This disclosure relates to the field of molecules having pesticidal utility against pests in Phyla Nematoda, Arthropoda, and Mollusca, processes to produce such molecules and intermediates used in such processes, compositions containing such molecules, and processes of using such molecules against such pests. These molecules may be used, for example, as nematicides, acaricides, insecticides, miticides, and molluscicides.
“Many of the most dangerous human diseases are transmitted by insect vectors” (Rivero, A. et al., Insect Control of Vector-Borne Diseases: When is Insect Resistance a Problem? Public Library of Science Pathogens, 6(8) (2010)). Historically, vector-borne diseases, such as, malaria, dengue, yellow fever, plague, and louse-borne typhus, among others, were responsible for more human disease and death from the 1600's through the early 1900's than all other causes combined (Gubler D., Resurgent Vector-Borne Diseases as a Global Health Problem, Emerging Infectious Diseases, Vol. 4, No. 3, July-September (1998)). Currently, vector-borne diseases are responsible for about 17% of the global parasitic and infectious diseases. It has been estimated that about 250 million people around the world have malaria and about 800,000 deaths occur each year—85% of those deaths are children under the age of five. A further 250,000 to 500,000 cases of dengue hemorrhagic fever occur each year (Matthews, G., Integrated Vector Management: controlling vectors of malaria and other insect vector borne diseases (2011)). Vector control plays a critical role in the prevention and control of infectious diseases. However, insecticide resistance, including resistance to multiple insecticides, has arisen in all insect species that are major vectors of human diseases (Rivero, A. et al.).
Each year insects, plant pathogens, and weeds destroy more than 40% of all potential food production. This loss occurs despite the application of pesticides and the use of a wide array of non-chemical controls, such as crop rotations and biological controls. If just some of this food could be saved, it could be used to feed the more than three billion people in the world who are malnourished (Pimental, D., Pest Control in World Agriculture, Agricultural Sciences—Vol. II (2009)).
Plant parasitic nematodes are among the most widespread pests, and are frequently one of the most insidious and costly. It has been estimated that losses attributable to nematodes are from about 9% in developed countries to about 15% in undeveloped countries. However, in the United States of America, a survey of 35 States on various crops indicated nematode-derived losses of up to 25% (Nicol, J. et al., Current Nematode Threats to World Agriculture, Genomic and Molecular Genetics of Plant-Nematode Interactions (Eds. Jones, J. et al.), Chapter 2, (2011)).
It is noted that gastropods (slugs and snails) are pests of less economic importance than insects or nematodes, but in certain areas, gastropods may reduce yields substantially, severely affecting the quality of harvested products, as well as transmitting human, animal, and plant diseases. While only a few dozen species of gastropods are serious regional pests, a handful of species are important pests on a world-wide scale. In particular, gastropods affect a wide variety of agricultural and horticultural crops, such as arable, pastoral, and fiber crops; vegetables; bush and tree fruits; herbs; and ornamentals (Speiser, B., Molluscicides, Encyclopedia of Pest Management (2002)).
Termites cause damage to all kinds of private and public structures, as well as to agricultural and forestry resources. In 2003, it was estimated that termites cause over US$20 billion in damage world-wide each year (Su, N.Y., Overview of the global distribution and control of the Formosan subterranean termite, Sociobiology 2003, 41, 177-192).
Therefore, for many reasons, including the above reasons, a need exists for new pesticides.

Many of the molecules of Formula One may be depicted in two or more tautomeric forms such as when R1, R2, or R4, is H (see for example, “Scheme TAU” below). For the sake of simplifying the schemes, all molecules have been depicted as existing as a single tautomer. Any and all alternative tautomers are included within the scope of this Formula One, and no inference should be made as to whether the molecule exists as the tautomeric form in which it is drawn.
The molecules of Formula One will generally have a molecular mass of about 400 Daltons to about 1200 Daltons. However, it is generally preferred if the molecular mass is from about 300 Daltons to about 1000 Daltons, and it is even more generally preferred if the molecular mass is from about 400 Daltons to about 750 Daltons.
Thiobiurets disclosed herein are prepared from the corresponding isocyanate, Ar1-Het-Ar2-L-NCO (1-2). Usually, these isocyanates are not isolated, but are instead generated in situ from a suitable precursor and used directly in the preparation of a thiobiuret. One such suitable precursor is an amine (1-1) which can be converted into an isocyanate by using one of several common reagents such as phosgene, diphosgene, triphosgene, or carbonyldiimidazole (Scheme 1, step a), in a mixed solvent system such as dichloromethane and water or diethyl ether and water, in the presence of a base such as sodium bicarbonate or triethylamine, at temperatures from about −10° C. to about 50° C.
Alternatively, the isocyanates may be generated via a Curtius rearrangement of an acyl azide, Ar1-Het-Ar2-L-C(O)N3 (1-4), which is, in turn, prepared from the corresponding carboxylic acid precursor, Ar1-Het-Ar2-L-CO2H (1-3). Formation of an acyl azide (Scheme 1, step b) occurs either by treatment of the acid with ethyl chloroformate and sodium azide in the presence of an amine base such as triethylamine, or with diphenylphosphoryl azide in the presence of an amine base such as triethylamine. The acyl azide is then made to undergo a Curtius rearrangement (which may need to be thermally induced), leading to the corresponding isocyanate (1-3). Depending on the nature of the particular acyl azide, this rearrangement may occur spontaneously at ambient temperature, or it may require heating from about 40° C. to about 100° C. in a suitable solvent, such as toluene, or acetonitrile, or an ethereal solvent such as dioxane or tetrahydrofuran. Azides of arylacetic acids are known, though frequently, due to their reactivity, they are not isolated as pure solids. Accordingly, the acyl azide intermediate is not always fully characterized, but may simply be heated directly without characterization, to generate the isocyanate.
An isocyanate, Ar1-Het-Ar2-L-NCO (1-2), can be treated directly with an N-aryl thiourea (2-1) in the presence of about 0.1 to about 2 equivalents of an inorganic base such as cesium carbonate or sodium hydride, resulting in the formation of a thiobiuret (2-2, Scheme 2). The reaction can be performed at temperatures from about 0° C. to about 100° C., preferably from about 20° C. to about 80° C., in an aprotic solvent or solvent mixture chosen from acetonitrile, acetone, toluene, tetrahydrofuran, 1,2-dichloroethane, dichloromethane, or mixtures thereof, but use of acetonitrile is preferred.
Thiobiurets (2-2) generated in situ can be converted directly without purification into a variety of cyclized analogs (Scheme 3), or they can be isolated from the reaction medium prior to cyclization. Cyclization can be achieved by treatment with an α-halo ester such as methyl bromoacetate to form 2-imino 1,3-thiazolin-4-ones (3-1, step a) unsubstituted or mono- or di-substituted with R5; vicinal dihalides such as 1-bromo-2-chloroethane or 1,2-dichloroethane, to form 2-imino-1,3-thiazolines (3-2, step b) unsubstituted or mono-substituted with R5 or R6; α-halo ketones such as chloroacetone to form 2-imino-1,3-thiazoles (3-3, step c) unsubstituted with R5 or R6; or 1,3-dihalopropanes such as 1-bromo-3-chloropropane to form 2-imino-1,3-thiazinanes (3-4, step d) unsubstituted or mono-substituted with R5 or R6 or unsubstituted or mono- or di-substituted with R7. With step a, use of sodium acetate in a protic solvent such as ethanol or methanol, at temperatures ranging from about 20° C. to about 70° C. is preferred. With step b, use of an inorganic base such as potassium carbonate in a solvent such as acetonitrile or (preferably) 2-butanone, at a temperature between about 0° C. and about 80° C., is preferred.
An alternative method for preparing analogs having the general structure 3-1′ (Scheme 3) is described in Scheme 3a, Intermediate 2-iminolthiazolidin-4-one (3-1a, step a) is reacted directly with an isocyanate (1-2), in the presence of about 0.1 to about 2 equivalents of an inorganic base such as cesium carbonate or sodium hydride to form cyclized thiobiuret (3-1′). The reaction can be performed at temperatures from about 0° C. to about 100° C., preferably from about 20° C. to about 80° C., in an aprotic solvent or solvent mixture chosen from acetonitrile, acetone, toluene, tetrahydrofuran, 1,2-dichloroethane, dichloromethane, or mixtures thereof, but use of acetonitrile is preferred.
Alternatively, the 2-iminothiazolidin-2-one (3-1a) may be reacted with 4-nitrophenyl chloroformate (step b), forming a 4-nitrophenyl carbamate intermediate (3-2a). This reaction is conducted with equimolar quantities of the imine and the chloroformate, in a polar aprotic solvent such as tetrahydrofuran or dioxane, and in the presence of from about 0.1 to about 2 equivalents of an inorganic base such as cesium carbonate or potassium carbonate, preferably at room temperature. The intermediate (3-2a) may be isolated by filtration from inorganic salts and evaporation of solvent, or it can be used directly in step c. In step c, treatment of 3-2a with a primary alkyl amine Ar1-Het-Ar2-L-NHR1, wherein R1 is H or alkyl, may generate cyclized thiobiuret (3-1′). Step c may also be conducted in the presence of an inorganic base such as cesium carbonate or potassium carbonate, from about 0.1 to about 2 equivalents, preferably about 1 to about 1.2 equivalents; it is also most conveniently run at room temperature, although it may be run at temperatures from about 0° C. to about 100° C.
Thiobiurets (2-2) can also be converted into novel S-alkylated analogs as described in Scheme 3b. For example, reaction of a thiobiuret 2-2 with an alkyl iodide (step a), in a protic solvent such as ethanol, and in the presence of a base such as sodium acetate, at temperatures from about 0° C. to about 60° C., results in formation of an S—R2 substituted product (3-1b). A variation of the reaction conditions described in Scheme 3, step c, employs careful control of reaction conditions to ensure that the temperature does not exceed 20° C. Under these conditions, 4-hydroxy-2-iminothiazolidines (3-2b, step b) may be isolated.
Analogs of Formula 1 wherein R2 and R4 are cyclized to form a 2-(R5)-4-(R3)-5-imino-1,2,4-thiadiazolidin-3-one (3-4c) may be constructed as described in Scheme 3c. Following the work described by Kaugers, et al (J. Org. Chem 1992, 57, 1671), an N-arylamino 1,2,3,4-thiatriazole (3-1c), prepared in one step from the corresponding N3-aryl thiosemicarbazone by oxidation with sodium nitrite, is treated with an alkyl isocyanate to form 3-2c. Treatment of 3-2c with a base such as sodium methoxide in methanol at room temperature (step b) results in cleavage of the urea bond and formation of a 2-(R5)-4-(R3)-5-imino-1,2,4-thiadiazolidin-3-one (3-3c). This imine may then be treated with an isocyanate under conditions equivalent to those described in Scheme 3a, step a, to form 3-4c.
Molecules of Formula One can be prepared by making a triaryl intermediate, Ar1-Het-Ar2, and then linking it to an appropriate intermediate to form a desired compound. A wide variety of triaryl intermediates can be used to prepare molecules of Formula One, provided that such triaryl intermediates contain a suitable functional group on Ar2 to which the rest of the desired functional group can be attached. Suitable functional groups include an amino, isocyanate, carboxyl, or a halogen (preferably bromo or iodo). These triaryl intermediates can be prepared by methods previously described in the chemical literature, including Crouse, et al., WO2009102736 (the entire disclosure of which is hereby incorporated by reference).
The triaryl aldehydes used as precursors in preparation of the molecules of Formula One can be prepared according to procedures described in Crouse, et al., US 2012/0202688 A1. Some of the procedures described above require use of halo-aryl intermediates, Ar1-Het-Ph-Br, which are novel intermediates. These may be prepared as described in Scheme 4. 3-(4-Bromophenyl)-1,2,4-triazole (4-2, step a) is prepared in two steps from 4-bromobenzamide (4-1) under conditions described previously (Crouse, et al., WO2009102736). This triazole can then be coupled to an aryl halide (R═C1-C6 haloalkoxy) such as 4-trifluoromethoxyphenyl bromobenzene, in the presence of cesium carbonate or potassium phosphate, in a polar aprotic solvent such as dimethylformamide. This reaction is catalyzed by a copper salt such as copper(I) iodide and a chelator such as 8-hydroxyquinoline, both present in about 0.05 to about 0.25 equivalents, at a temperature ranging between about 80° C. and about 140° C., to form the 1-aryl-3-(4-bromophenyl) triazole (4-4, step b).
Molecules of Formula One wherein L is a one-carbon linker, can be prepared from acid or amine intermediates described in Scheme 5 and Scheme 6, respectively. Acid precursors Ar1-Het-Ar2-L-CO2H, unsubstituted or mono- or di-substituted with R8; can be prepared as shown in the Scheme 5. Boronic esters (5-2, step a) can be prepared using Miyaura conditions from halophenyl esters (5-1). Coupling of the boronate esters with a bromo-heterocycle (5-3, step b) can be accomplished using a palladium catalyst and phosphine ligand, in the presence of a base, such as sodium bicarbonate, potassium phosphate, or cesium fluoride, in a suitable solvent system, such as dioxane/water, at temperatures from about 50° C. to about 120° C. to form triaryl ester intermediates (5-4, step c). Among palladium catalysts, tetrakis(triphenylphosphine) palladium(0) is preferred, although other well-known palladium catalysts may be used. Saponification of the ester may be achieved by using a strong base such as sodium hydroxide or lithium hydroxide in methanol or ethanol with or without tetrahydrofuran/water to furnish the desired carboxylic acid (5-5, step c).
Amine precursors Ar1-Het-Ar2-L-NH2, unsubstituted or mono- or di-substituted with R8, can be prepared as shown in the Scheme 6. Halobenzyl amines (6-1) may be protected using benzyl chloroformate in the presence of a base such as triethylamine in an aprotic solvent such as dichloromethane at about −10° C. to about 10° C. to provide N-carboxybenzyl (Cbz) protected benzyl amines (6-2, step a). Alternatively, other N-protecting groups such as tert-butoxycarbonyl (BOC) or 9-fluorenylmethylcarbonyl (Fmoc) may be employed in step a using similar conditions described above for Cbz. The Cbz protected boronic ester 6-3 can be prepared using Miyaura conditions (step b). Coupling of the boronate esters with a bromo-heterocycle (5-3) can be accomplished using a palladium catalyst and phosphine ligand, in the presence of a base, such as sodium bicarbonate, potassium phosphate, or cesium fluoride, in a suitable solvent system, such as dioxane/water, at temperatures from about 50° C. to about 120° C. to form N-protected aminoalkylphenyl intermediates (6-4, step c). Deprotection of the Cbz group can be accomplished under acidic conditions with a strong acid such as hydrogen bromide, followed by free basing with a base such as sodium bicarbonate or sodium hydroxide, to furnish the free amine precursors Ar1-Het-Ar2-L-NH2 (6-5, step d). Similar methods could be applied to compounds wherein L is greater than 1-carbon.
Preparation of Ethyl Linked Intermediates Preparation of compounds wherein L is a two-atom group is described in Schemes 7 to Schemes 9. Condensation of the aldehyde (7-1, R9═H) (described in US 2012/0202688 A1) with reagents such as ethyl diethylphosphonoacetate or a Wittig reagent such as ethyl 2-(triphenylphosphoranylidene)propanoate) or α-substituted acetates such as ethyl 2-fluoroacetate or ethyl 2-cyanoacetate in the presence of a suitable base such as sodium hydride or n-butyl lithium in aprotic solvents such as tetrahydrofuran or diethyl ether at temperatures from about −78° C. to about 20° C. can be used to prepare acrylic esters (7-2, step a) unsubstituted or mono-substituted with R9 and R10. Saponification of the resultant ester may be achieved by using a strong base such as sodium hydroxide in methanol or ethanol with or without tetrahydrofuran/water to furnish the vinyl carboxylic acid (7-3, step b). In some cases the partial condensation of aldehyde (7-1, R9═H) may result in the isolation of the alcohol intermediate (7-4, step c) especially when R10 is electron withdrawing. Substitution of this alcohol with nucleophilic reagents such as Deoxo-Fluor® (step d) followed by saponification as described above (step e) can generate highly substituted ethyl carboxylic acids (7-5) additionally substituted with R11, wherein R11 is defined as R8 above. When the saturated linkage is preferred, the acrylate ester (7-2) can be converted to the corresponding cyclopropane (7-6, step f) unsubstituted or mono- or di-substituted with R12; with sulfur ylides such as those formed in situ from trimethyl sulfonium iodide in the presence of an inorganic base such as sodium hydride in a polar aprotic solvent such as dimethyl sulfoxide or tetrahydrofuran. Likewise the acrylate ester (7-2) can be reduced to the parent alkane (7-8, step h) using hydrogen gas and a palladium catalyst. Both the cyclopropane and the alkane can be hydrolyzed under basic conditions described above to generate the free carboxylic acids 7-7 (step g) and 7-9 (step i), respectively.
In a similar manner, condensation of the ketone (7-1, R9=Alkyl) (described in WO 2011017504 A1) with either ethyl diethylphosphonoacetate or a Wittig reagent such as ethyl 2-(triphenylphosphoranylidene)propanoate or α-substituted alkyl esters such as ethyl 2-fluoroacetate or ethyl 2-cyanoacetate under similar conditions described above may generate the α-alkyl acrylate esters 7-2 or alcohols 7-4. Subsequent treatment of 7-2 or 7-4 as described above for R9═H may lead to either the corresponding unsaturated (7-3) or saturated (7-5, 7-7, 7-9) carboxylic acids.
Alternatively, compounds wherein L is a 2-carbon linker may also be prepared as shown in Scheme 8. Using conditions first described by Molander et al. Org. Lett., 2007, 9 (2), pp 203-206, coupling of a bromide Ar1-Het-Ar2—Br (8-1, step a), with potassium (2-((tert-butoxycarbonyl)amino)ethyl)trifluoroborate in the presence of a palladium catalyst such as palladium(II) acetate, and a base such as cesium carbonate, at temperatures from about 80° C. to about 120° C., results in the formation of the corresponding 2-(tert-butoxycarbonyl)amino)ethyl derivative 8-2. Further treatment of this material with from about 1 to about 5 equivalents of an acid such as trifluoroacetic acid or hydrogen chloride, in an aprotic solvent such as dichloromethane or dioxane at temperatures from about 0° C. to about 50° C., results in the cleavage of the tert-butoxycarbonyl group and formation of the trifluoroacetic acid salt of the amine Ar1-Het-Ar2-L-NH2 (8-3, step b).
Aminoalkyl precursors Ar1-Het-Ar2-L-NH2, wherein L is 2-carbon atoms, mono- or di-substituted with R9, wherein R9 is defined as above; and unsubstituted or mono-substituted with R10, wherein R10 is defined as above, can be prepared as shown in Scheme 9. Halophenyl carbinols 9-1, wherein X can be selected from Cl, Br, or I, unsubstituted at R9 and R10 are available commercially. Carbinols 9-1 that are mono- or di-substituted at R9 can be prepared from the corresponding halophenyl acetate (9-1, step a) in similar fashion to that described by Shin et al. Bioorg. Med. Chem. Lett., 2008, 18, pp 4424-4427 followed by reduction with a metal hydride such as lithium aluminum hydride in an ethereal solvent such as tetrahydrofuran or diethyl ether at temperatures at or below about 0° C. Both 9-1 and 9-11 may be further mono-substituted (step b or step c) with R10 via reduction to the corresponding aldehyde with a metal hydride such as diisobutylaluminum hydride and further treatment with a Grignard reagent in a similar fashion to that described by Brimble et al. Org. Lett., 2012, 14 (23), pp 5820-5823. Carbinols 9-1 can be treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 9-2 (step d). The halide can be converted into a boronic ester under Miyaura conditions to form boronate esters (9-3, step e). Coupling of the boronate esters with a bromo-heterocycle can be accomplished using a palladium catalyst, such tetrakis(triphenylphosphine) palladium(0), in the presence of a base, such as sodium bicarbonate, in a suitable solvent system, such as dioxane/water, at temperatures from about 50° C. to about 120° C. to provide N-phthalimido intermediates 9-4 (step f). Deprotection using hydrazine and methanol or other suitable solvent can furnish the amine 9-5 (step g).
Alternatively, compounds wherein L is a 2-atom linker may also be prepared as shown in Scheme 9a. Olefination of aldehyde (7-1, R9═H, step a) may be achieved with methylenetriphenylphosphorane which can be prepared from methyl triphenylphosphonium iodide in the presence of a base such as sodium hydride or 1,8-diazabicycloundec-7-ene in an aprotic solvent such as tetrahydrofuran or dichloromethane at temperatures of about −78° C. to about 40° C. Further treatment of this material (9-2a) with a hydroborating reagent such as 9-borabicyclo(3.3.1)nonane in an aprotic solvent such as tetrahydrofuran followed by oxidation with an oxidant such as hydrogen peroxide can generate ethyl alcohol 9-3a (step b). Carbinols 9-3a can be treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 9-5a (step c), wherein R10═H. Deprotection using hydrazine and methanol or other suitable solvent can furnish the amine 9-6a (step f). Additionally, 9-3a may be further mono-substituted (step d) with R10, wherein R10 is defined as above, via oxidation to the corresponding aldehyde under Swern conditions followed by addition of a Grignard reagent such as described above (Scheme 9). Carbinols 9-4a can be further treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 9-5a (step e). Deprotection using hydrazine and methanol or other suitable solvent can furnish the amine 9-6a (step f).
Scheme 9b outlines an alternative route for constructing analogs wherein the linker L is a two-atom linker. Copper-catalyzed arylation of 2,4-pantane-2,4-dione with 8-1 (JACS, 2010, 132, 8273.) may provide the substituted acetone intermediate 9-1b (step a). Reductive amination (step b), using any of a variety of conditions familiar to those skilled in the art, may generate amine 9-2b, which may be converted into the target molecules using conditions described previously in Scheme 2. When a linker contains a chiral center, such as with intermediate 9-2b, these intermediates may be separated into their pure isomeric forms either by means of a chiral column, or by fractional crystallization of the salt prepared from a chiral acid such as (+) and (−) tartaric acid.
Construction of analogs wherein the ethyl linking group is part of a 6-membered ring is may also be accomplished starting from bromide 8-1. Coupling of 8-1 with 2-cyclohex-1-enyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (Scheme 9b, step c) under standard Suzuki coupling conditions can lead to alkene 9-3b. Epoxidation with standard reagents, such as meta-chloroperoxybenzoic acid (step d), followed by acid-catalyzed rearrangement using indium trichloride (J.Org.Chem. 1998, 63(23), 8212.) may generates ketone 9-5b. Reductive amination and conversion into the target molecules can be accomplished using conditions described above.
Preparation of compounds wherein L is a three-atom group is described in Schemes 10 and 11. Aminoalkyl precursors Ar1-Het-Ar2-L-NH2, wherein L is 3-carbon atoms, mono- or di-substituted with R9, wherein R9 is defined as above; and unsubstituted or mono-substituted with R10, wherein R10 is defined as above; can be prepared as shown in Scheme 10. Halophenyl carbinol 10-1, wherein X is Br and R9 and R10 are H, is available commercially. Carbinols 10-1 that are mono- or di-substituted at R9 can be prepared from the corresponding halophenyl acetate (10-I, step a) in similar fashion to that described by Shin et al. Bioorg. Med. Chem. Lett., 2008, 18, pp 4424-4427, followed by reduction with a metal hydride such as lithium aluminum hydride in an ethereal solvent such as tetrahydrofuran at temperatures at or below about 0° C. Both 10-I and 10-II may be further mono-substituted (step b or step c) with R10 via reduction to the corresponding aldehyde with a metal hydride such as diisobutylaluminum hydride and further treatment with a Grignard reagent such as methylmagnesium bromide in a similar fashion to that described by Brimble et al. Org. Lett., 2012, 14 (23), pp 5820-5823; Carbinols 10-1 can be treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 10-2 (step d).
The halide can be converted into boronic ester under Miyaura conditions to form boronate esters (10-3, step e). Coupling of the boronate esters with a bromo-heterocycle can be accomplished using a palladium catalyst, such tetrakis(triphenylphosphine) palladium(0), in the presence of a base, such as sodium bicarbonate, in a suitable solvent system, such as dioxane/water, at temperatures from about 50° C. to about 120° C. to provide N-phthalimido intermediates 10-4 (step f). Deprotection using hydrazine and methanol or other suitable solvent can furnish the amine 10-5 (step g).
Alternatively, compounds wherein L is a 3-atom linker may also be prepared as shown in Scheme 11. Bromide Ar1-Het-Ar2—Br (8-1) can be coupled with an appropriate alkynyl alcohol (11-1, step a) unsubstituted or mono-substituted with R10, wherein R10 is defined as above; in the presence of a palladium catalyst such as bistriphenylphosphine dichloropalladium(II), copper(I) iodide, and a base such as triethylamine, at temperatures from about 50° C. to about 120° C., to generate the corresponding alkynyl alcohol derivatives 11-2. The resultant carbinols 11-2 can be treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 11-3 (step b) which can be converted to amine (11-7, step e) using hydrazine and methanol or other suitable solvent. Carbinols 11-2 can be reduced using a transition metal catalyst, such as palladium under an atmosphere of hydrogen to provide alkenyl or fully saturated alkyl carbinols 11-4 unsubstituted at R10. Additionally, carbinols 11-2 can be treated with a metal hydride such as lithium aluminum hydride to provide the (E)-alkenyl carbinol 11-4. Likewise, carbinol 11-2 may be protected with a protecting group such as tert-butyl diphenyl silane, and treated with a hydrometallation reagent such as Schwartz′ reagent followed by an electrophile quench, with, for example, elemental iodine or NBS. Alternatively, the carbinol 11-2 may be treated with a transmetallation reagent such as pinacol diboron for further use in transition metal-catalyzed coupling reactions, such as Suzuki or Negishi, to prepare carbinols 11-4 mono- or di-substituted with R9, wherein R9 is defined as above (step c). Following deprotection, the resultant carbinols 11-4 can be treated with phthalimide under Mitsunobu conditions to generate N-phthalimido intermediates 11-5 (step d) which can be converted to an amine (11-6, step e) using hydrazine and methanol or other suitable solvent.
Compounds wherein L is a 4-atom linker may be prepared as shown in Scheme 12. Bromide Ar1-Het-Ar2—Br (8-1) can be coupled with an appropriate alkynyl alcohol (12-1, step a) unsubstituted or mono-substituted with R10, wherein R10 is defined as above; mono- or di-substituted with R9, wherein R9 is defined as above; in the presence of a palladium catalyst such as bistriphenylphosphine dichloropalladium, copper(I) iodide, and a base such as triethylamine, at temperatures from about 50° C. to about 120° C., to generate the corresponding alkynyl alcohol derivatives 12-2. The resultant carbinols 12-2 can be treated with phthalimide under Mitsunobu conditions (step b) to generate N-phthalimido intermediates 12-3 which can be converted to an amine (12-7, step e) using hydrazine and methanol or other suitable solvents. Carbinols 12-2 can be reduced using a transition metal catalyst, such as palladium under an atmosphere of hydrogen to provide alkenyl or fully saturated alkyl carbinols 12-4 (step c) unsubstituted at R13. Additionally, carbinols 12-2 can be treated with a metal hydride such as lithium aluminum hydride to provide the (E)-alkenyl carbinols 12-4 (step c). Likewise, carbinol 12-2 may be protected with a protecting group such as tert-butyl diphenyl silane, and treated with a hydrometallation reagent such as Schwartz′ reagent followed by an electrophile quench, with, for example, elemental iodine or NBS. Alternatively the carbinol 12-2 may be treated with a transmetallation reagent such as pinacol diboron for further use in transition metal-catalyzed coupling reactions, such as Suzuki or Negishi, to prepare carbinols 12-4 mono- or di-substituted with R13, wherein R13 is defined as R8 above (step c).
Following deprotection, the resultant carbinols 12-4 can be treated with phthalimide under Mitsunobu conditions (step d) to generate N-phthalimido intermediates 12-5 which can be converted to an amine (12-6, step e) using hydrazine and methanol or other suitable solvent.
2-Imino 1,3-thiazolin-4-ones (3-1) may be further functionalized using a variety of conditions. When treated with Selectfluor® and 9-fluorenone in anhydrous acetonitrile (JACS. 2013, 135, 17494.), molecules having the formula 3-1 may be converted into the mono-fluoro analogs (13-1).
Treatment with molecular bromine in a non-protic solvent such as dichloromethane at from about 0° C. to about 30° C. (step b) may result in mono-bromination on the thiazolinone ring (13-2). Alkylation (step c), using at least 2 equivalents of an alkylating agent R5—I and a strong base such as sodium hydride or lithium diisopropylamide in a polar aprotic solvent such as dimethylformamide or tetrahydrofuran may lead to a di-alkylated product (13-3). Treatment with a ketone or an aldehyde and an inorganic base such as potassium carbonate or cesium carbonate may result in the formation of a carbinol (13-4). For analogs of compounds of the formula 3-1 wherein L is a —CH2CH2— group, free-radical bromination using N-bromosuccinimide and a free radical initiator such as azobis (isobutyronitrile) in carbon tetrachloride at about 30° C. to about 77° C. may lead to the mono-brominated product (13-5) wherein the bromine is incorporated into the ethyl linker.

Using the procedures disclosed herein, molecules having a structure according to Formula One have been disclosed in Tables P-One and P-Two of U.S. Pat. Nos. 9,029,560, 9,249,133, 9,278,964, and/or 9,783,532, where molecules/compounds of Tables P-One and P-Two are expressly incorporated by reference herein.
BAW has few effective parasites, diseases, or predators to lower its population. BAW infests many weeds, trees, grasses, legumes, and field crops. In various places, it is of economic concern upon asparagus, cotton, corn, soybeans, tobacco, alfalfa, sugar beets, peppers, tomatoes, potatoes, onions, peas, sunflowers, and citrus, among other plants. The Cabbage Looper is a member of the moth family Noctuidae. It is found throughout the world. It is attacks cabbage, cauliflower, broccoli, Brussel sprouts, tomatoes, cucumbers, potatoes, kale, turnips, mustard, peppers, eggplant, watermelons, melons, squash, cantaloupe, peas, beans, collards, lettuce, spinach, celery, parsley, beets, peas, alfalfa, soybeans, and cotton. This species is very destructive to plants due to its voracious consumption of leaves. In the case of cabbage, however, they feed not only on the wrapper leaves, but also may bore into the developing head. The larvae consume three times their weight in plant material daily. The feeding sites are marked by large accumulations of sticky, wet fecal material.
Consequently, because of the above factors control of these pests is important. Furthermore, molecules that control these pests (BAW and CL), which are known as chewing pests, are useful in controlling other pests that chew on plants.
Certain molecules disclosed in this document were tested against BAW and CEW using procedures described in the following examples. In the reporting of the results, the “BAW & CL Rating Table” was used (See Table Section).
Bioassays on BAW were conducted using a 128-well diet tray assay. one to five second instar BAW larvae were placed in each well (3 mL) of the diet tray that had been previously filled with 1 mL of artificial diet to which 50 μg/cm2 of the test compound (dissolved in 50 μL of 90:10 acetone-water mixture) had been applied (to each of eight wells) and then allowed to dry. Trays were covered with a clear self-adhesive cover and held at 25° C., 14:10 light-dark for five to seven days. Percent mortality was recorded for the larvae in each well; activity in the eight wells was then averaged. The results are indicated in the table entitled “Table ABC: Biological Results” (See Table Section).
Bioassays on CL were conducted using a 128-well diet tray assay. one to five second instar CL larvae were placed in each well (3 mL) of the diet tray that had been previously filled with 1 mL of artificial diet to which 50 g/cm2 of the test compound (dissolved in 50 μL of 90:10 acetone-water mixture) had been applied (to each of eight wells) and then allowed to dry. Trays were covered with a clear self-adhesive cover and held at 25° C., 14:10 light-dark for five to seven days. Percent mortality was recorded for the larvae in each well; activity in the eight wells was then averaged. The results are indicated in the table entitled “Table ABC: Biological Results” (See Table Section).
GPA is the most significant aphid pest of peach trees, causing decreased growth, shriveling of the leaves, and the death of various tissues. It is also hazardous because it acts as a vector for the transport of plant viruses, such as potato virus Y and potato leafroll virus to members of the nightshade/potato family Solanaceae, and various mosaic viruses to many other food crops. GPA attacks such plants as broccoli, burdock, cabbage, carrot, cauliflower, daikon, eggplant, green beans, lettuce, macadamia, papaya, peppers, sweet potatoes, tomatoes, watercress, and zucchini, among other plants. GPA also attacks many ornamental crops such as carnation, chrysanthemum, flowering white cabbage, poinsettia, and roses. GPA has developed resistance to many pesticides. Consequently, because of the above factors control of this pest is important. Furthermore, molecules that control this pest (GPA), which is known as a sucking pest, are useful in controlling other pests that suck on plants.
Certain molecules disclosed in this document were tested against GPA using procedures described in the following example. In the reporting of the results, the “GPA Rating Table” was used (See Table Section).
Cabbage seedlings grown in 3-inch pots, with 2-3 small (3-5 cm) true leaves, were used as test substrate. The seedlings were infested with 20-50 GPA (wingless adult and nymph stages) one day prior to chemical application. Four pots with individual seedlings were used for each treatment. Test compounds (2 mg) were dissolved in 2 mL of acetone/methanol (1:1) solvent, forming stock solutions of 1000 ppm test compound. The stock solutions were diluted 5× with 0.025% Tween 20 in water to obtain the solution at 200 ppm test compound. A hand-held aspirator-type sprayer was used for spraying a solution to both sides of cabbage leaves until runoff. Reference plants (solvent check) were sprayed with the diluent only containing 20% by volume of acetone/methanol (1:1) solvent. Treated plants were held in a holding room for three days at approximately 25° C. and ambient relative humidity (RH) prior to grading. Evaluation was conducted by counting the number of live aphids per plant under a microscope. Percent Control was measured by using Abbott's correction formula (W. S. Abbott, “A Method of Computing the Effectiveness of an Insecticide” J. Econ. Entomol. 18 (1925), pp. 265-267) as follows.
Corrected % Control=100*(X−Y)/X
The results are indicated in the table entitled “Table ABC: Biological Results” (See Table Section).
YFM prefers to feed on humans during the daytime and is most frequently found in or near human habitations. YFM is a vector for transmitting several diseases. It is a mosquito that can spread the dengue fever and yellow fever viruses. Yellow fever is the second most dangerous mosquito-borne disease after malaria. Yellow fever is an acute viral hemorrhagic disease and up to 50% of severely affected persons without treatment will die from yellow fever. There are an estimated 200,000 cases of yellow fever, causing 30,000 deaths, worldwide each year. Dengue fever is a nasty, viral disease; it is sometimes called “breakbone fever” or “break-heart fever” because of the intense pain it can produce. Dengue fever kills about 20,000 people annually. Consequently, because of the above factors control of this pest is important. Furthermore, molecules that control this pest (YFM), which is known as a sucking pest, are useful in controlling other pests that cause human and animal suffering.
Certain molecules disclosed in this document were tested against YFM using procedures described in the following paragraph. In the reporting of the results, the “YFM Rating Table” was used (See Table Section).
Master plates containing 400 μg of a molecule dissolved in 100 μL of dimethyl sulfoxide (DMSO) (equivalent to a 4000 ppm solution) are used. A master plate of assembled molecules contains 15 μL per well. To this plate, 135 μL of a 90:10 water:acetone mixture is added to each well. A robot (Biomek® NXP Laboratory Automation Workstation) is programmed to dispense 15 μL aspirations from the master plate into an empty 96-well shallow plate (“daughter” plate). There are 6 reps (“daughter” plates) created per master. The created daughter plates are then immediately infested with YFM larvae.
The day before plates are to be treated, mosquito eggs are placed in Millipore water containing liver powder to begin hatching (4 g. into 400 mL). After the daughter plates are created using the robot, they are infested with 220 L of the liver powder/larval mosquito mixture (about 1 day-old larvae). After plates are infested with mosquito larvae, a non-evaporative lid is used to cover the plate to reduce drying. Plates are held at room temperature for 3 days prior to grading. After 3 days, each well is observed and scored based on mortality.
The results are indicated in the table entitled “Table ABC: Biological Results” (See Table Section).
Molecules of Formula One may be formulated into agriculturally acceptable acid addition salts. By way of a non-limiting example, an amine function can form salts with hydrochloric, hydrobromic, sulfuric, phosphoric, acetic, benzoic, citric, malonic, salicylic, malic, fumaric, oxalic, succinic, tartaric, lactic, gluconic, ascorbic, maleic, aspartic, benzenesulfonic, methanesulfonic, ethanesulfonic, hydroxyl-methanesulfonic, and hydroxyethanesulfonic acids. Additionally, by way of a non-limiting example, an acid function can form salts including those derived from alkali or alkaline earth metals and those derived from ammonia and amines. Examples of preferred cations include sodium, potassium, and magnesium.
Molecules of Formula One may be formulated into salt derivatives. By way of a non-limiting example, a salt derivative can be prepared by contacting a free base with a sufficient amount of the desired acid to produce a salt. A free base may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium hydroxide, potassium carbonate, ammonia, and sodium bicarbonate. As an example, in many cases, a pesticide, such as 2,4-D, is made more water-soluble by converting it to its dimethylamine salt.
Molecules of Formula One may be formulated into stable complexes with a solvent, such that the complex remains intact after the non-complexed solvent is removed. These complexes are often referred to as “solvates.” However, it is particularly desirable to form stable hydrates with water as the solvent.
Molecules of Formula One may be made into ester derivatives. These ester derivatives can then be applied in the same manner as the molecules disclosed in this document is applied.
Molecules of Formula One may be made as various crystal polymorphs. Polymorphism is important in the development of agrochemicals since different crystal polymorphs or structures of the same molecule can have vastly different physical properties and biological performances.
Molecules of Formula One may be made with different isotopes. Of particular importance are molecules having 2H (also known as deuterium) in place of 1H.
Molecules of Formula One may be made with different radionuclides. Of particular importance are molecules having 14C.
Molecules of Formula One may exist as one or more stereoisomers. Thus, certain molecules can be produced as racemic mixtures. It will be appreciated by those skilled in the art that one stereoisomer may be more active than the other stereoisomers. Individual stereoisomers may be obtained by known selective synthetic procedures, by conventional synthetic procedures using resolved starting materials, or by conventional resolution procedures. Certain molecules disclosed in this document can exist as two or more isomers. The various isomers include geometric isomers, diastereomers, and enantiomers. Thus, the molecules disclosed in this document include geometric isomers, racemic mixtures, individual stereoisomers, and optically active mixtures. It will be appreciated by those skilled in the art that one isomer may be more active than the others. The structures disclosed in the present disclosure are drawn in only one geometric form for clarity, but are intended to represent all geometric forms of the molecule.
In another embodiment, molecules of Formula One may be used in combination (such as, in a compositional mixture, or a simultaneous or sequential application) with one or more compounds each having a mode of action that is the same as, similar to, or different from, the mode of action (“MoA”) of the molecules of Formula One. Modes of action include, for example the following: Acetylcholinesterase (AChE) inhibitors; GABA-gated chloride channel antagonists; Sodium channel modulators; Nicotinic acetylcholine (nAChR) agonists; Nicotinic acetylcholine receptor (nAChR) allosteric activators; Chloride channel activators; Juvenile hormone mimics; Miscellaneous non-specific (multi-site) inhibitors; Selective homopteran feeding blockers; Mite growth inhibitors; Microbial disruptors of insect midgut membranes; Inhibitors of mitochondrial ATP synthase; Uncouplers of oxidative phosphorylation via disruption of the proton gradient; Nicotinic acetylcholine receptor (nAChR) channel blockers; Inhibitors of chitin biosynthesis, type 0; Inhibitors of chitin biosynthesis, type 1; Moulting disruptor, Dipteran; Ecdysone receptor agonists; Octopamine receptor agonists; Mitochondrial complex III electron transport inhibitors; Mitochondrial complex I electron transport inhibitors; Voltage-dependent sodium channel blockers; Inhibitors of acetyl CoA carboxylase; Mitochondrial complex IV electron transport inhibitors; Mitochondrial complex II electron transport inhibitors; and Ryanodine receptor modulators.
In another embodiment, molecules of Formula One may be used in combination (such as, in a compositional mixture, or a simultaneous or sequential application) with one or more compounds having acaricidal, algicidal, avicidal, bactericidal, fungicidal, herbicidal, insecticidal, molluscicidal, nematicidal, rodenticidal, and/or virucidal properties.
In another embodiment, the molecules of Formula One may be used in combination (such as, in a compositional mixture, or a simultaneous or sequential application) with one or more compounds that are antifeedants, bird repellents, chemosterilants, herbicide safeners, insect attractants, insect repellents, mammal repellents, mating disrupters, plant activators, plant growth regulators, and/or synergists.

In another embodiment, molecules of Formula One may also be used in combination (such as in a compositional mixture, or a simultaneous or sequential application) with one or more biopesticides. The term “biopesticide” is used for microbial biological pest control agents that are applied in a similar manner to chemical pesticides. Commonly these are bacterial, but there are also examples of fungal control agents, including Trichoderma spp. and Ampelomyces quisqualis (a control agent for grape powdery mildew). Bacillus subtilis are used to control plant pathogens. Weeds and rodents have also been controlled with microbial agents. One well-known insecticide example is Bacillus thuringiensis, a bacterial disease of Lepidoptera, Coleoptera, and Diptera. Because it has little effect on other organisms, it is considered more environmentally friendly than synthetic pesticides. Biological insecticides include products based on: entomopathogenic fungi (e.g. Metarhizium anisopliae); entomopathogenic nematodes (e.g. Steinernema feltiae); and entomopathogenic viruses (e.g. Cydia pomonella granulovirus).
Other examples of entomopathogenic organisms include, but are not limited to, baculoviruses, bacteria and other prokaryotic organisms, fungi, protozoa and Microsproridia. Biologically derived insecticides include, but not limited to, rotenone, veratridine, as well as microbial toxins; insect tolerant or resistant plant varieties; and organisms modified by recombinant DNA technology to either produce insecticides or to convey an insect resistant property to the genetically modified organism. In one embodiment, the molecules of Formula One may be used with one or more biopesticides in the area of seed treatments and soil amendments. The Manual of Biocontrol Agents gives a review of the available biological insecticide (and other biology-based control) products. Copping L. G. (ed.) (2004). The Manual of Biocontrol Agents (formerly the Biopesticide Manual) 3rd Edition. British Crop Production Council (BCPC), Farnham, Surrey UK.
In another embodiment, the above possible combinations may be used in a wide variety of weight ratios. For example, a two component mixture, the weight ratio of a molecule of Formula One to another compound, can be from about 100:1 to about 1:100; in another example the weight ratio can be about 50:1 to about 1:50; in another example the weight ratio can be about 20:1 to about 1 to 20; in another example the weight ratio can be about 10:1 to about 1:10; in another example the weight ratio can be about 5:1 to 1:5; in another example the weight ratio can be about 3:1 to about 1:3; and in a final example the weight ratio can be about 1:1. However, preferably, weight ratios less than about 10:1 to about 1:10 are preferred. It is also preferred sometimes to use a three or four component mixture comprising one or more molecules of Formula One and one or more other compounds from the above possible combinations.
A pesticide is rarely suitable for application in its pure form. It is usually necessary to add other substances so that the pesticide can be used at the required concentration and in an appropriate form, permitting ease of application, handling, transportation, storage, and maximum pesticide activity. Thus, pesticides are formulated into, for example, baits, concentrated emulsions, dusts, emulsifiable concentrates, fumigants, gels, granules, microencapsulations, seed treatments, suspension concentrates, suspoemulsions, tablets, water soluble liquids, water dispersible granules or dry flowables, wettable powders, and ultra-low volume solutions. For further information on formulation types see “Catalogue of Pesticide Formulation Types and International Coding System” Technical Monograph n° 2, 5th Edition by CropLife International (2002).
Pesticides are applied most often as aqueous suspensions or emulsions prepared from concentrated formulations of such pesticides. Such water-soluble, water-suspendable, or emulsifiable formulations are either solids, usually known as wettable powders, or water dispersible granules, or liquids usually known as emulsifiable concentrates, or aqueous suspensions. Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of the pesticide, a carrier, and surfactants. The concentration of the pesticide is usually from about 10% to about 90% by weight. The carrier is usually selected from among the attapulgite clays, the montmorillonite clays, the diatomaceous earths, or the purified silicates. Effective surfactants, comprising from about 0.5% to about 10% of the wettable powder, are found among sulfonated lignins, condensed naphthalenesulfonates, naphthalenesulfonates, alkylbenzenesulfonates, alkyl sulfates, and non-ionic surfactants such as ethylene oxide adducts of alkyl phenols.
Emulsifiable concentrates of pesticides comprise a convenient concentration of a pesticide, such as from about 50 to about 500 grams per liter of liquid dissolved in a carrier that is either a water miscible solvent or a mixture of water-immiscible organic solvent and emulsifiers. Useful organic solvents include aromatics, especially xylenes and petroleum fractions, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as the terpenic solvents including rosin derivatives, aliphatic ketones such as cyclohexanone, and complex alcohols such as 2-ethoxyethanol. Suitable emulsifiers for emulsifiable concentrates are selected from conventional anionic and non-ionic surfactants.
Aqueous suspensions comprise suspensions of water-insoluble pesticides dispersed in an aqueous carrier at a concentration in the range from about 5% to about 50% by weight. Suspensions are prepared by finely grinding the pesticide and vigorously mixing it into a carrier comprised of water and surfactants. Ingredients, such as inorganic salts and synthetic or natural gums may also be added, to increase the density and viscosity of the aqueous carrier. It is often most effective to grind and mix the pesticide 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.
Pesticides may also be applied as granular compositions that are particularly useful for applications to the soil. Granular compositions usually contain from about 0.5% to about 10% by weight of the pesticide, dispersed in a carrier that comprises clay or a similar substance. Such compositions are usually prepared by dissolving the pesticide in a suitable solvent and applying it to a granular carrier which has been pre-formed 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 size.
Dusts containing a pesticide are prepared by intimately mixing the pesticide in powdered form with a suitable dusty agricultural carrier, such as kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1% to about 10% of the pesticide. They can be applied as a seed dressing or as a foliage application with a dust blower machine.
It is equally practical to apply a pesticide in the form of a solution in an appropriate organic solvent, usually petroleum oil, such as the spray oils, which are widely used in agricultural chemistry.
Pesticides can also be applied in the form of an aerosol composition. In such compositions the pesticide is dissolved or dispersed in a carrier, which is a pressure-generating propellant mixture. The aerosol composition is packaged in a container from which the mixture is dispensed through an atomizing valve.
Pesticide baits are formed when the pesticide is mixed with food or an attractant or both. When the pests eat the bait they also consume the pesticide. Baits may take the form of granules, gels, flowable powders, liquids, or solids. They can be used in pest harborages.
Fumigants are pesticides that have a relatively high vapor pressure and hence can exist as a gas in sufficient concentrations to kill pests in soil or enclosed spaces. The toxicity of the fumigant is proportional to its concentration and the exposure time. They are characterized by a good capacity for diffusion and act by penetrating the pest's respiratory system or being absorbed through the pest's cuticle. Fumigants are applied to control stored product pests under gas proof sheets, in gas sealed rooms or buildings or in special chambers.
Pesticides can be microencapsulated by suspending the pesticide particles or droplets in plastic polymers of various types. By altering the chemistry of the polymer or by changing factors in the processing, microcapsules can be formed of various sizes, solubility, wall thicknesses, and degrees of penetrability. These factors govern the speed with which the active ingredient within is released, which in turn, affects the residual performance, speed of action, and odor of the product.
Oil solution concentrates are made by dissolving pesticide in a solvent that will hold the pesticide in solution. Oil solutions of a pesticide usually provide faster knockdown and kill of pests than other formulations due to the solvents themselves having pesticidal action and the dissolution of the waxy covering of the integument increasing the speed of uptake of the pesticide. Other advantages of oil solutions include better storage stability, better penetration of crevices, and better adhesion to greasy surfaces.
Another embodiment is an oil-in-water emulsion, wherein the emulsion comprises oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase, wherein each oily globule comprises at least one compound which is agriculturally active, and is individually coated with a monolamellar or oligolamellar layer comprising: (1) at least one non-ionic lipophilic surface-active agent, (2) at least one non-ionic hydrophilic surface-active agent and (3) at least one ionic surface-active agent, wherein the globules having a mean particle diameter of less than 800 nanometers. Further information on the embodiment is disclosed in U.S. patent publication 20070027034 published Feb. 1, 2007, having patent application Ser. No. 11/495,228. For ease of use, this embodiment will be referred to as “OIWE”.

Generally, when the molecules disclosed in Formula One are used in a formulation, such formulation can also contain other components. These components include, but are not limited to, (this is a non-exhaustive and non-mutually exclusive list) wetters, spreaders, stickers, penetrants, buffers, sequestering agents, drift reduction agents, compatibility agents, anti-foam agents, cleaning agents, and emulsifiers. A few components are described forthwith.
A wetting agent is a substance that when added to a liquid increases the spreading or penetration power of the liquid by reducing the interfacial tension between the liquid and the surface on which it is spreading. Wetting agents are used for two main functions in agrochemical formulations: during processing and manufacture to increase the rate of wetting of powders in water to make concentrates for soluble liquids or suspension concentrates; and during mixing of a product with water in a spray tank to reduce the wetting time of wettable powders and to improve the penetration of water into water-dispersible granules. Examples of wetting agents used in wettable powder, suspension concentrate, and water-dispersible granule formulations are: sodium lauryl sulfate; sodium dioctyl sulfosuccinate; alkyl phenol ethoxylates; and aliphatic alcohol ethoxylates.
A dispersing agent is a substance which adsorbs onto the surface of particles and helps to preserve the state of dispersion of the particles and prevents them from reaggregating. Dispersing agents are added to agrochemical formulations to facilitate dispersion and suspension during manufacture, and to ensure the particles redisperse into water in a spray tank. They are widely used in wettable powders, suspension concentrates and water-dispersible granules. Surfactants that are used as dispersing agents have the ability to adsorb strongly onto a particle surface and provide a charged or steric barrier to reaggregation of particles. The most commonly used surfactants are anionic, non-ionic, or mixtures of the two types. For wettable powder formulations, the most common dispersing agents are sodium lignosulfonates. For suspension concentrates, very good adsorption and stabilization are obtained using polyelectrolytes, such as sodium naphthalene sulfonate formaldehyde condensates. Tristyrylphenol ethoxylate phosphate esters are also used. Non-ionics such as alkylarylethylene oxide condensates and EO-PO block copolymers are sometimes combined with anionics as dispersing agents for suspension concentrates. In recent years, new types of very high molecular weight polymeric surfactants have been developed as dispersing agents. These have very long hydrophobic ‘backbones’ and a large number of ethylene oxide chains forming the ‘teeth’ of a ‘comb’ surfactant. These high molecular weight polymers can give very good long-term stability to suspension concentrates because the hydrophobic backbones have many anchoring points onto the particle surfaces. Examples of dispersing agents used in agrochemical formulations are: sodium lignosulfonates; sodium naphthalene sulfonate formaldehyde condensates; tristyrylphenol ethoxylate phosphate esters; aliphatic alcohol ethoxylates; alkyl ethoxylates; EO-PO block copolymers; and graft copolymers.
An emulsifying agent is a substance which stabilizes a suspension of droplets of one liquid phase in another liquid phase. Without the emulsifying agent the two liquids would separate into two immiscible liquid phases. The most commonly used emulsifier blends contain alkylphenol or aliphatic alcohol with twelve or more ethylene oxide units and the oil-soluble calcium salt of dodecylbenzenesulfonic acid. A range of hydrophile-lipophile balance (“HLB”) values from 8 to 18 will normally provide good stable emulsions. Emulsion stability can sometimes be improved by the addition of a small amount of an EO-PO block copolymer surfactant.
A solubilizing agent is a surfactant which will form micelles in water at concentrations above the critical micelle concentration. The micelles are then able to dissolve or solubilize water-insoluble materials inside the hydrophobic part of the micelle. The types of surfactants usually used for solubilization are non-ionics, sorbitan monooleates, sorbitan monooleate ethoxylates, and methyl oleate esters.
Surfactants are sometimes used, either alone or with other additives such as mineral or vegetable oils as adjuvants to spray-tank mixes to improve the biological performance of the pesticide on the target. The types of surfactants used for bioenhancement depend generally on the nature and mode of action of the pesticide. However, they are often non-ionics such as: alkyl ethoxylates; linear aliphatic alcohol ethoxylates; aliphatic amine ethoxylates.
A carrier or diluent in an agricultural formulation is a material added to the pesticide to give a product of the required strength. Carriers are usually materials with high absorptive capacities, while diluents are usually materials with low absorptive capacities. Carriers and diluents are used in the formulation of dusts, wettable powders, granules and water-dispersible granules.
Organic solvents are used mainly in the formulation of emulsifiable concentrates, oil-in-water emulsions, suspoemulsions, and ultra-low volume formulations, and to a lesser extent, granular formulations. Sometimes mixtures of solvents are used. The first main groups of solvents are aliphatic paraffinic oils such as kerosene or refined paraffins. The second main group (and the most common) comprises the aromatic solvents such as xylene and higher molecular weight fractions of C9 and C10 aromatic solvents. Chlorinated hydrocarbons are useful as cosolvents to prevent crystallization of pesticides when the formulation is emulsified into water. Alcohols are sometimes used as cosolvents to increase solvent power. Other solvents may include vegetable oils, seed oils, and esters of vegetable and seed oils.
Thickeners or gelling agents are used mainly in the formulation of suspension concentrates, emulsions and suspoemulsions to modify the rheology or flow properties of the liquid and to prevent separation and settling of the dispersed particles or droplets. Thickening, gelling, and anti-settling agents generally fall into two categories, namely water-insoluble particulates and water-soluble polymers. It is possible to produce suspension concentrate formulations using clays and silicas. Examples of these types of materials, include, but are not limited to, montmorillonite, bentonite, magnesium aluminum silicate, and attapulgite. Water-soluble polysaccharides have been used as thickening-gelling agents for many years. The types of polysaccharides most commonly used are natural extracts of seeds and seaweeds or are synthetic derivatives of cellulose. Examples of these types of materials include, but are not limited to, guar gum; locust bean gum; carrageenam; alginates; methyl cellulose; sodium carboxymethyl cellulose (SCMC); hydroxyethyl cellulose (HEC). Other types of anti-settling agents are based on modified starches, polyacrylates, polyvinyl alcohol and polyethylene oxide. Another good anti-settling agent is xanthan gum.
Microorganisms can cause spoilage of formulated products. Therefore preservation agents are used to eliminate or reduce their effect. Examples of such agents include, but are not limited to: propionic acid and its sodium salt; sorbic acid and its sodium or potassium salts; benzoic acid and its sodium salt; p-hydroxybenzoic acid sodium salt; methyl p-hydroxybenzoate; and 1,2-benzisothiazolin-3-one (BIT).
The presence of surfactants often causes water-based formulations to foam during mixing operations in production and in application through a spray tank. In order to reduce the tendency to foam, anti-foam agents are often added either during the production stage or before filling into bottles. Generally, there are two types of anti-foam agents, namely silicones and non-silicones. Silicones are usually aqueous emulsions of dimethyl polysiloxane, while the non-silicone anti-foam agents are water-insoluble oils, such as octanol and nonanol, or silica. In both cases, the function of the anti-foam agent is to displace the surfactant from the air-water interface.
“Green” agents (e.g., adjuvants, surfactants, solvents) can reduce the overall environmental footprint of crop protection formulations. Green agents are biodegradable and generally derived from natural and/or sustainable sources, e.g. plant and animal sources. Specific examples are: vegetable oils, seed oils, and esters thereof, also alkoxylated alkyl polyglucosides.

Controlling pests of Phyla Nematoda, Arthropoda, and/or Mollusca generally means that pest populations, pest activity, or both, are reduced in an locus. This can come about when:
(a) pest populations are repulsed from a locus;
(b) pests are incapacitated in, or around, a locus; or
(c) pests are exterminated in, or around, a locus.
Of course, a combination of these results can occur. Generally, pest populations, activity, or both are desirably reduced more than fifty percent, preferably more than 90 percent, and most preferably more than 98 percent. Generally, the locus is not in, or on, a human; consequently, the locus is generally a non-human locus.
In another embodiment, the locus to which a molecule of Formula One is applied can be any locus that is inhabited, or that may become inhabited, or that may be traversed, by a pest of Phyla Nematoda, Arthropoda, and/or Mollusca. For example, the locus can be:
(a) where crops, trees, fruits, cereals, fodder species, vines, turf, and/or ornamental plants, are growing;
(b) where domesticated animals are residing;
(c) the interior or exterior surfaces of buildings (such as places where grains are stored);
(d) the materials of construction used in buildings (such as impregnated wood); and
(e) the soil around buildings.
Particular crop areas to use a molecule of Formula One include areas where apples, corn, sunflowers, cotton, soybeans, canola, wheat, rice, sorghum, barley, oats, potatoes, oranges, alfalfa, lettuce, strawberries, tomatoes, peppers, crucifers, pears, tobacco, almonds, sugar beets, beans and other valuable crops are growing or the seeds thereof are going to be planted. It is also advantageous to use ammonium sulfate with a molecule of Formula One when growing various plants.
In another embodiment, molecules of Formula One are generally used in amounts from about 0.0001 grams per hectare to about 5000 grams per hectare to provide control. In another embodiment, it is preferred that molecules of Formula One are used in amounts from about 0.001 grams per hectare to about 500 grams per hectare. In another embodiment, it is more preferred that molecules of Formula One are used in amounts from about 0.01 gram per hectare to about 50 grams per hectare.
The molecules of Formula One may be used in mixtures, applied simultaneously or sequentially, alone or with other compounds to enhance plant vigor (e.g. to grow a better root system, to better withstand stressful growing conditions). Such other compounds are, for example, compounds that modulate plant ethylene receptors, most notably 1-methylcyclopropene (also known as 1-MCP). Furthermore, such molecules may be used during times when pest activity is low, such as before the plants that are growing begin to produce valuable agricultural commodities. Such times include the early planting season when pest pressure is usually low.
The molecules of Formula One can be applied to the foliar and fruiting portions of plants to control pests. The molecules will either come in direct contact with the pest, or the pest will consume the pesticide when eating leaf, fruit mass, or extracting sap, that contains the pesticide. The molecules of Formula One can also be applied to the soil, and when applied in this manner, root and stem feeding pests can be controlled. The roots can absorb a molecule taking it up into the foliar portions of the plant to control above ground chewing and sap feeding pests.
Generally, with baits, the baits are placed in the ground where, for example, termites can come into contact with, and/or be attracted to, the bait. Baits can also be applied to a surface of a building, (horizontal, vertical, or slant surface) where, for example, ants, termites, cockroaches, and flies, can come into contact with, and/or be attracted to, the bait. Baits can comprise a molecule of Formula One.
The molecules of Formula One can be encapsulated inside, or placed on the surface of a capsule. The size of the capsules can range from nanometer size (about 100-900 nanometers in diameter) to micrometer size (about 10-900 microns in diameter).
Because of the unique ability of the eggs of some pests to resist certain pesticides, repeated applications of the molecules of Formula One may be desirable to control newly emerged larvae.
Systemic movement of pesticides in plants may be utilized to control pests on one portion of the plant by applying (for example by spraying an area) the molecules of Formula One to a different portion of the plant. For example, control of foliar-feeding insects can be achieved by drip irrigation or furrow application, by treating the soil with for example pre- or post-planting soil drench, or by treating the seeds of a plant before planting.
Seed treatment can be applied to all types of seeds, including those from which plants genetically modified to express specialized traits will germinate. Representative examples include those expressing proteins toxic to invertebrate pests, such as Bacillus thuringiensis or other insecticidal toxins, those expressing herbicide resistance, such as “Roundup Ready” seed, or those with “stacked” foreign genes expressing insecticidal toxins, herbicide resistance, nutrition-enhancement, drought resistance, or any other beneficial traits. Furthermore, such seed treatments with the molecules of Formula One may further enhance the ability of a plant to better withstand stressful growing conditions. This results in a healthier, more vigorous plant, which can lead to higher yields at harvest time. Generally, about 1 gram of the molecules of Formula One to about 500 grams per 100,000 seeds is expected to provide good benefits, amounts from about 10 grams to about 100 grams per 100,000 seeds is expected to provide better benefits, and amounts from about 25 grams to about 75 grams per 100,000 seeds is expected to provide even better benefits.
It should be readily apparent that the molecules of Formula One may be used on, in, or around plants genetically modified to express specialized traits, such as Bacillus thuringiensis or other insecticidal toxins, or those expressing herbicide resistance, or those with “stacked” foreign genes expressing insecticidal toxins, herbicide resistance, nutrition-enhancement, or any other beneficial traits.
The molecules of Formula One may be used for controlling endoparasites and ectoparasites in the veterinary medicine sector or in the field of non-human animal keeping. The molecules of Formula One are applied, such as by oral administration in the form of, for example, tablets, capsules, drinks, granules, by dermal application in the form of, for example, dipping, spraying, pouring on, spotting on, and dusting, and by parenteral administration in the form of, for example, an injection.
The molecules of Formula One may also be employed advantageously in livestock keeping, for example, cattle, sheep, pigs, chickens, and geese. They may also be employed advantageously in pets such as, horses, dogs, and cats. Particular pests to control would be fleas and ticks that are bothersome to such animals. Suitable formulations are administered orally to the animals with the drinking water or feed. The dosages and formulations that are suitable depend on the species.
The molecules of Formula One may also be used for controlling parasitic worms, especially of the intestine, in the animals listed above.
The molecules of Formula One may also be employed in therapeutic methods for human health care. Such methods include, but are limited to, oral administration in the form of, for example, tablets, capsules, drinks, granules, and by dermal application.
Pests around the world have been migrating to new environments (for such pest) and thereafter becoming a new invasive species in such new environment. The molecules of Formula One may also be used on such new invasive species to control them in such new environment.
The molecules of Formula One may also be used in an area where plants, such as crops, are growing (e.g. pre-planting, planting, pre-harvesting) and where there are low levels (even no actual presence) of pests that can commercially damage such plants. The use of such molecules in such area is to benefit the plants being grown in the area. Such benefits, may include, but are not limited to, improving the health of a plant, improving the yield of a plant (e.g. increased biomass and/or increased content of valuable ingredients), improving the vigor of a plant (e.g. improved plant growth and/or greener leaves), improving the quality of a plant (e.g. improved content or composition of certain ingredients), and improving the tolerance to abiotic and/or biotic stress of the plant.
Before a pesticide can be used or sold commercially, such pesticide undergoes lengthy evaluation processes by various governmental authorities (local, regional, state, national, and international). Voluminous data requirements are specified by regulatory authorities and must be addressed through data generation and submission by the product registrant or by a third party on the product registrant's behalf, often using a computer with a connection to the World Wide Web. These governmental authorities then review such data and if a determination of safety is concluded, provide the potential user or seller with product registration approval. Thereafter, in that locality where the product registration is granted and supported, such user or seller may use or sell such pesticide.
A molecule according to Formula One can be tested to determine its efficacy against pests. Furthermore, mode of action studies can be conducted to determine if said molecule has a different mode of action than other pesticides. Thereafter, such acquired data can be disseminated, such as by the internet, to third parties.
