TITLE: Novel oxadiazoles

FIELD OF THE INVENTION:

The present invention relates to novel oxadiazoles, their N-oxides, metal complexes, isomers, polymorphs and/or the agriculturally acceptable salts thereof and to a process for preparing the same. Further, the present invention relates to a combination and to compositions comprising novel oxadiazoles of the present invention. Still further, the present invention relates to the use of novel oxadiazoles for controlling or preventing phytopathogenic fungi and to a method for controlling or preventing harmful phytopathogenic fungi.

BACKGROUND:

Oxadiazoles have already been disclosed in the literature. For example in JP56065881, JP63162680, JPS6061573, JPS6296480, JPS6051188, JP2005336101, W02005051932, EP3165093, EP3165094, EP3167716, EP3165093, JP2017190296, US4488897, WO2015185485, WO2017055469,

WO2017055473, WO2017076739, W02017076740, W02017081311, W02017085098, W02017085100, W02017093019, WO2017093348, WO2017102006, W02017103219, WO2017103223, WO2017109044, W02017110861, WO2017110862, WO2017110863, WO2017110864, WO2017110865, WO2017111152, WO2017118689, WO2017148797, WO2017157962, WO2017162868, WO2017169893, WO2017174158, WO2017178245, WO2017178549, WO2017198852, WO2017207757, WO2017211649, W02017211650, WO2017211652, WO2017213252, WO2017220485, WO201772247, WO201776742,

WO201776757, WO201776935, W0201781309, W0201781310, WO201781311, WO201781312, WO2018015447, WO2018015449, WO2018015458, W02018056340, WO2018055135,

W02018080859, WO2018118781, WO2018117034, WO2018153730 and WO2018114393, various oxadiazoles have been disclosed.

The oxadiazoles reported in the above literature have disadvantages in certain aspects, such as that they exhibit a narrow spectrum of application, or they do not have satisfactory fungicidal activity, particularly at low application rates.

Therefore, it is an object of the present invention to provide compounds having an improved/enhanced activity and/or a broader activity spectrum against phytopathogenic fungi.

This objective is achieved by the use of novel oxadiazoles of the present invention for controlling or preventing phytopathogenic fungi.

SUMMARY:

The present invention relates to novel oxadiazoles of Formula I.

wherein, R1, A1, A2, A3, A4, A5, L1, A, L2 and R2 are as defined in the detailed description.

The compound of Formula I have now been found to have advantages over the compounds reported in the literature in either of improved fungicidal activity, broader spectrum biological activity, lower application rates, biological or environmental properties, and/or enhanced plant compatibility.

More specifically, the present invention further relates to combinations comprising novel oxadiazoles and at least one further pesticidally active substance for controlling or preventing phytopathogenic fungi which are difficult to control or prevent.

The present invention still further relates to compositions comprising novel oxadiazoles or novel oxadiazoles in combination with further pesticidally active substances.

The present invention still further relates to a method and use of novel oxadiazoles, of combinations or of compositions thereof for controlling and or preventing plant diseases, particularly phytopathogenic fungi.

DETAILED DESCRIPTION:

DEFINITIONS:

The definitions provided herein for the terminologies used in the present disclosure are for illustrative purpose only and in no manner limit the scope of the present invention disclosed in the present disclosure.

As used herein, the terms “comprises”, “comprising”, “includes”, “including”, “has”, “having”, “contains”, “containing”, “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method.

The transitional phrase “consisting of’ excludes any element, step or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of’ appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

The transitional phrase “consisting essentially of’ is used to define a composition or method that includes materials, steps, features, components or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of’ occupies a middle ground between “comprising” and “consisting of’.

Further, unless expressly stated to the contrary, “or” refers to an inclusive “or” and not to an exclusive “or”. For example, a condition A “or” B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

Also, the indefinite articles “a” and “an” preceding an element or component of the present invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.

The term “agronomic” refers to the production of field crops such as for food, feed and fiber and includes the growth of corn, soybeans and other legumes, rice, cereal (e.g., wheat, oats, barley, rye, rice, maize), leafy vegetables (e.g., lettuce, cabbage, and other cole crops), fruiting vegetables (e.g., tomatoes, pepper, eggplant, crucifers and cucurbits), potatoes, sweet potatoes, grapes, cotton, tree fruits (e.g., pome, stone and citrus), small fruit (berries, cherries) and other specialty crops (e.g., canola, sunflower, olives).

The term “nonagronomic” refers to other than field crops, such as horticultural crops (e.g., greenhouse, nursery or ornamental plants not grown in a field), residential, agricultural, commercial and industrial structures, turf (e.g., sod farm, pasture, golf course, lawn, sports field, etc.), wood products, stored product, agro-forestry and vegetation management.

Compounds of the present disclosure may be present either in pure form or as mixtures of different possible isomeric forms such as stereoisomers or constitutional isomers. The various stereoisomers include enantiomers, diastereomers, chiral isomers, atropisomers, conformers, rotamers, tautomers, optical isomers, polymorphs, and geometric isomers. Any desired mixtures of these isomers fall

within the scope of the claims of the present disclosure. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other isomer(s) or when separated from the other isomer(s). Additionally, the person skilled in the art knows processes or methods or technology to separate, enrich, and/or to selectively prepare said isomers.

The meaning of various terms used in the description shall now be illustrated.
