TECHNICAL FIELD

The present disclosure relates to substituted tetrazole compounds, its derivatives, salts, stereo-isomers or regio-isomers thereof, which are useful as intermediates in the preparation of herbicidal sulfonamide or sulfonyl urea growth regulators or herbicides.

The present disclosure also relates to methods for the preparation of such intermediates.

BACKGROUND

Sulfonamide or sulfonyl urea growth regulators or herbicides are a more recent class of chemical compounds that function by inhibiting the action of a plant enzyme, stopping plant growth, and eventually killing the plant. These are well known as being highly beneficial for controlling undesirable vegetation in agronomically desirable crops.

The sulfonamide herbicides are reported to be prepared by various ways in the art. EP0204513 Bl, which is incorporated in its entirety by reference, describes the method for preparation of such sulfonylureas and sulfonylthioureas herbicide from sulfonyl isocyanate or isocyanate intermediates with an appropriate heterocyclic amines.The patent document further discloses the preparation of the sulfonyl isocyanate intermediates by reacting appropriate sulfonamide with phosgene in presence of n-butyl isocyanate and 1,4-diazabicyclo[2.2.2]octane. Further, sulfonyl thioisocyanates are reported to be prepared by reacting corresponding sulfonamides with carbon disulphide and potassium hydroxide to form dipotassium salt which on treatment with phosgene provides the isothiocyanate intermediates.

The patent US4650892 discloses a process of preparation of sulfonamide herbicides using aromatic sulfonyl chlorides and sulfonamides.

One type of sulfonamide herbicides is Azimsulfuron or N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-1-methyl-4-(2-methyl-2H-tetrazol-5-yl)-1 H-pyrazole-5-sulfonamide , which is well known and has been found to be particularly useful as post emergent herbicides when used against sensitive weeds. Azimsulfuron affects sensitive weeds through inhibition of the enzyme acetolactate synthase (ALS).

In view of the importance of the emerging sulfonamide or sulfonyl urea growth regulators or herbicides, there remains a need for developing new intermediates and viable processes for their synthesis that can be successfully used in the preparation of these herbicidal compounds

DETAILED DESCRIPTION

Definitions

In the structural formula given herein and throughout the present disclosure, the following terms have the indicated meaning, unless specifically stated otherwise.

The term "optionally substituted" as used herein means that the group in question is either unsubstituted or substituted with one or more of the substituents specified. When the group in question is substituted with more than one substituent, the substituent may be same or different.

"Halo" or "Halogen", alone or in combination with any other term means halogens such as chloro (CI), bromo (Br), fluoro (F) and iodo (I).

The term "Ci_7 alkyl" refers to a monoradical branched or unbranched saturated hydrocarbon chain having 1, 2, 3, 4, 5, 6 or 7 carbon atoms. This term is exemplified by groups such as methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, t-butyl, n-hexyl, n-heptyl, and the like which optionally carries one or more substituents, preferably one to two, each independently selected from CI, Br, F, I, NO2, CN, C1-5 alkyl, phenyl or a C1-C4 alkoxy.

The term " C6-Q4 aryl" refers to an aromatic carbocyclic group of 6 to 14 carbon atoms having a single ring (e.g. phenyl) or multiple rings (e.g. biphenyl), or multiple condensed (fused) rings (e.g. naphthyl or anthranyl). Preferred aryls include phenyl, naphthyl and the like which optionally carries one or more substituents, preferably one to two, each independently selected from CI, Br, F, I, Ci_5 alkyl, phenyl or a C1-C4 alkoxy.

The compounds described herein may contain one or more chiral centers and/or double bonds and therefore, may exist as stereo-isomers, such as geometric isomers, enantiomers or diastereomers. Accordingly, the chemical structures depicted herein encompass all possible enantiomers and stereo-isomers of the illustrated or identified compounds including the stereoisomerically pure form (e.g., geometrically pure, enantiomerically pure or diastereomerically pure) and enantiomeric and stereoisomeric mixtures. Enantiomeric and stereoisomeric mixtures can be resolved into their component enantiomers or stereo-isomers using separation techniques or chiral synthesis techniques well known to the person skilled in the art. The compounds may also exist in several tautomeric forms including the enol form, the keto form and mixtures thereof. Accordingly, the chemical structures depicted herein encompass all possible tautomeric forms of the illustrated or identified compounds.

The present disclosure will be described more fully hereinafter. Indeed, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. As used in the specification, and in the appended claims, the singular forms "a", "an", "the", include plural referents unless the context clearly dictates otherwise.
