Description: SUBSTITUTED 4,5-DIHYDRO-1 ,2,4-TRIAZIN-6-ONES, 1 ,2,4-TRIAZIN-6- ONES, AND THEIR USE AS FUNGICIDES AND INSECTICIDES This application claims priority from U.S. provisional application 60/243,803, which was filed on October 27, 2000. The need continues for novel and improved broad spectrum, agrochemical fungicides and insecticides. This is particularly so since the targets of fungicides and insecticides can become resistant to known fungicides and insecticides over time and after use of such compounds and their compositions. Additionally, economic and environmental considerations can favor fungicides and insecticides having different modes of performance than those currently used. This invention relates to dihydrotriazinones, triazinones and related compounds, compositions comprising such compounds and an agronomically acceptable carrier, and the use thereof as broad spectrum fungicides and insecticides. This invention also teaches methods of preparing these compounds as well as methods of using the compounds as fungicides and insecticides.

A fourth embodiment of the present invention relates to a method of controlling a fungus comprising applying a fungicidally effective amount of a fungicidal composition comprising a compound of formula (IA) to the fungus, to the locus of the fungus or to the growth medium of said fungus. A fifth embodiment of the present invention relates to a method of controlling an insect comprising applying an insecticidally effective amount of an insecticidal composition comprising a compound of formula (IB) to the insect, to the locus of the insect or to the growth medium of said insect. The compounds of this invention can be made by the using methods A-K: Method A: Intermediate 2 The imidic esters (intermediate 1) can be formed by standard methods (for example, Neilson, D. G. in "The Chemistry of Amidines and Imidates", (S. Patai, ed.), Wiley Publishing Co., New York, NY (1975) pp. 385-413 and references therein; Kiessling, A. J and McClure, C. K., Synthetic Communications 27(5), 923-927 (1997); and Schafer, F. C and Peters, G. A., J. Org. Chem. (1961) 26, 412). In the above equation, X is a counter ion such as chloride or bromide, and Y is alkyl or aryl. The imidic esters may be neutral, or they may be salts; in the case of salts, roughly one equivalent of base is added to the reaction. The reactions can be run in methylene chloride, dioxane with a small amount of ethanol, alcohol solvents such as ethanol, methanol or isopropanol, or preferably in methylene chloride with 5% ethanol. The reactions can be run at room temperature or heated. The product intermediate 2 is reacted with a hydrazine to give the desired product. Solvents for this reaction include tetrahydrofuran, dioxane, or preferably an alcohol such as ethanol, propanol, etc. Alternatively, intermediate 2 can be prepared from an acylated arnino acid as shown, using triethyloxonium tetrafluoroborate (or related derivatives) or methyl triflate, as shown for method B. Method B: Intermediate 3 Intermediate 2 Method C: Solid phase synthesis can be used to make compound of this invention. Method D: Compounds described in this invention can be made from acylated arnino acids by the reaction shown in the scheme below. The preparation of the thioamide was carried out with phosphorous pentasulfide in toluene at 90°C, however, other reagents such as Lawesson's reagent and other solvents can be used. The alkylation of the thioamide was carried out using methyl iodide in methanol with sodium methoxide or in acetone with potassium carbonate as the base. The reaction of the intermediates with hydrazines is preferably run in alcohol solvents. Intermediate 3 Method E: The dihydrotriazinones may be oxidized to the triazinones by using 2,3- dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The reaction is preferably run in ethyl acetate, although other solvents, such as aromatic hydrocarbons, can be used. Occasionally, oxidation of a dihydrotriazinone to a triazinone occurs spontaneously during a reaction or during purification. Method F: Compounds can be alkylated at N 1 using a strong base such as sodium hydride or potassium f-butoxide in solvents such as DMF or THF. R 1 X is any alkylating agent. Method G: N 4 can be derivatized using a strong base such as sodium hydride or potassium f-butoxide and an electrophile. For reactive electrophiles such as di-fe/t-butyl dicarbonate, either no base or a mild base, such as triethylamine, is required. Method H: The carbonyl can be converted to a thiocarbonyl using phosphorus pentasulfide in toluene. Both other reagents, such as Lawesson's reagent, and other solvents could be used. Method I: The 1 ,2,4-triazin-6-ones can react with nucleophiles such as alcohols or thiols to form 5-substituted derivatives. Method J: 1 ,2,4-Triazin-5,6-diones can be prepared by from the amidrazone by reaction with oxalyl chloride or diethyl oxalate. Method K: A Grignard reagent can be added to a 1 ,2,4-triazin-6-one in a suitable solvent, such as ether or THF to give a 5-substituted dihydrotriazinone.

Compound 292 Table 3: Spectral Characterization for Compounds 1-292 σs Ul \ -4 \ -4 © -4 -4 Ul -4 Ul -4 -4 -4 -4 SO © MISSING AT THE TIME OF FILING The compounds of the present invention have fungitoxic activity, particularly against phytopathogenic fungi. They are active against fungi of a number of classes including Deuteromycetes (Fungi Imperfecti), Basidiomycetes, Phycomycetes and Ascomycetes. More particularly, the method of this invention provides for activity against organisms including, but not limited to, Pyricularia oryzae, Erysiphe graminis, Puccinia recondita, Colletotrichum lagenarium, Helminthosporium species, Alternaria solani, Septo a nodorum, Sclerotinia species, Sphaerotheca fuliginea, Plasmopara viticola, Pseudoperonospora cubensis, Cercospora species, Uncinula necator and Podosphaera leucotricha. More particularly, rice diseases are controlled by the method of the invention. Examples of such rice diseases are seedbome diseases, soilborne diseases, and seedling box and field diseases such as those caused by Pyricularia oryzae and Rhizoctonia species. Additional diseases include powdery mildew incited by Sphaerotheca fulignea (e.g, cucurbit powdery mildew), Uncinula necator (e.g, grape powdery mildew), and Podosphaera leucotricha (e.g, apple powdery mildew). Cereal diseases are controlled such as those caused by Erysiphe graminis, Puccinia recondita, Septoha nodurum and Helminthosporium species. Tomato and potato diseases are controlled such as those caused by Alternaria solani. The compounds of the invention can be applied as fungicidal sprays by methods commonly employed, such as conventional high-gallonage hydraulic sprays, low-gallonage sprays, air-blast, aerial sprays and dusts. Such use conveniently permits treatment of fungal infestations in crops such as vegetables, fruits, ornamentals, seeds, turf, cereal and vines among other plants. The dilution and rate of application will depend upon the type of equipment employed, the method and frequency of application desired and diseases to be controlled, but the effective amount is usually from about 0.01 kilogram (kg) to about 20 kg, of active ingredient (a.i.) per hectare (ha). As a foliar fungicide, a compound of the present invention is usually applied to growing plants at a rate of about 0.1 to about 5 and preferably from about 0.125 to about 0.5 kg per hectare. As a seed protectant, the amount of toxicant coated on the seed is usually at a dosage rate of about 10 to about 250 grams (g) and preferably from about 20 to about 60 g per 50 kilograms of seed. As a soil fungicide, the chemical can be incorporated in the soil or applied to the surface usually at a rate of 0.5 to about 20 kg and preferably about 1 to about 5 kg per hectare. The compounds of the present invention are useful for the control of fungi and can be utilized at various loci such as the seed, the water surface, the soil or the foliage. For such purposes, these compounds can be used in the technical or pure form as prepared, as solutions or as formulations. The compounds are usually taken up in a carrier or are formulated so as to render them suitable for subsequent use as fungicides. For example, these chemical agents can be formulated as wettable powders, dry powders, emulsifiable concentrates, dusts, granular formulations, aerosols, or flowable emulsion concentrates. In such formulations, the compounds are extended with a liquid or solid carrier and when desired suitable surfactants are incorporated. It is usually desirable, particularly in the case of foliar spray formulations, to include adjuvants, such as wetting agents, spreading agents, dispersing agents, stickers, adhesive and the like in accordance with agricultural practices. Such adjuvants commonly used in the art can be found in McCutcheon's Emulsifiers and Detergents, McCutcheon's Emulsifiers and Detergents and McCutcheon's Functional Materials all published annually by McCutcheon Division of MC Publishing Company (New Jersey). In general, the compounds utilized in this invention can be dissolved in appropriate solvents such as acetone, methanol, ethanol, dimethylformamide or dimethyl sulfoxide and such solutions extended with water. The concentrations of the solution can vary from 1% to 90% with a preferred range being 5 to 50%. For the preparation of emulsifiable concentrates, the compounds of the invention can be dissolved in suitable organic solvents or a mixture of solvents, together with an emulsifying agent which permits dispersion of the fungicide in water. The concentration of the active ingredient in emulsifiable concentrates is usually 10% to 90% and in flowable emulsion concentrates; this can be as high as 75%. Wettable powders suitable for spraying can be prepared by admixing the compound with finely divided solid, such as inorganic silicates and carbonates, and silicas and incorporating wetting agents, sticking agents, and/or dispersing agents in such mixtures. The concentration of active ingredients in such formulations is usually in the range of 20% to 98%, preferably 40% to 75%. A typical wettable powder is made by blending 50 parts of a compound of this invention, 45 parts of a synthetic precipitated hydrated silicon dioxide sold under the trademark Hi-Sil ® and 5 parts of sodium lignosulfonate (Marasperse ® N-22). In another preparation of a Kaolin type, (Barden) clay is used in place of the Hi-Sil in the above wettable powder and in another such preparation 25% of the Hi-Sil is replaced with a synthetic sodium silicoaluminate sold under the trademark Zeolex ® 7. Dusts are prepared by mixing the compounds of the invention with finely divided inert solids which can be organic or inorganic in nature.

Fungicidal Testing Protocols and Test Data Examples of diseases against which the compounds of the invention are useful include rice diseases such as rice blast, rice sheath blight and helmenthosporium leaf spot, cereal diseases such as wheat powdery mildew, wheat leaf rust, and septoria, tomato and potato early blight, peanut early leaf spot, grape and cucumber powdery mildew, apple scab, apple powder mildew, brown rot of fruits, cucumber anthracnose and bean powdery mildew. Fungicide screening for control of Rice Blast and Cucumber Powdery Mildew Plant Propagation: Plants used in the fungicide testing program were grown in 2-1 /4-inch (5.7-cm). square pots containing RediEarth propagation substrate. The plants were raised under greenhouse conditions. The rice plants were 12- days-old and cucumbers were 13-days-old at the time of spraying with chemical treatments. Sample Preparation: The sample of the experimental chemical was weighed and dissolved in an acetone-methanol-water solution (A/M/W at 1 :1 :2 ratio by volume). Spraying Procedure: After sprayer calibration, the test solutions were poured into the fungicide sprayer. The fungicide sprayer contains three spray nozzles, located approximately 10 cm above and to the sides of the plants. The spray produced by the nozzles results in uniform coverage of both the upper and lower parts of the plant leaves. After spraying, the treated plants were placed in a drying chamber for 4 hours, prior to sorting. Cucumber Powdery Mildew: Cucumber Powdery Mildew (CPM), caused by the fungus Sphaerotheca fuliginea, was maintained on large cucumber plants. For inoculum preparation, five to eight leaves depending on size, completely covered with powdery mildew spores, were collected. The leaves were placed in a glass jar and covered with 500 ml of water, containing 5 drops of Tween- 80. The material was filtered through two layers of cheesecloth to remove leaf fragments. The spore count was adjusted to 2 x 10 5 spores per ml. Cucumber plants, cv. "Bush Champion," were used for this test. The plants were thinned to one per pot after the cotyledons were fully developed. Two days before the test, the small leaves and meristem region were removed, leaving only the cotyledons and one large true leaf. The protectant tests required that the cucumber plants be inoculated 1 day after spraying with the chemical treatment. The plants were inoculated with a hand-held spray bottle with the suspension of fungal spores. The leaves were lightly misted on the upper surface from two different spray directions. Disease development occurred in the greenhouse. After seven days, the plants were evaluated for percent of disease control. The results are reported as percent control; 100 is total disease control, 0 is no disease control. Rice Blast: Rice Blast (RB), caused by the fungus Pyricularia oryzae, was maintained on potato dextrose agar (PDA) plates under fluorescent lamps at room temperature. Six different isolates of the fungus were used to prepare the inoculum. Approximately 5 plates of each isolate were used to prepare 250 ml of inoculum. The plates were flooded with water and scraped gently with a rubber spatula. The spore suspension was filtered through one layer of cheese cloth to remove mycelial fragments and agar pieces. The spore count was adjusted to achieve a concentration of 5 x 10 6 spores per ml. Rice plants cv. "M-201 ," were used for this test. The protectant tests required that the rice plants be inoculated 1 day after spraying with the chemical treatment. The curative tests in the primary screen required that the plants be inoculated 1 day after spraying with the treatment. The plants were inoculated with fungal spores using a DeVilbiss atomizer, using a spray pressure of 30 psi (200 kPa). The inoculated plants were quickly placed in a mist chamber with 100% relative humidity (RH) at 20°C for one day and two nights; approximately 40 hours. The plants were moved to the greenhouse for disease development. Six days after inoculation, the treatment comparisons were made. The results are reported as percent control; 100 is total disease control, 0 is no disease control.

NT means not tested. a Compound 273 was prepared and tested as a 1:1 mixture with its unoxidized (dihydro) form. For insecticidal use, the compositions and compounds of this invention can be applied directly to the locus to be protected, as for example, the area around or upon economic plants infected with insects or to plants on which infestation is to be prevented. Examples of injurious insects belong to the orders Lepidoptera, Coleoptera, Diptera, Thysanoptera, Hymenoptera, Heteroptera, Homoptera, Orthoptera, and Acarina. The compounds and compositions may be used either as contact or systemic pesticides. The compounds of the invention are applied to the insect's habitat at a rate of 0.0005 to 10 kilograms per hectare, preferably 0.05 to 5 and most preferably from 0.1 to 1 kilogram per hectare. In the practice of the method of the invention, the active compound may be applied to the soil or foliage where it is absorbed by the plant, translocated to other plant parts and ultimately ingested by the pest or insects by means of ingestion of the plant part(s). This means of application is referred to as "systemic" application. Alternatively, the active compound may be applied to the soil and contacted therein with the insects and other pests to be controlled. This means of application is referred to as "soil" application. In another alternative, the active compound may be foliarly applied to the plants to be freed from insects and other pests which feed on the foliage. The active compounds of the present invention may be employed alone or in the form of mixtures with one another and/or with such solid and/or liquid dispersible carrier vehicles and/or with other known compatible active agents, especially plant protection agents, such as other insecticides, arthropodicides, nematicides, fungicides, bactericides, rodenticides, herbicides, fertilizers, growth-regulating agents, synergists. In the compositions of the invention, the active compound is present in an amount substantially between about 0.0001-99% by weight. For compositions suitable for storage or transportation, the amount of active ingredient is preferably between about 0.5-90% by weight, and more preferably between about 1-75% by weight of the mixture. Compositions suitable for direct application or field application generally contain the active compound in an amount substantially between about 0.0001-95%, preferably between about 0.0005-90% by weight, and more preferably between about 0.001-75% by weight of the mixture. The composition can also be stated as a ratio of the compound to the carrier. In the present invention the weight ratio of these materials (active compound/carrier), can vary from 99:1 to 1:4 and more preferably from 10:1 to 1:3. In general, the compounds of this invention can be dissolved in certain solvents such as acetone, methanol, ethanol, dimethylformamide, pyridine or dimethyl sulfoxide and such solutions can be diluted with water. The concentrations of the solution can vary from about 1% to about 90% with a preferred range being from about 5% to about 50%. For the preparation of emulsifiable concentrates, the compound can be dissolved in suitable organic solvents, or a mixture of solvents, together with an emulsifying agent to enhance dispersion of the compound in water. The concentration of the active ingredient in emulsifiable concentrates is usually from about 10% to about 90%, and in flowable emulsion concentrates, can be as high as about 75%. The active compounds can be applied as insecticide sprays by methods commonly employed, such as conventional high-gallonage hydraulic sprays, low gallonage sprays, ultra-low-volume sprays, airblast spray, aerial sprays, and dusts. The present invention also contemplates methods of killing, combatting or controlling pests which compromises contacting pests with a combative or toxic amount (i.e. a pesticidally effective amount) of at least one active compound of the invention alone or together with a carrier vehicle (composition or formulation) as noted above. The term "contacting" as employed in the specification and claims means applying to at least one of (a) such pests and (b) the corresponding habitat thereof (i.e, the locus to be protected, for example, to a growing crop or to an area where a crop is to be grown) the active compound of this invention alone or as a constituent of a composition or formulation. In addition to the aforementioned ingredients the preparations according to the invention may also contain other substances commonly used in preparations of this kind. For example, a lubricant, such as calcium stearate or magnesium stearate, may be added to a wettable powder or to a mixture to be granulated. Furthermore there may, for example, be added "adhesives" such as polyvinylalcohol-cellulose derivatives or other colloidal materials, such as casein, to improve the adherence of the pesticide to the surface to be protected. Insecticidal Testing Protocol and Test Data Numerous compounds of this invention were tested for insecticidal activity. This testing was carried out using two different protocols. Protocol 1 : Test Solution Preparation A test solution containing 1250 parts per million (ppm) was prepared by dissolving the test compound in 15 milliliters of solvent (acetone: methanol, 1 :1) and then adding 65 milliliters of a second solvent (acetone: water, 1 :1) to give an acetone : water : methanol system of 50 : 40 : 10. Sprayer The enclosed spraying chamber consisted of a single spray nozzle mounted on a boom moving at a fixed speed and distance over stationary targets. The vertical distance from the nozzle tip to the targets was adjusted to give rates varying from 150 g/ha to 600 g/ha 3. Test Species Tests were conducted with the following pests, Foliar Species SYMBOL COMMON NAME LATIN NAME AW Southern Armyworm Spodoptera eridania BB Mexican Bean Beetle Epilachna verivestis MTA Two-Spotted Spider Mite Tetranychus urticae Southern Armvworm Individual fully expanded primary lima bean (Phaseolus limensis) leaves were placed bottom side up on moistened pieces of filter paper in Petri dishes. The leaves were sprayed with the test solutions and allowed to dry. The dishes were infested with 5 third instar larvae of the southern armyworm, covered with the lids, and held at 27°C. Armyworm control was rated by visual inspection after 48 hours. A rating of 100 indicated that all larvae were dead. A rating of 0 indicated no dead larvae and normal feeding. Intermediate control was indicated by intermediate ratings. Mexican Bean Beetle Individual fully expanded primary lima bean (Phaseolus limensis) leaves were placed bottom side up on moistened pieces of filter paper in Petri dishes. The leaves were sprayed with the test solutions and allowed to dry. The dishes were infested with 5 third instar larvae of the mexican bean beetle, covered with the lids, and held at 27°C. Bean beetle control was rated by visual inspection after 48 hours. A rating of 100 indicated that all larvae were dead. A rating of 0 indicated no dead larvae and normal feeding. Intermediate control was indicated by intermediate ratings. C. Two Spotted Spider Mite A pad of moistened cotton was placed in a Petri dish. A 1 - inch square section cut from a fully expanded primary lima bean (Phaseolus limensis) leaf was positioned bottom side up on the moist cotton. The leaf square was infested with approximately 50 adult female mites. The dishes were sprayed with the test solutions and held at 27°C. for mortality determination 1-day post-treatment. The percentage of mites killed were rated from 100% (all dead) to 0% (all alive). Protocol 2: Candidate compounds are solubilized in a solvent mix (either acetone/methanol/water or DMSO/water). The compounds are screened against Aedes aegypti (yellowfever mosquito, YFM) or Caenorhabditis elegans nematode (CE). For screening A. aegypti, wells are filled with 1 mL of diet (500 ppm of a 1:1 liver powder/yeast in D.I. water). The appropriate volume of test material is added to the wells to provide a final concentration of 3 ppm. Approximately 10-15 three (3) day old mosquito larvae are used for infesting the test wells. Mosquito larva trays are stored in an 27°C room and mortality readings taken 3 days after infesting. A compound is declared active if all organisms within the test well are dead at reading time. For screening C. elegans, wells are filled with 1 mL of E.coli diet (cell density = 4% transmittance at 535 nM). The appropriate volume of test material is added to the wells to provide a final concentration of either 15 or 20 ppm. Approximately 10-15 four (4) day old nematodes are used for infesting the test wells. Test plates are stored at 21 °C and mortality readings taken 6 days after infesting. A compound is declared active if all organisms within the test well are dead at reading time. Y = yes (active); N = no (inactive); NT = not tested.
