above. A 1,4-diketone compound of Formula II (prepared as described in Scheme III) may be reacted with an amine, including but not limited to, aniline, 3,5-difluoroaniline, 3,4- difluoroaniline, 4-fluoroaniline, 3-fluoroaniline, 4-trifluoromethylaniline, 4-chloroaniline, heteroaryl amines, alkyl amines, cycloalkyl amines, substituted benzylamines, or allylamine, under acid catalyzed conditions, such as acetic acid, TFA, formic acid or HC1, to give the compounds of the invention. As a further non-limiting example, the compounds of the present invention can be prepared from a compound of Formula II as shown in Scheme VH. A compound of Formula II, where Rx is a halogen, such as bromo, chloro, or iodo, or a triflate or a nonaflate may be converted to a boronic acid or ester such as Formula HI, where R is hydrogen, methyl, ethyl, or a cyclic pinacolate ester. For example a compound of Formula II can be transformed to a compound of HI by treatment with pinacol-borane in the presence of a catalyst such as, for example, tris(dibenzylidineacetone)palladium (O), and a ligand such as, for example, tri-t-butylphosphine, in solvents such as, for example, tetrahydrofuran, dioxane, or toluene at temperatures ranging from ambient to about 130°C. Alternatively, compound II can be reacted with bis(pinacolato)diboron in the presence of a catalyst such as, for example, Combiphos-Pd6 (CombiPhos Catalysts, Inc. (NJ, USA), dichloro[l,l'- bis(diphenylphosphino)ferrocene] palladium (H) dichloromethane adduct, or palladium acetate in the presence of a ligand such as, for example, 2-dicyclohexylphosphino-2',4',6'-triisopropylbiphenyl (XPhos), and a base such as, for example, potassium acetate in solvents such as, for example, toluene, dioxane, tetrahydrofuran, dimethylformamide or dimethyl sulfoxide at temperatures from about 60 to about 130°C to give compound HI Alternatively, a compound of Formula II may be reacted with an organolithium reagent, such an n-BuLi, sec-BuLi, or t-BuLi, followed by reaction with trimethyl borate or triethyl borate, to give a compound of Formula HI. A compound of Formula HI in Scheme VII can be coupled with a compound of Formula IV, where RY is a halogen, such as bromo, chloro or iodo, under Suzuki reaction conditions to provide a compound of Formula V. Such conditions include, for example, use of a palladium catalyst such as, for example, tris(dibenzylidineacetone)palladium (O), palladium acetate, bis(triphenylphosphine)palladium (H) chloride, tetrakis(triphenylphosphine)palladium, or dichloro[l,r-bis(diphenylphosphino)ferrocene] palladium (H) dichloromethane adduct; base such as, for example, potassium carbonate, potassium phosphate, potassium t-butoxide, sodium carbonate, cesium carbonate, or cesium fluoride; and solvent such as, for example, toluene, ethanol, water, or tetrahydrofuran, or mixtures ttiereof heated in the temperature range from about 40 to about 130°C. Removal of the Boc protecting groups from V may be accomplished by treatment with an acid, such as TFA, HC1, or formic acid. Compounds of the present invention such as VI may be prepared by coupling the resulting amino compounds with an acid of choice using the standard peptide coupling reagents, such as EDAC/HOBT, PyBOP, HATU, or DEBPT, in a solvent such as THF, DMF, dichloromethane, or DMSO, with or without the addition of an amine base such as Hunig's base, pyridine, 2,6-lutidine, or triethylamine. Each Rz is independently -LY'-M'-RD (e.g., - LY-N(RB")C(O)-LS-RE), and D, L3, Ri, R2, R5 , Ly, RB", Ls, RE , W, M' and RD are as defined above. As another non-limiting example, the compounds of the present invention can be prepared according to Scheme Vm starting from the compound of Formula E, initially cleaving the diol in oxidative fashion followed by subsequent acid hydrolysis of the acetonide. This dialdehyde intermediate is then treated with an aryl boronate or aryl boronic acid (compound IV where A and Y are as described previously, or compound VTf) and aniline III (where W is RM or J, and RM and J are as defined above) resulting in the formation of Formula V or Formula VIA respectively. Formula V can be derivatized by deprotonating the hydroxyl groups with a strong base such as sodium hydride, butyl lithium, or potassium hydride, followed by alkylation with Rs-halogen. Alternatively Formula VUI can be deprotonated with a strong base (e.g., sodium hydride) and alkylated with Rs-halogen as well, followed by acid hydrolysis of the phenol protecting groups. The sulfonylation of the phenols with nonafluorobutylsulfonyl fluoride in the presence of a neutralizing agent such as potassium carbonate in a polar aprotic solvent such as DMF, followed by heating provides a compound of Formula DC. Boronate of Formula X is produced by heating Formula IX with bis(pinacolato)diboron in the presence of X-phos and a palladium catalyst, such as Pd2(dba)3 and a base such as potassium acetate in an organic solvent such as dioxane. Formula X is further derivatized to final product by heating a suitably substituted heteroarylhalide in the presence of a palladium catalyst such as PdCl2(dppf) in the presence of a base such as sodium carbonate in a mixture of toluene and ethanol. Rs is as defined above. in each Formula within Scheme VHI can be replaced with where D is defined above, and such compounds can be readily prepared according to the process described in Scheme VITL As yet another non-limiting example, the compounds of the present invention can be prepared according to Scheme IX starting from the compounds of Formula II and Formula DL Formula m carboxylic acid is activated towards coupling using reagents such as isobutylchloroformate, DCC, EDAC, or HATU in the presence of an organic base, such as diisopropylethylamine. Upon activation, dianiline of Formula II is added to the reaction, with the isolation of an intermediate amide, which is heated in acetic acid, preferably at 60 °C, to yield the compound of Formula IV. The benzimidazole of Formula IV is treated with SEM-C1 in the presence of a base in an aprotic solvent such as THF, yielding two protected benzimidazole regioisomers V. The boronate esters VI are produced by heating Formula V with bis(pinacolato)diboron in the presence of a palladium catalyst, such as PdC12(dppf), X-Phos, and a base such as potassium acetate in an organic solvent such as dioxane. Heating yields both benzimidazole regioisomers VI. Diol VII is cleaved in oxidative fashion followed by subsequent acid hydrolysis of the acetonide. This dialdehyde intermediate is then treated with an aryl boronate VI and aniline VHI (where W is RM or J, and RM and J are as defined above) resulting in the formation of the 3 benzimidazole regioisomers of Formula IX. Formula X is produced by deprotonating the hydroxyl groups with a strong base such as sodium hydride, butyl lithium, or potassium hydride, followed by alkylation with Rs-halogen, followed by acid hydrolysis of the pyrollidine and benzimidazole protecting groups, preferably by treatment with mineral acid, such as hydrochloric acid in an alcoholic solvent such as methanol. The carboxylic acid Rz-COOH is activated towards coupling using reagents such as isobutylchloroformate, DCC, EDAC, or HATU in the presence of an organic base, such as diisopropylethylamine. Upon activation, Formula X is added to the reaction, with the isolation of Formula XI. in each Formula within Scheme IX can be replaced with where D is defined above, and such compounds can be readily prepared according to the process described in Scheme DC.

In addition, the following mixtures of stereoisomers were prepared according to procedures similar to those described above, where each compound in each stereoisomer mixture can be readily isolated using chiral chromatography or other suitable methods as appreciated by those skilled in the art and, therefore, the present invention also features each compound in these stereoisomer mixtures: mixture 24 When tested using HCV lb-Conl replicon assays in the presence of 5% FBS, each of the above mixtures (except mixture 12) showed an EC50 value of less than 1 nM. Mixture 12 showed an EC50 value of from about 1 to 10 nM in HCV lb-Conl replicon assays in the presence of 5% FBS. Likewise, the following compounds of Formula I or pharmaceutically acceptable salts thereof can be similarly prepared according to the schemes and procedures described above, wherein A is selected from Table 1a, B is selected from Table 1b, D is selected from Table 2, Y and Z are each independently selected from Table 3, and is selected from Table 4, and A, B, D and X are each independently optionally substituted with one or more RA, and wherein L1, L2, L3 and RA are as described above. Preferably, L1, L2 and L3 are bond. Each compound's anti-HCV activity can be determined by measuring the activity of the luciferase reporter gene in the replicon in the presence of 5% FBS. The luciferase reporter gene is placed under the translational control of the poliovirus IRES instead of the HCV IRES, and HuH-7 cells are used to support the replication of the replicon. The inhibitory activities of the compounds of the present invention can be evaluated using a variety of assays known in the art. For instance, two stable subgenomic replicon cell lines can be used for compound characterization in cell culture: one derived from genotype la-H77 and the other derived from genotype lb-Conl, obtained from University of Texas Medical Branch, Galveston, TX or Apath, LLC, St. Louis, MO, respectively. The replicon constructs can be bicistronic subgenomic replicons. The genotype la replicon construct contains NS3-NS5B coding region derived from the H77 strain of HCV (la-H77). The replicon also has a firefly luciferase reporter and a neomycin phosphotransferase (Neo) selectable marker. These two coding regions, separated by the FMDV 2a protease, comprise the first cistron of the bicistronic replicon construct, with the second cistron containing the NS3-NS5B coding region with addition of adaptive mutations E1202G, K1691R, K2040R and S2204I. The lb-Conl replicon construct is identical to the la-H77 replicon, except that the HCV 5' UTR, 3' UTR, and NS3-NS5B coding region are derived from the lb-Conl strain, and the adaptive mutations are K1609E, K1846T and Y3005C. In addition, the lb-Conl replicon construct contains a poliovirus IRES between the HCV IRES and the luciferase gene. Replicon cell lines can be maintained in Dulbecco's modified Eagles medium (DMEM) containing 10% (v/v) fetal bovine serum (FBS), 100 IU/ml penicillin, 100 mg/ml streptomycin (Invitrogen), and 200 mg/ml G418(lnvitrogen). The inhibitory effects of the compounds of the invention on HCV replication can be determined by measuring activity of the luciferase reporter gene. For example, replicon-containing cells can be seeded into 96 well plates at a density of 5000 cells per well in 100 ul DMEM containing 5% FBS. The following day compounds can be diluted in dimethyl sulfoxide (DMSO) to generate a 200x stock in a series of eight half-log dilutions. The dilution series can then be further diluted 10O-fold in the medium containing 5% FBS. Medium with the inhibitor is added to the overnight cell culture plates already containing 100 {jl of DMEM with 5% FBS. In assays measuring inhibitory activity in the presence of human plasma, the medium from the overnight cell culture plates can be replaced with DMEM containing 40% human plasma and 5% FBS. The cells can be incubated for three days in the tissue culture incubators after which time 30 μl of Passive Lysis buffer (Promega) can be added to each well, and then the plates are incubated for 15 minutes with rocking to lyse the cells. Luciferin solution (100 μl Promega) can be added to each well, and luciferase activity can be measured with a Victor II luminometer (Perkin-Elmer). The percent inhibition of HCV RNA replication can be calculated for each compound concentration and the EC50 value can be calculated using nonlinear regression curve fitting to the 4-parameter logistic equation and GraphPad Prism 4 software. Using the above-described assays or similar cell-based replicon assays, representative compounds of the present invention showed significantly inhibitory activities against HCV replication.
