Details of the Invention

For descriptive purposes, Q-1, where R_a and R_b are H, is used as a representative value of Q in the discussion that follows and is referred to by the following numbering system:

Compounds of Formula I can be prepared by the reaction of aryl isocyanates of Formula II and substituted 3,3a,4,5-tetrahydro-2H-pyrazolo- [4,3-c]quinolines of Formula III as shown in Scheme I. Typical reactions involve the combination of equimolar amounts of II and III in aprotic organic solvents including ether, ethyl acetate,

tetrahydrofuran, or dichloromethane. The temperature at which the reaction is run can be between -20°C and 80°C, with preferred temperatures being in the range of about -10°C to 40°C.

Scheme 1

II III

Z=R₆ or R₁₆ Tetrahydropyrazoloquinolines of Formula III can be prepared by acid hydrolysis of their

phosphorylated derivatives of Formula IV, as shown in Scheme 2.

Scheme 2

1

IV: Z = R₆ or R₁₆

R₁₇= Me or Et

The reaction of Scheme 2 is generally carried out by contacting the substrate with one to three equivalents of a strong acid such as HCl or p-toluene sulfonic acid, optionally containing some water, in a solvent such as ethanol or dioxane for 1 to 72 hours at 50°C to 100°C. The initial product of the

reaction is a salt of III which can either be

neutralized and extracted into an organic solvent for use in the reaction of Scheme 1, or used in that reaction directly in the presence of one to two equivalents of a suitable organic or inorganic base.

An alternate method for preparing compounds of Formula IV which are not suited to the reaction conditions described above is to exchange one bridgehead N-substituent for another, as outlined in Scheme 3.

Scheme 3

C R

IV: Z=protecting group IV: Z= H

IV Z = R₆ or R_{1 6} In reaction (A) of Scheme 3, a compound of Formula IV wherein the Z substituent is a suitable protecting group, such as i-butyloxycarbonyl, benzyl, or trifluoroacetyl, can be deprotected by reaction conditions suited to the particular protecting group, such as acidic, hydrogenolytic, or basic conditions, respectively. Such protecting groups and methods for their removal are well-known to one skilled in the art.

In reaction (B) of Scheme 3, the deprotected compound of Formula IV is typically combined with one equivalent of an alkylating agent corresponding to the desired Z substituent in an inert solvent such as dimethylformamide or tetrahydrofuran in the presence of one equivalent of a strong base such as sodium hydride at a temperature of between 0°C and 80°C for 0.1 to 24 hours. The product can be isolated by concentration, dilution with water, extraction into an organic solvent such as ether, and concentration. The product can be purified by crystallization or chromatography on silica gel, or it may be carried along as such to the following reaction.

The compounds of Formula IV are produced by the cyclization reaction of an olefinic phosphoryl- hydrazone of Formula V induced by the combination of a mild base such as triethylamine and a mild

halogenating agent such as N-bromosuccinimide, as shown in Scheme 4. Scheme 4

Z=R₆ or R_{1 6}

R_{1 7}=Me or Et

In the reaction of Scheme 4, the hydrazone of Formula V is typically dissolved in an inert,

anhydrous solvent in the presence of one of the base/haloimide components at -20 to 50° and the other component is added gradually. The product can be isolated by washing the reaction mixture with water, evaporating the solvent, and either recrystallizing or chromatographing to remove by-products.

The synthesis of compounds of Formula V can be accomplished by condensing an aldehyde of Formula VI with diethyl or dimethyl phosphorohydrazidate VII, as shown in Scheme 5. Scheme 5

VI VII

Z=R₆ or R₁₆ R₁₇ = Me or Et

The reaction of Scheme 5 can be conducted by contacting aldehyde VI and compound VII in an inert solvent such as dichloromethane for 0.1 to 16 hours, optionally in the presence of a catalytic (0.1 to 10%) amount of an acid such as acetic or p-toluene sulfonic, and optionally in the presence of an inorganic drying agent such as anhydrous magnesium sulfate. The product can be isolated by washing out excess VII with water and concentrating the dried solution. It can be purified, if desired, by

recrystallization or chromatography.

Compounds of Formula VI can be prepared by reacting, for example, an N-sulfonyl or N-benzyl anthranilic aldehyde of Formula VIII with alkylating agents of Formula IX, wherein L is a suitable

leaving-group, such as Cl, Br, I, OSO₂CH₃, or OSO₂Ar, as shown in Scheme 6. Scheme 6

VIII IX

Z = R₆ or R_{1 6} L = halo, OSO₂Me, etc.

The reaction of Scheme 6 is typically carried out by combining equimolar quantities of VIII and IX in a suitable solvent for alkylation reactions, such as dimethylformamide (DMF) in the presence of

slightly more than one equivalent of a suitable base, such as anhydrous potassium carbonate, and stirring vigorously at a temperature between 0° and 100°C.

The product is generally isolated by diluting the mixture with water and filtering the precipitated product or extracting into a solvent such as ether. Recrystallization or chromatography affords the pure product. Compounds of Formula VIII are recognized by those skilled in the art as being obtainable from substituted anilines or heterocyclic amines by known methods. Compounds of Formula IX are either known or are readily available from olefins or allylic

alcohols by known methods. In those cases where an R₆ or R₁₆ substituent would not be compatible with the reaction conditions prescribed in Schemes 2, 3, 4, 5, or 6, a strategy outlined in Scheme 7 can be employed.

Scheme 7

I I

( PG = protecting group) ( R_{1 6} is H)

( B) I ( R_{1 6} is H) I ( neit her R₆ nor

R_{1 6} is H)

In reaction A of Scheme 7, a compound of Formula I wherein the R₆ or R₁₆ substituent is replaced by a suitable protecting group, such as benzyloxycarbonyl, benzyl, trichloroethoxycarbonyl, trichloroacetyl, and the like, can be deprotected by conditions suited to that protecting group. Such protecting groups and methods for their removal are well known to one skilled in the art.

In reaction B of Scheme 7, the deprotected compound of Formula I is typically combined with an electrophilic species (E) corresponding to the desired R₆ or R₁₆ substituent (acyl halide or anhydride, alkyl chloroformate, carbamoyl halide, chlorophosphate, etc.) optionally in the presence of an acid-binding agent in an inert solvent such as dichloromethane, and the product of Formula I is isolated by washing with water, concentration, and crystallization or chromatography.

Using the methods described for Q=Q-1, the compounds of Formula I for which Q=Q-2 to Q-11 can also be prepared. Methods for preparing

intermediates for Q-9 and Q-10 can be found in the following references: J. Am. Chem. Soc., 100, 7600 (1978), J. Org. Chem., 50, 2066 (1985), and

Formulation and Use

The compounds of this invention will generally be used in formulation with an agriculturally

suitable carrier comprising a liquid or solid diluent or an organic solvent. Useful formulations of the compounds of Formula I can be prepared in

conventional ways. They include dusts, granules, baits, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry

flowables and the like. Many of these can be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from

about one to several hundred liters per hectare.

High strength compositions are primarily used as

intermediates for further formulation. The

formulations, broadly, contain from less than about 1% to 99% by weight of active ingredient(s) and at least one of a) about 0.1% to 20% surfactant(s) and b) about 5% to 99% solid or liquid diluent(s). More specifically, they will contain effective amounts of these ingredients in the following approximate

proportions:

Percent by weight

Active

Ingredient Diluent(s) Surfactant(s)

Wettable Powders 25-90 0-74 1-10

Oil Suspensions, 5-50 40-95 0-15

Emulsions, Solutions,

(including Emulsifiable

Concentrates)

Dusts 1-25 70-99 0-5

Granules, Baits 0.01-95 5-99 0-15

and Pellets

High Strength 90-99 0-10 0-2

Compositions Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, New

Jersey. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0°C.

"McCutcheon's Detergents and Emulsifiers Annual", Allured Publ. Corp., Ridgewόod, New Jersey, as well as Sisely and Wood, "Encyclopedia of Surface Active

Agents", Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, U.S. 3,060,084). Granules and pellets can be made by spraying the active

material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning,

"Agglomeration", Chemical Engineering. December 4, 1967, pages 147 and following, and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York, 1963, pages 8 to 59 and following.

(tephritidae), and soil maggots; adults and immatures of the order

Thysanoptera including onion thrips and other foliar feeding thrips.

The compounds are also active against

economically important livestock, household, public and animal health pests such as: arthropod pests of the order Hymenoptera including carpenter ants, bees, hornets, and wasps; arthropod pests of the order Diptera including house flies, stable flies, face flies, horn flies, blow flies, and other muscoid fly pests, horse flies, deer flies and other Brachycera, mosquitoes, black flies, biting midges, sand flies, sciarids, and other Nematocera: arthropod pests of the order Orthoptera including cockroaches and crickets; arthropod pests of the order Isoptera

including the Eastern subterranean termite and other termites; arthropod pests of the order Mallophaga and

Anoplura including the head louse, body louse, chicken head louse and other sucking and chewing parasitic lice that attack man and animals; arthropod pests of the order Siphonoptera including the cat flea, dog flea and other fleas.

The specific species for which control is exemplified are: fall armyworm, Spodoptera

fruigiperda: tobacco budworm, Heliothis virescens: boll weevil, Anthonomus grandis; aster leafhopper, Macrosteles fascifrons: black bean aphid, (Aphis Fabae); southern corn rootworm, Diabrotica

undecimpunctata. The pest control protection afforded by the compounds of the present invention is not limited, however, to these species. The compounds of this invention may also be utilized as rodenticides.

Application

Arthropod pests are controlled and protection of agronomic crops, animal and human health is achieved by applying one or more of the Formula I compounds of this invention, in an effective amount, to the

environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Because of the diversity of habitat and behavior of these arthropod pest species, many

different methods of application are employed. A preferred method of application is by spraying with equipment that distributes the compound in the

environment of the pests, on the foliage, animal, person, or premise, in the soil or animal, to the plant part that is infested or needs to be protected. Alternatively, granular formulations of these toxicant compounds can be applied to or incorporated into the soil. Other methods of application can also be employed including direct and residual sprays, aerial sprays, baits, eartags, boluses, foggers, aerosols, and many others. The compounds can be incorporated into baits that are consumed by the arthropods or in devices such as traps and the like which entice them to ingest or otherwise contact the compounds.

The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of

application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, and

synergists such as piperonyl butoxide often enhance the efficacy of the compounds of Formula I.

The rate of application of the Formula I

compounds required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, etc. In general, application rates of 0.01 to 2 kg of active ingredient per hectare are sufficient to provide large-scale effective control of pests in agronomic ecosystems under normal

circumstances, but as little as 0.001 kg/hectare or as much as 8 kg hectare may be required. For

nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as about 0.1 mg/square meter or as much as 150 mg/square meter may be required.

The following tests demonstrate the control efficacy of compounds of Formula I on specific pests; see Index Table A for compound descriptions.

TEST A

Fall Armyworm

Test units, each consisting of an 8-ounce plastic cup containing a layer of wheat germ diet, approximately 0.5 cm thick, were prepared. Ten third-instar larvae of fall armyworm (Spodoptera frugiperda) were placed into each cup. Solutions of each of the test compounds (acetone/distilled water 75/25 solvent) were sprayed onto the cups, a single solution per set of three cups. Spraying was

accomplished by passing the cups, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 p.s.i. The cups were then covered and held at 27°C and 50% relative humidity for 72 hours, after which time readings were taken. Of the compounds tested, the following resulted in greater than or equal to 80% mortality: 1, 3, 4, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16 and 17.

TEST B

Tobacco Budworm

The test procedure of Test A was repeated for efficacy against third-instar larvae of the tobacco budworm (Heliothis virescens) except that mortality was assessed at 48 hours. Of the compounds tested, the following resulted in greater than or equal to 80% mortality: 1, 3, 4, 6, 7, 8, 10, 11, 12, 13, 14, 15 and 17. TEST C

Southern Corn Rootworm

Test units, each consisting of an 8-ounce plastic cup containing 1 sprouted corn seed, were prepared. Sets of three test units were sprayed as described in Test A with individual solutions of the test compounds. After the spray on the cups had dried, five third-instar larvae of the southern corn rootworm (Diabrotica undecimounctata howardi) were placed into each cup. A moistened dental wick was inserted into each cup to prevent drying and the cups were then covered. The cups were then held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested, the following resulted in greater than or equal to 80% mortality: 1, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 17.

TEST D

Boll Weevil

Five adult boll weevils (Anthonomus grandis) were placed into each of a series of 9-ounce cups. The test procedure employed was then otherwise the same as in Test A. Mortality readings were taken 48 hours after treatment. Of the compounds tested, the following resulted in greater than or equal to 80% mortality: 1, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 and 17.

TEST E

Aster Leafhopper

Test units were prepared from a series of 12-ounce cups, each containing oat (Avena sativa) seedlings in a 1-inch layer of sterilized soil. The test units were sprayed as described in Test A with individual solutions of the below-listed compounds. After the oats had dried from the spraying, between 10 and 15 adult aster leafhoppers (Mascrosteles

fascifrons) were aspirated into each of the covered cups. The cups were held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested on aster leafhopper, the following resulted in greater than or equal to 80% mortality: 1, 6, 7, 9, 12, 13, 15 and 17.

TEST F

Two-Spotted Spider Mite

Test units, each consisting of one-inch square sections of kidney bean leaves, were infested with 20 to 30 adult two-spotted spider mites (Tetranychus urticae) and sprayed as described in Test A with individual solutions of the below-listed compounds.

Three test units were sprayed per solution. Sprayed leaf sections were then placed on a layer of moistened cotton in a Petri dish «and held at 27°C and 50%

relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested, none resulted in greater than or equal to 80% mortality.
