Substituted cyclopropyl phenoxymethyl phenyl carbamates and their use as fungicides

The present invention relates to benzyloxy substituted phenyl compounds, compositions containing these compounds and methods for controlling fungi by the use of a fungitoxic amount of these compounds.
It is known that carbamates of certain benzyloxy substituted phenyl compounds are useful as fungicides. The substitution of the phenyl ring is known in the art (see for example WO9315046). These compounds have met with mixed success in their use as fungicides. As a result, there is a constant need for new and effective fungicides. The problem of the provision of further fungicidal compounds is addressed by the present invention.
We have discovered phenyl derivatives which possess a substituted cyclopropyl moiety. These novel derivatives possess fungicidal properties.
The novel benzyloxy substituted phenyl compounds of the present invention have the Formula (I): ##STR2## wherein m and n are the integers 0 and 1, provided that m+n is 0 or 1;

As used in Table I to IV Ph is understood to be phenyl.
The compounds of Formula I can be prepared by a variety of synthetic routes. A general overview of synthesis methods for cyclopropanes is described in March, Advanced Organic Chemistry, 4th Ed. pp. 866-873 and references therein.
When n and m are both zero, R.sub.1 and R.sub.4 are hydrogen, and at least one of R.sub.2 and R.sub.3 is hydrogen, the compounds of formula (I) are prepared in a four step sequence shown in Scheme A. ##STR16##
The substituted cyclopropyl phenols XVI are prepared from the pyrazolines XV which are prepared from .alpha.,.beta. unsaturated compounds (XIV). These enones can be prepared by conventional condensation techniques. For example Organic Reactions, Volume 16 describes the general aldol condensation and specifically the condensation of benzaldehydes with ketones. A hydroxybenzaldehyde is condensed with a ketone, RCOCH.sub.2 R.sub.2, which when R.sub.2 .dbd.H is a methyl ketone, provides the unsaturated intermediate XIV'. Substituted hydroxybenzaldehyde such as ortho, meta, or parahydroxybenzaldehyde provides three corresponding regioisomeric intermediates XIV and XIV'. A variety of reaction condition can be employed to prepare the enones XIV and XIV' which are described in Organic Reactions Vol 16 pp. 69-85. For example a ketone is dissolved in hydroxylic solvent (i.e. an hydroxidecontaining hydrophilic solvent) such as methanol, ethanol, etc., to which is added dropwise a solution of the hydroxybenzaldehyde in an aqueous basic solution. The bases used can be alkali metal hydroxides, such as potassium or sodium hydroxide and the dropwise addition is conducted from 0.degree. C. to 35.degree. C. preferably at ambient temperature.
The intermediate enones XIV and XIV' are reacted with hydrazine to provide the intermediate XV and XV' pyrazoline. Typical preparation of pyrazoline from unsaturated enones by treatment with hydrazine are described in Synthetic Commun, 25(12), 1877-1883 (1995); JACS 73, 3840 (1951); Indian J. Chem Soc Sect B 98-104 (1992) and J. Indian Chem Soc 643-644 (1993). For example, in JACS 73, 3840 (1951) styryl cyclopropyl ketone is reacted with aqueous hydrazine in 95% ethanol and stirred on a steam bath for 1 hr. which after distillation gave the pyrazoline in 86% yield. Similarly in Synthetic Commun, 25(12), 1877-1883 (1995) chalcones were treated with hydrazine monohydrate and stirred at reflux in ethanol and gave the pyrazolines in >90% yield. The intermediate pyrazoline XV' is heated with caustic (NaOH) at 250.degree. C. as described in Synthetic Commun, 25(12) and JACS 73, 3840 (1951) to provide the cyclopropyl phenols XVI'.

Scheme C describes the preparation of compounds of the formula (I) where R.sub.1 and R.sub.4 are hydrogen and at least one of R.sub.2 and R.sub.3 is hydrogen. The .alpha.,.beta. unsaturated compounds (XVII) can be prepared by conventional condensation techniques. For example Organic Reactions, Volume 16 describes the general aldol condensation and specifically the condensation of aldehydes with ketones. An aldehyde, for example a substituted benzaldehyde is condensed with an hydroxyphenylketone, (OH)PHCOCH.sub.2 R.sub.2, which, when R.sub.2 .dbd.H is a methyl ketone, provides the unsaturated intermediate XVII'. ##STR18##
Substituted hydroxyphenylketones provide the three regioisomeric intermediates XVII (R.sub.2 is not H) and substituted hydroxyphenylketone such as ortho, meta, or parahydroxyacetophenone provide three regioisomeric intermediates XVII' where R.sub.2 .dbd.H. The intermediate enones XVII and XVII' are reacted with hydrazine in the same manner as intermediate XIV and XIV' (Scheme A) resulting in the cyclopropyl phenols XVI and XVI'; as described in Scheme C. The cyclopropylphenols XVI' are used to prepare compounds of Table 1 of formula II, III, and IV as described in Scheme A.

The chemistry of sulfur ylides is described in Trost and Melvin, Sulfur Ylids, Academic Press, Ne York, N.Y. 1975 and in Block, Reactions of Organosulfur Compounds, pp. 91-123, Academic Press, New York, N.Y. 1978. Typical reaction conditions for sulfur ylide formation from a dimethylsulfoxonium salt utilizes bases such as hydroxides, metal hydrides and alkoxides in solvents such as dimethoxyethane, dimethylsufoxide and water depending on the base employed. The reactions are conducted from 0 to 20.degree. C. preferably from 10-15.degree. C. and preferably with alkali metal hydroxides in dimethylsulfoxide. ##STR19##

For a general review of the Wittig olefination see Cadogan Organophosphorus Reagents in Organic Synthesis, 1979 and Johnson Ylid Chemistry, 1966. Typical reactio conditions for the Wittig reaction from a phosphonium salt utilize bases such as, metal hydrides and alkoxides in solvents such as toluene, THF, ether, dimethoxyethane and ethanol depending on the base employed. The reactions are conducted from 20 to 120.degree. C. preferably from 75 to 120.degree. C. and preferably with alkoxides such as potassium tertbutoxide in THF.

The compounds were dissolved in a 2:1:1 mixture of water, acetone and methanol (by volume), sprayed onto the plants, allowed to dry (two hours) and then the plants were inoculated with fungal spores. Each test utilized control plants which were sprayed with the water, acetone and methanol mixture and inoculated. The remainder of the technique of each of the tests is given below along with the results for various compounds described herein by the Compound # against the various fungi at a dose of 300 gams per hectare. The results are reported as percent disease control, compared to the control wherein one hundred was rated as total disease control and zero as no disease control. The application of the fungi to the test plants was as follows:
Wheat Leaf Rust (WLR)
Puccinia recondita (f. sp. tritici) was cultured on 7 day old wheat (cultivar Fielder) over a 12 day period in the greenhouse. Spores were collected from the leaves by settling on aluminum foil. The spores were cleaned by sieving through a 250 micron opening screen and stored or used fresh. Storage employed sealed bags in an Ultralow freezer. A spore suspension was prepared from dry uredia by adding 20 mg (9.5 million spores) per mL of Soltrol oil. The suspension was dispensed into gelatin capsules (0.7 mL capacity) which attach to the oil atomizers. One capsule is used per flat of twenty 2 inch square pots of 7 day old Fielder wheat. After waiting for at least 15 minutes for the oil to evaporate from the wheat leaves, the plants were placed in a dark mist chamber (18-20.degree. C. and 100% relative humidity) for 24 hours. The plants were then put in the greenhouse for the latent period and scored after 12 days for disease levels. For protective tests the plants are inoculated one day after spraying the plants with the fungicide compounds.
Wheat Leaf Blotch (SNW)
Cultures of Septoria nodorum was maintained on Czapek-Dox V-8 juice agar plates in an incubator 20.degree. C. with alternating periods of 12 hours of light and 12 hours of darkenss for 3 weeks. A water suspension of the spores was obtained by shaking the portion of the plate with fungal material in deionized water and filtering through cheesecloth. The spore-containing water suspension was diluted to a spore concentration of 3.0.times.10.sup.6 spores per ml. The inoculum was dispersed by a DeVilbiss atomizer over one week oil Fielder wheat plants which had been previously sprayed with the fungicide compound. The inoculated plants were placed in a humidity cabinet at 20.degree. C. with alternating 12 hours of light and 12 hours of darkness for 7 days. The inoculated seedlings were then moved to a controlled environment room at 20.degree. C. for 2 days of incubation. Disease control values were recorded as percent control.
Wheat Powdery Mildew (WPM)
Erysiphe graminis (f. sp. tritici) was cultured on wheat seedlings in a controlled temperature room at 18.degree. C. Mildew spores were shaken from the culture plants onto 7 day old wheat seedlings which had been previously sprayed with the fungicide compound. The inoculated seedlings were kept in a controlled temperature room at 18.degree. C. and subirrigated. The percent disease control was rated 7 days after the inoculation.

Sphaerotheca fulginea was maintained on cucumber plants, cv. Bush Champion, in the greenhouse. Inoculum was prepared by washing the spores from the leaves with water which had 1 drop of Tween 80 per 100 ml. After shaking the plants, the inoculum was filtered through cheese cloth and misted onto the plants with a squirt bottle mister. The spore count was 100,000 spores/ml. The plants were then placed in the greenhouse for infection and incubation. The plants were scored seven days after inoculation. Disease control values were recorded as percent control.
Tomator Late Blight (TLB)
Cultures of Phytophthora infestans were maintained on green pea-amended agar for two to three to four weeks. The spores were washed from the agar with water and dipsersed by DeVilbiss atomizer over the leaves of 3-week old Pixie tomato plants which had been sprayed previously with experimental fungicides. The inoculated plants were placed in a humidity cabinet at 20.degree. C. for 24 hours for infection. The plants were then removed to a controlled environment room at 20.degree. C. The plants were scored for disease control after five days.
Grape Downy Mildew (GDM)
Plasmopara viticola was maintained on leaves of live grape plants, cv. Delaware, in a controlled temperature chamber at 20.degree. C. in humid air with moderate light intensity for 7 to 8 days. A water suspension of the spores from infested leaves was obtained and the spore concentration was adjusted to about 3.times.10.sup.5 per ml of water. Delaware grape plants were inoculated by spraying the underside of leaves with a De Vilbiss atomizer until small drops were observed on the leaves. The inoculated plants were incubated in a mist chamber for 24 hours at 20.degree. C. The plants were then removed to a controlled environmental room at 20.degree. C. Disease control values were recorded as percent control seven days after inoculation.

The compounds of this invention are useful as agricultural fungicides and, as such, can be applied to various loci such as the seed, the soil or the foliage of plants to be protected.
The compounds of this invention can be applied as fungicidal sprays by methods commonly employed, such as conventional high-volume hydraulic sprays, low-volume sprays, air-blast spray, aerial sprays and dusts. The dilution and rate of application will depend upon the type of equipment employed, the method of application, plants to be treated and diseases to be controlled. Generally, the compounds of this invention will be applied in amount of from about 0.005 kilogram to about 50 kilograms per hectare and preferably from about 0.025 to about 25 kilograms per hectare of the active ingredient.
As a seed protectant, the amount of toxicant coated on the seed is usually at a dosage rate of from about 0.05 to about 20, preferably from about 0.05 to about 4, and more preferably from about 0.1 to about 1 grams per humdred 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 from about 0.02 to about 20, preferably from about 0.05 to about 10, and more preferaby from about 0.1 to about 5 kilograms per hectare. As a foliar fungicide, the toxicant is usually applied to growing plants at a rate of from about 0.01 to about 10, preferably from about 0.02 to 5, and more preferably from about 0.25 to about 1 kilograms per hectare.
Inasmuch as the compounds of this invention display fungicidal activity, these compounds can be combined with other known fungicides to provide broad spectrum activity. Suitable fungicides include, but are not limited to, those compounds listed in U.S. Pat. No. 5,252,594 (see in particular columns 14 and 15).
The compounds of this invention can be advantageously employed in various ways. Since these compounds possess broad spectrum fungicidal activity, they can be employed in the storage of cereal grain. These compounds can also be employed as fungicides in cereals including wheat, barley and rye, in rice, peanuts, beans and grapes, on turf, in fruit, nut and vegetable orchards, and for golf course applications.
Examples of diseases against which the compounds of the invention are useful include helminthosporium of corn and barley, wheat and barley powdery mildew, wheat leaf and stem rusts, tomator early blight, tomato late blight, peanut early leaf spot, grape powdery mildew, grape black rot, apple scab, apple powdery mildew, cucumber powdery mildew, brown rot of fruits, botrytis, bean powdery mildew, cucumber anthracnose, wheat septoria nodorum, rice sheath blight and rice blast.
The compounds of th present invention can be used in the form of compositions or formulations. Examples of the preparation of compositions and formulations can be found in the American Chemical Society publication "Pesticidal Formulation Research," (1969), Advances in Chemistry Series No. 86, written by Wade Van Valkenburg; and the Marcel Kekker, Inc. publication "Pesticide Formulations", (1973) edited by Wade Van Valkenburg. In these compositions and formulations, the active substance is mixed with conventional inert agronomically acceptable (i.e., plant compatible and/or pesticidally inert) pesticide diluents or extenders such as solid carrier material or liquid carrier material, of the type usable in conventional pesticide compositions or formulations. By "agronomically acceptable carrier" is meant any substance which can be used to dissolve, disperse of diffuse the active ingredient in the composition without impairing the active ingredient's effectiveness and which by itself has no significant detrimental effect on the soil, equipment, desirable plants, or agronomic enviornment. If desired, adjuvants such as surfactants, stabilizers, antifoam agents and anti-drift agents may also be combined.
Examples of compositions and formulations according to the invention are aqueous solution and dispersions, oily solutions and oil dispersions, pastes, dusting powders, wettable powders, emulsifiable concentrates, flowables, granules, baits, invert emulsions, aerosol compositions and fumigating candles. Wettable powders, pastes, flowables and emulsifiable concentrates are concentrated preparations which are diluted with water before or during use. In such formulations, the compounds are extended with a liquid or solid carrier and, when desired, suitable surfactants are incorporated. Baits are preparations generally comprising a food or other substance attractive to insects, that includes at least one compound of the instant invention.
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. A listing of such adjuvants commonly used in the art, and a discussion of adjuvants, can be found in many references, such as in the John W. McCutcheon, Inc. publication "Detergents and Emulsifiers, Annual."
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 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 prepration 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%.
Wettable powders suitable for spraying, can be prepared by admixing the compound with a finely divided solid, such as clay, inorganic silicate and carbonate, and silica 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 from about 20% to about 99%, preferably from about 40% to about 75%. A typical wettable powder is made by blending 50 parts of a compound of Formula I, 45 parts of a synthetic precipitated hydrated silicon dioxide, such as that sold under the trademark Hi-SilR, and 5 parts of sodium lignosulfonate. In another preparation of 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.RTM.3.
Dusts are prepared by mixing compounds of Formula I, or the enantiomorphs, salts and complexes thereof with finely divided inert solids which can be organic or inorganic in nature. Materials useful for this purpose include botanical flours, silicas, silicates, carbonates and clays. One convenient method of preparing a dust is to dilute a wettable powder with a finely divided carrier. Dust concentrates containing from about 20% to about 80% of the active ingredient are commonly made and are subsequently diluted to from about 1% to about 10% use concentration.
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 comprises 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 habit at 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.
