     To a solution of 2-[[[5-benzoyl-3-chloro-2-pyridinyl]oxy]methyl]-α-(methoxyimino)-N-methyl-benzeneacetamide (1.0 g; 2.3 mmol) in THF (30 mL) was added a 3.0 M solution of methylmagnesium bromide in diethyl ether (4.6 mL; 13.7 mmol; 6 eq) at 0° C. The solution yellowed, and a precipitate appeared after a few minutes. The solution was warmed to room temperature where it was stirred for two hours. It was then cooled back down to 0° C. and quenched with aqueous ammonium chloride (20 mL). The aqueous layer was extracted twice with diethyl ether (10 mL), and the combined organic layers were washed with brine, dried over sodium sulfate and concentrated. The crude residue was passed through a plug of silica gel with the aid of diethyl ether to give the desired product (933 mg, 90%).

     2-[[[3-chloro-5-(1-phenylethenyl)-2-pyridinyl]oxy]methyl]-α-(methoxyimino)-N-methyl-benzeneacetamide (933 mg; 2.1 mmol) was dissolved in CH 2 Cl 2  (10 mL), and triethylamine (0.87 mL; 6.2 mmol; 3 eq) was added at room temperature followed by methanesulfonyl chloride (0.40 mL; 5.2 mmol; 2.5 eq). The reaction mixture stirred for 30 minutes and was quenched with water. The aqueous layer was extracted twice with diethyl ether (20 mL), and the combined organic layers were washed with 1N HCl followed by brine and then dried over sodium sulfate and concentrated. The crude product was purified by flash column chromatography using 80% diethyl ether in hexanes to give the desired product (778 mg, 87%).

     A 60% solution of N-methylmorpholine N-oxide in water (1.9 mL; 11.0 mmol; 1.5 eq) was added to a solution of 2-[[[3-chloro-5-(1-phenylethenyl)-2-pyridinyl]oxy]methyl]-α-(methoxyimino)-N-methyl-benzeneacetamide (3.2 g; 7.3 mmol) in aqueous acetone (30 mL acetone; 6 mL water) at room temperature. This was followed by the dropwise addition of a 4% solution of osmium tetroxide in water (1.43 mL; 0.18 mmol; 0.025 eq). The resulting reaction mixture stirred overnight, at which point sodium sulfite (250 mg) was added to quench any remaining oxidants. Stirring was continued until a black precipitate appeared, and the solution was diluted with water (15 mL) and extracted twice with EtOAc (30 mL). The combined organic layers were washed with saturated sodium chloride solution, dried over anhydrous sodium sulphate, filtered and concentrated. Purification by chromatography using a step gradient of 50-80% EtOAc in hexanes yielded the desired product as a brownish foam (3.5 g, 100%).

The bath was removed, and the reaction mixture stirred at room temperature overnight. It was then quenched with water (6 mL) and diluted with EtOAc (10 mL). The aqueous layer was extracted with EtOAc (6 mL), and the combined organic layers were washed with 1N hydrochloric acid followed by saturated sodium chloride solution, dried over anhydrous sodium sulphate, filtered and concentrated. The crude tosylate was purified by chromatography using 50% EtOAc in hexanes to afford 1.3 g (2.0 mmol; 80%) of the pure product as a white solid (M.P. 55-60° C.).

     The compounds of Formula (1) thus produced are usually obtained as a mixture of the E and Z forms, which can then be separated, via standard means known in the art, into each of those forms, if desired. 
     The compounds of Formula (1) show strong fungicidal activity against a wide variety of fungi. The following tests illustrate the fungicidal efficacy of the compounds of this invention. 
     Fungicide Utility 
     The compounds of the present invention have been found to control fungi, particularly plant pathogens. When employed in the treatment of plant fungal diseases, the compounds are applied to the plants in a disease inhibiting and phytologically acceptable amount. Application may be performed before and/or after the infection with fungi on plants. Application may also be made through treatment of seeds of plants, soil where plants grow, paddy fields for seedlings, or water for perfusion. The compounds may also be employed effectively for the control of fungi on wood, leather, carpet backings, or in paint. 
     As used herein, the term “disease inhibiting and phytologically acceptable amount” refers to an amount of a compound of the present invention which kills or inhibits the plant disease for which control is desired but is not significantly toxic to the plant. This amount will generally be from about 1 to 1000 ppm, with 10 to 500 ppm being preferred. The exact concentration of compound required varies with the fungal disease to be controlled, the type of formulation employed, the method of application, the particular plant species, climate conditions, and the like. A suitable application rate is typically in the range from about 0.10 to about 4 lb/A. 
     The compounds of the invention may also be used to protect stored grain and other non-plant loci from fungal infestation. 
     The following experiments were performed in the laboratory to determine the fungicidal efficacy of the compounds of the invention. 
     Compound Formulation: Compound formulation was accomplished by dissolving technical materials in acetone, with serial dilutions then made in acetone to obtain desired rates. Final treatment volumes were obtained by adding nine volumes 0.05% aqueous Tween-20 or Triton X-100, depending upon the pathogen. 
     Late Blight of Tomatoes ( Phytophthora infestans -PHYTIN): Tomatoes (cultivar Rutgers) were grown from seed in a soilless peat-based potting mixture (Metromix) until the seedlings were 1-2 leaf (BBCH 12). These plants were then sprayed to run off with the test compound at a rate of 100 ppm. After 24 hours the test plants were inoculated with an aqueous spore suspension of  Phytophthora infestans.  The plants were then transferred to the greenhouse until disease developed on the untreated control plants. 
     Powdery Mildew of Wheat ( Erysiphe graminis -ERYSGT): Wheat (cultivar Monon) was grown in a soilless peat-based potting mixture (Metromix) until the seedlings were 1-2 leaf (BBCH 12). These plants were then sprayed to run off with the test compound at a rate of 100 ppm. After 24 hours the test plants were inoculated with  Erysiphe graminis  by dusting spores from stock plants onto the test plants. The plants were then transferred to the greenhouse until disease developed on the untreated control plants. 
     Glume blotch of wheat ( Leptosphaeria nodorum -LEPTNO): Wheat (cultivar Monon) was grown from seed in a soilless peat-based potting mixture (Metromix) until the seedlings were 1-2 leaf (BBCH 12). These plants were then sprayed to run off with the test compound at a rate of 100 ppm. After 24 hours the test plants were inoculated with an aqueous spore suspension of  Leptosphaeria nodorum.  The plants were then transferred to the greenhouse until disease developed on the untreated control plants. 
     Brown rust ( Puccinia recondita -PUCCRT): Wheat (cultivar Monon) was grown from seed in a soilless peat-based potting mixture (Metromix) until the seedlings were 1-2 leaf (BBCH 12). These plants were then sprayed to run off with the test compound at a rate of 100 ppm. After 24 hours the test plants were inoculated with an aqueous spore suspension of  Puccinia recondita.  The plants were then transferred to the greenhouse until disease developed on the untreated control plants. 
     Septoria leaf spot ( Septoria tritici -SEPTTR): Wheat (cultivar Monon) was grown from seed in a soilless peat-based potting mixture (Metromix) until the seedlings were 1-2 leaf (BBCH 12). These plants were then sprayed to run off with the test compound at a rate of 100 ppm. After 24 hours the test plants were inoculated with an aqueous spore suspension of  Septoria tritici.  The plants were then transferred to the greenhouse until disease developed on the untreated control plants. 
     The following table presents the activity of typical compounds of the present invention when evaluated in these experiments. The effectiveness of the test compounds in controlling disease was rated using the following scale:

     The compounds of this invention are preferably applied in the form of a composition comprising one or more of the, compounds of Formula (1) with a phytologically-acceptable carrier. The compositions are either concentrated formulations which are dispersed in water or another liquid for application, or are dust or granular formulations which are applied without further treatment. The compositions are prepared according to procedures which are conventional in the agricultural chemical art, but which are novel and important because of the presence therein of the compounds of this invention. Some description of the formulation of the compositions is given to assure that agricultural chemists can readily prepare desired compositions. 
     The dispersions in which the compounds are applied are most often aqueous suspensions or emulsions prepared from concentrated formulations of the compounds. Such water-soluble, water suspendable, or emulsifiable formulations are either solids, usually known as wettable powders, or liquids, usually known as emulsifiable concentrates or aqueous suspensions. The present invention contemplates all vehicles by which the compounds of this invention can be formulated for delivery for use as a fungicide. As will be readily appreciated, any material to which these compounds can be added may be used, provided they yield the desired utility without significant interference with activity of the compounds of this invention as antifungal agents. 
     Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of the active compound, an inert carrier and surfactants. The concentration of the active compound is usually from about 10% to about 90% w/w, more preferably about 25% to about 75% w/w. In the preparation of wettable powder compositions, the toxicant products can be compounded with any of the finely divided solids, such as prophyllite, talc, chalk, gypsum, Fuller&#39;s earth, bentonite, attapulgite, starch, casein, gluten, montmorillonite clays, diatomaceous earths, purified silicates or the like. In such operations, the finely divided carrier is ground or mixed with the toxicant in a volatile organic solvent. Effective surfactants, comprising from about 0.5% to about 10% of the wettable powder, include sulfonated lignins, naphthalenesulfonates, alkylbenzenesulfonates, alkyl sulfates, and non-ionic surfactants, such as ethylene oxide adducts of alkyl phenols. 
     Emulsifiable concentrates of the compounds of this invention comprise a convenient concentration, such as from about 10% to about 50% w/w, in a suitable liquid. The compounds are dissolved in an inert carrier, which is either a water miscible solvent or a mixture of water-immiscible organic solvents, and emulsifiers. The concentrates may be diluted with water and oil to form spray mixtures in the form of oil-in-water emulsions. Useful organic solvents include aromatics, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as, for example, terpenic solvents, including rosin derivatives, aliphatic ketones, such as cyclohexanone, and complex alcohols, such as 2-ethoxyethanol. 
     Emulsifiers which can be advantageously employed herein can be readily determined by those skilled in the art and include various nonionic, anionic, cationic and amphoteric emulsifiers, or a blend of two or more emulsifiers. Examples of nonionic emulsifiers useful in preparing the emulsifiable concentrates include the polyalkylene glycol ethers and condensation products of alkyl and aryl phenols, aliphatic alcohols, aliphatic amines or fatty acids with ethylene oxide, propylene oxides such as the ethoxylated alkyl phenols and carboxylic esters solubilised with the polyol or polyoxyalkylene. Cationic emulsifiers include quaternary ammonium compounds and fatty amine salts. Anionic emulsifiers include the oil-soluble salts (e.g., calcium) of alkylaryl sulphonic acids, oil soluble salts or sulphated polyglycol ethers and appropriate salts of phosphated polyglycol ether. 
     Representative organic liquids which can be employed in preparing the emulsifiable concentrates of the present invention are the aromatic liquids such as xylene, propyl benzene fractions; or mixed naphthalene fractions, mineral oils, substituted aromatic organic liquids such as dioctyl phthalate; kerosene; dialkyl amides of various fatty acids, particularly the dimethyl amides of fatty glycols and glycol derivatives such as the n-butyl ether, ethyl ether or methyl ether of diethylene glycol, and the methyl ether of triethylene glycol. Mixtures of two or more organic liquids are also often suitably employed in the preparation of the emulsifiable concentrate. The preferred organic liquids are xylene, and propyl benzene fractions, with xylene being most preferred. The surface active dispersing agents are usually employed in liquid compositions and in the amount of from 0.1 to 20 percent by weight of the combined weight of the dispersing agent and active compound. The active compositions can also contain other compatible additives, for example, plant growth regulators and other biologically active compounds used in agriculture. 
     Aqueous suspensions comprise suspensions of water-insoluble compounds of this invention, dispersed in an aqueous vehicle at a concentration in the range from about 50 to about 50% w/w. Suspensions are prepared by finely grinding the compound, and vigorously mixing it into a vehicle comprised of water and surfactants chosen from the same types above discussed. Inert ingredients, such as inorganic salts and synthetic or natural gums, may also be added to increase the density and viscosity of the aqueous vehicle. It is often most effective to grind and mix the compound at the same time by preparing the aqueous mixture and homogenizing it in an implement such as a sand mill, ball mill, or piston-type homogenizer. 
     The compounds may also be applied as granular compositions, which are particularly useful for applications to the soil. Granular compositions usually contain from about 0.5% to about 10% w/w of the compound, dispersed in an inert carrier which consists entirely or in large part of coarsely divided attapulgite, bentonite, diatomite, clay or a similar inexpensive substance. Such compositions are usually prepared by dissolving the compound in a suitable solvent and applying it to a granular carrier which has been preformed to the appropriate particle size, in the range of from about 0.5 to about 3 mm. Such compositions may also be formulated by making a dough or paste of the carrier and compound, and crushing and drying to obtain the desired granular particle. 
     Dusts containing the compounds are prepared simply by intimately mixing the compound in powdered form with a suitable dusty agricultural carrier, such as, for example, kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1% to about 10% w/w of the compound. 
     The active compositions may contain adjuvant surfactants to enhance deposition, wetting and penetration of the compositions onto the target crop and organism. These adjuvant surfactants may optionally be employed as a component of the formulation or as a tank mix. The amount of adjuvant surfactant will vary from 0.01 percent to 1.0 percent v/v based on a spray-volume of water, preferably 0.05 to 0.5 percent. Suitable adjuvant surfactants include ethoxylated nonyl phenols, ethoxylated synthetic or natural alcohols, salts of the esters or sulphosuccinic acids, ethoxylated organosilicones, ethoxylated fatty amines and blends of surfactants with mineral or vegetable oils. 
     The composition may optionally include fungicidal combinations which comprise at least 1% of one or more of the compounds of this invention with another pesticidal compound. Such additional pesticidal compounds may be fungicides, insecticides, nematocides, miticides, arthropodicides, bactericides or combinations thereof that are compatible with the compounds of the present invention in the medium selected for application, and not antagonistic to the activity of the present compounds. Accordingly, in such embodiments the other pesticidal compound is employed as a supplemental toxicant for the same or for a different pesticidal use. The compounds in combination can generally be present in a ratio of from 1:100 to 100:1. 
     The present invention includes within its scope methods for the control or prevention of fungal attack. These methods comprise applying to the locus of the fungus, or to a locus in which the infestation is to be prevented (for example applying to cereal or grape plants), a fungicidal amount of one or more of the compounds of this invention or compositions. The compounds are suitable for treatment of various plants at fungicidal levels, while exhibiting low phytotoxicity. The compounds are useful in a protectant or eradicant fashion. The compounds of this invention are applied by any of a variety of known techniques, either as the compounds or as compositions including the compounds. For example, the compounds may be applied to the roots, seeds or foliage of plants for the control of various fungi, without damaging the commercial value of the plants. The materials are applied in the form of any of the generally used formulation types, for example, as solutions, dusts, wettable powders, flowable concentrates, or emulsifiable concentrates. These materials are conveniently applied in various known fashions. 
     The compounds of this invention have been found to have significant fungicidal effect particularly for agricultural use. Many of the compounds are particularly effective for use with agricultural crops and horticultural plants, or with wood, paint, leather or carpet backing. 
     In particular, the compounds effectively control a variety of undesirable fungi which infect useful plant crops. Activity has been demonstrated for a variety of fungi. It will be understood by those in the art that the efficacy of the compounds of this invention for the foregoing fungi establishes the general utility of the compounds as fungicides. 
     The compounds of this invention have broad ranges of efficacy as fungicides. The exact amount of the active material to be applied is dependent not only on the specific active material being applied, but also on the particular action desired, the fungal species to be controlled, and the stage of growth thereof, as well as the part of the plant or other product to be contacted with the toxic active ingredient. Thus, all the active ingredients of the compounds of this invention, and compositions containing the same, may not be equally effective at similar concentrations or against the same fungal species. The compounds of this invention and compositions are effective in use with plants in a disease inhibiting and phytologically acceptable amount. The term “disease inhibiting and phytologically acceptable amount” refers to an amount of a compound which kills or inhibits the plant disease for which control is desired, but is not significantly toxic to the plant. This amount will generally be from about 1 to about 1000 ppm, with 10 to 500 ppm being preferred. The exact concentration of compound required varies with the fungal disease to be controlled, the type of formulation employed, the method of application, the particular plant species, climate conditions, and the like. A suitable application rate is typically in the range from about 0.10 to about 4 pounds/acre.
