Phenoxyalkylaminopyrimidine derivatives and insecticidal and acaricidal compositions containing them

Description

BACKGROUND OF THE INVENTION
The present invention relates to a series of new phenoxyalkylaminopyrimidine derivtives which have valuable insecticidal and acaricidal activities and also provides processes for preparing these derivatives and compositions containing them as the active ingredient.
Insects and acarids cause considerable damage to plants and can represent a serious danger to health; at best, they are a major nuisance. Accordingly, large sums are spent to destroy or deter them. Although many insecticides and acaricides are available, a large number of these have to be used with care, because they can endanger animals or because of their phytotocicity. Moreover, because insects and acarids have short life cycles, they can develop immunity to many of the commonly used insecticides and acaricides, and, accordingly, there is always a continuing need for new compounds exhibiting insecticidal and acaricidal properties.
A number of phenoxyalkylamine derivatives is known, e.g. from U.S. Pat. Nos. 4,213,987, 4,435,402 and 4,562,193. These known compounds can, broadly speaking, be represented by the formula: ##STR2## in which: R.sup.a and R.sup.b each represent alkyl groups;
R.sup.c represents an alkylene group; and
Het represents a heterocyclic ring system, for example a pyrimidine ring or a pyrimidine ring fused to another ring, e.g. fused to a benzene ring (to form a quinazoline ring) or fused to a cycloalkane or thiophene ring, and, of course, such rings are optionally substituted.
Such compounds have insecticidal and acaricidal activities and are effective for the eradication of various noxious insects and mites which are problems in agriculture or horticulture, for example the diamondback moth (Plutellae xylostella), aphids, the two-spotted spider mite (Tetranychus urticae) and the citrus red mite (Panonychus citri).
We have now found that a class of compounds similar to the known ones described above, but which have a highly specific class of substituted alkyl groups at the 4-position of the phenyl group in the formula shown above, have insecticidal and acaricidal activities far superior to those of the known compounds, and, in particular, they have superb acaricidal activity.

Preferably, R.sup.1 represents a hydrogen atom or a methyl group.
Where R.sup.2 or R.sup.3 represents a C.sub.2 -C.sub.4 alkoxyalkyl or alkylthioalkyl group, the alkoxy and alkyl parts may be straight or branched chain groups, but are preferably straight chain groups and examples include the methoxymethyl, ethoxymethyl, propoxymethyl, 2-methoxyethyl, 2-ethoxyethyl, 3-methoxypropyl, methylthiomethyl, ethylthiomethyl, propylthiomethyl, 2-methylthioethyl, 2-ethylthioethyl and 3-methylthiopropyl groups.

Where R.sup.2 and R.sup.3, together with the carbon atoms to which they are attached, form an additional 5- or 6-membered ring, this may be a carbocyclic ring or it may be a heterocyclic ring containing a single oxygen or sulfur atom, the carbocyclic or heterocyclic ring being fused to the pyrimidine ring via the 5- and 6-carbon atoms of the pyrimidine ring. Apart from the carbon atoms through which the fusion occurs, the remaining atoms of the ring formed by R.sup.2 and R.sup.3 may be saturated or unsaturated and the resulting ring may be fully unsaturated or only partially unsaturated. Examples of preferred rings which may be formed by R.sup.2, R.sup.3 and the fusion carbon atoms of the pyrimidine ring include cyclopentene rings, cyclohexene rings, cyclohexadiene rings, benzene rings, thiophene rings and furan rings. In particular, we prefer that the part of the compound of formula (I) represented by the partial formula (I'): ##STR4## should be represented by any one of the partial formulae (Ia)-(Ih): ##STR5## (in which R.sup.1 is as defined above).

The compounds of the present invention contain a basic nitrogen atom and, accordingly, can readily form acid addition salts. There is no particular restriction on the nature of such salts, provided that, where the compounds are intended for agricultural or horticultural use, the resulting salts should not have a reduced activity (or unacceptably reduced activity) or increased phytotoxicity (or unacceptably increased phytotoxicity) as compared with the free base. However, where the salts are to be used for other purposes, e.g. as intermediates, even this restriction does not apply. Examples of acids which may be used to form salts include: inorganic acids, such as hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid, phosphoric acid or perchloric acid; organic carboxylic acids, such as formic acid, oxalic acid, trihaloacetic acids, fumaric acid, adipic acid, phthalic acid, malonic acid, succinic acid, glutaric acid, maleic acid and citric acid; and organic sulfonic acids, such as methanesulfonic acid, benzenesulfonic acid and p-toluenesulfonic acid.
Depending upon the various substituents, the compounds of formula (I) may exist in the form of various optical isomers and, although these isomers are indicated herein by a single formula, the present invention envisages both the individual isolated isomers and mixtures thereof. Where individual isomers are desired, these may be prepared by stereospecific synthesis techniques or a mixture of isomers may be prepared and the individual isomers separated by conventional resolution methods. As is well-known in the art, the biological activities of such isomers may differ, and it is a matter of routine experimentation to determine which of the isomers has the better activity.

Of the compounds listed above, preferred compounds are Compounds No. 12, 75 and 99 and their acid addition salts.
Compounds of the invention can be prepared by the methods illustrated below.
METHOD A
The compounds of the invention may be prepared by condensation between a pyrimidine derivative of formula (II) and a phenoxyalkylamine of formula (III), as illustrated in the following reaction scheme: ##STR10##
In the above formulae, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and m are as defined above. G represents a radical to be eliminated. Amine condensation reactions of this type are well-known and the radical G may be any radical known for use in this type of reaction, without any particular limitation. Non-limiting examples of radicals which may be employed include: halogen atoms, such as chlorine, bromine or iodine atoms; C.sub.1 -C.sub.4 alkylthio groups, such as the methylthio, ethylthio, propylthio or butylthio groups; C.sub.1 -C.sub.4 alkanesulfonyloxy groups, in which the alkyl part is unsubstituted or has one or more halogen substituents, such as the methanesulfonyloxy, ethanesulfonyloxy or trifluoromethanesulfonyloxy groups; arenesulfonyloxy groups, such as the benzenesulfonyloxy or p-toluenesulfonyloxy groups; and the hydroxy group.
As can be seen clearly from the above reaction scheme, a compound of formula H-G is eliminated in the course of this reaction and it is, therefore, preferred to carry out the reaction in the presence of a scavenging compound which removes the compound H-G from the reaction mixture and thus facilitates the reaction; where the compound H-G is an acid, the scavenging compound is preferably an acid-binding agent and thus most preferably a base.
There is no particular restriction on the nature of the base to be employed, and examples of suitable bases include: organic bases, such as triethylamine, pyridine or N,N-diethylaniline; alkali metal hydroxides, such as sodium hydroxide or potassium hydroxide; and alkali metal carbonates, such as sodium carbonate or potassium carbonate.
The reaction is usually conducted in the presence of a solvent; however, it will also take place if the compounds of formulae (II) and (III) are heated to fusion in the absence of a solvent. Where a solvent is employed, its nature is not critical, provided that it has no adverse effect upon the reaction. Examples of suitable solvents include: aromatic, aliphatic and cycloaliphatic hydrocarbons and halogenated (e.g. chlorinated) derivatives thereof, such as benzene, toluene, xylene, methylnaphthalene, petroleum, ether, ligroin, hexane, chlorobenzene, dichlorobenzene, methylene chloride, chloroform, 1,2-dichloroethane, trichloroethylene or cyclohexane; ethers, such as diethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran or dioxane; ketones, such as acetone or methyl ethyl ketone; alcohols, such as methanol, ethanol or ethylene glycol, and mixtures of such alcohols with water; and mixtures of any two or more of the above solvents.
The reaction will take place over a wide range of temperatures and the precise reaction temperature chosen is not particularly critical. Usually, we prefer to carry out the reaction at a temperature which is not below room temperature and not greater than the boiling point of the solvent (if a solvent is employed) or not greater than the fusion temperature of the two reagents (if no solvent is employed). Preferably, in order to reduce the reaction time, the reaction is carried out with heating.
METHOD B
Compounds of the invention in which R.sup.6 represents a group of formula --A--B--(DO).sub.n --E, that is to say compounds of formula (VI), may be prepared by the reaction illustrated in the following reaction scheme: ##STR11##
In the above formulae, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, G, m, A, B, D and n are as defined above. X represents a halogen atom.
Step B1
In this step, a compound of formula (II) is condensed with a substituted phenoxyalkylamine of formula (IV). The reaction involved is essentially the same as that involved in Method A, described above, and may be carried out under the same conditions and employing the same solvents as described in relation to Method A.
Step B2
In this step, the compound of formula (V), prepared in step B1, is first reacted with a base and then reacted with a halogen compound of formula E--(OD).sub.n --X, to give the desired compound of formula (VI).
The nature of the base employed in the first part of this step is not critical, although we generally prefer to employ an inorganic base. Examples include: alkali metals, such as potassium or sodium; alkali metal hydrides, such as sodium hydride or potassium hydride; alkali metal amides, such as sodium amide; and alkali metal carbonates, such as sodium carbonate or potassium carbonate.
In the second part of this step, the resulting compound is reacted with the compound of formula E--(OD).sub.n --X. X represents a halogen atom and is preferably a chlorine or bromine atom.
Both parts of this step are preferably carried out in the presence of a solvent, the nature of which is not critical, provided that it has no adverse effect upon the reaction. Examples of suitable solvents include: ethers, such as diethyl ether, ethylene glycol dimethyl ether or dioxane; ketones, such as acetone or methyl ethyl ketone; and dimethylformamide.
The reaction will take place over a wide range of temperatures and the precise temperature chosen is not critical. However, in order to speed the reaction, we generally prefer that it should be carried out at a temperature greater than room temperature, and up to the boiling point of the solvent. Generally, the reaction is carried out with heating.
METHOD C
Compounds of the invention in which B represents a sulfur atom or an imino group, that is to say compounds of formula (XII), may be prepared as illustrated in the following reaction scheme: ##STR12##
In the above formulae, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, m, A, X, E, D and n are as defined above. [X] represents a halogenating agent. B.sup.a represents a sulfur atom or an imino group. The starting material for this reaction scheme, the compound of formula (VIII), may be prepared following essentially the same procedure as described in Method A.
Step C1
In this step, the compound of formula (VIII) is reacted with a halogenating agent [X]. The nature of the halogenating agent employed is not critical and any halogenating agent commonly used in organic reactions may equally be used here, provided that it has no adverse effect upon the remainder of the molecule. Suitable halogenating agents include, for example: thionyl halides, such as thionyl chloride or thionyl bromide; phosphorus oxyhalides, such as phosphorus oxychloride or phosphorus oxybromide; phosphorus pentahalides, such as phosphorus pentachloride; and phosphorus trihalides, such as phosphorus trichloride or phosphorus tribromide.
The reaction is preferably effected in the presence of a solvent, the nature of which is not critical, provided that it has no adverse effect upon the reaction. Suitable solvents include, for example: aromatic, aliphatic and cycloaliphatic hydrocarbons, which may be halogenated, such as benzene, toluene, xylene, methylnaphthalene, petroleum ether, ligroin, hexane, chlorobenzene, methylene chloride, chloroform, trichloroethylene or cyclohexane; and ethers, such as diethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran or dioxane. The reaction is preferably effected in the presence of a base, which likewise is not critical, although we generally prefer an organic base, such as triethylamine, pyridine or N,N-diethylaniline.
The reaction will take place over a wide range of temperatures and the precise temperature chosen is not critical. However, we generally prefer to carry out the reaction at a temperature between room temperature and the boiling point of the solvent employed, preferably with heating.
Step C2
In this step, the compound of formula (IX), prepared as in step C1, is reacted with an amine (X) or a mercaptan (XI), to give the desired compound of formula (XII).
The reaction is preferably effected in the presence of a solvent, the nature of which is not critical, provided that it has no adverse effect upon the reaction. Suitable solvents include, for example: aromatic, aliphatic and cycloaliphatic hydrocarbons, which may be halogenated, such as benzene, toluene, xylene, methylnaphthalene, petroleum ether, ligroin, hexane, chlorobenzene, methylene chloride, chloroform, trichloroethylene or cyclohexane; ethers, such as diethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran or dioxane; and alcohols, such as methanol, ethanol or ethylene glycol.
The reaction will take place over a wide range of temperatures, and we generally prefer to carry out the reaction at a temperature within the range from room temperature to 150.degree. C., more preferably with heating. Particularly where the amine (X) is employed, the reaction is preferably effected under superatmospheric pressure, in order to allow a higher temperature to be used.
METHOD D
Compounds of the invention in which R.sup.2 and R.sup.3 together form an optionally substituted furan or thiophene ring, e.g. compounds of formula (XV), can be prepared as illustrated in the following reaction scheme: ##STR13##
In the above formulae, R.sup.1, R.sup.4, R.sup.5, R.sup.6 and m are as defined above. Y represents an oxygen or sulfur atom. R.sup.11 and R.sup.12 are optional substituents on the furan or thiophene ring, that is to say they may be the same or different and each represents a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group or a halogen atom. R.sup.10 represents a C.sub.1 -C.sub.4 alkyl group, e.g. as defined above in relation to R.sup.1.
Step D1
In this step, the 3-cyano-2-(alkoxymethylene)iminothiophene (or furan) of formula (XIII) is reacted with a substituted phenoxyalkylamine of formula (III), as described in J. Org. Chem., 32, 2376 (1967) or Bull. Soc. Chem. Fr., (1975), 592. Examples of solvents, which are not critical, are the same as those employed in step C2 of Method C, especially the alcohols.
Compounds of the invention in which the thienopyrimidine or furopyrimidine part of the compound of formula (XV) has the partial formula (If) or (Ih) can be prepared by a corresponding reaction starting with a compound of formula (XVI), in place of the compound of formula (XIII): ##STR14##
Step D2
The resulting compound of formula (XIV), with or without isolation from the reaction mixture, is then treated with a base, to catalyse its rearrangement to the desired compound of formula (XV).
There is no particular restriction on the nature of the base employed, provided that it does not have any adverse effect on other parts of the molecule. Suitable bases include: alkali metals, such as sodium or potassium; and alkali metal alkoxides, such as sodium methoxide or sodium ethoxide.
The reaction will take place over a wide range of temperatures, although we generally prefer to carry it out with heating, in order to accelerate it. In general, a reaction temperature between room temperature and the reflux temperature of the solvent is preferred.
METHOD E
Compounds of the invention in which R.sup.6 represents a group of formula --CH.sub.2 --W and W represents a group of formula ##STR15## that is to say compounds of formula (XIX), can be prepred as illustrated in the following reaction scheme: ##STR16##

This reaction consists of reacting the compound of formula (XVII) (which may have been prepared following the procedures described in Method A) with a diol, dithiol or thioalcohol of formula (XVIII) in the presence of an acid catalyst. There is no particular limitation on the nature of the acid catalyst employed and any acid which does not react with either of the two reagents may be employed. Examples include: alkanesulfonic acids in which the alkane part may be unsubstituted or have one or more halogen substituents, such as methanesulfonic acid, ethanesulfonic acid or trifluoromethanesulfonic acid; arenesulfonic acids, such as benzenesulfonic acid or p-toluenesulfonic acid; and mineral acids, such as sulfuric acid or hydrochloric acid.
The reaction is preferably effected in the presence of a solvent, the nature of which is not critical, provided that it has no adverse effect upon the reaction. Examples of suitable solvents include aromatic, aliphatic and cycloaliphatic hydrocarbons, which may or may not be halogenated (e.g. chlorinated), such as benzene, toluene, xylene, methylnaphthalene, chlorobenzene, dichlorobenzene, methylene chloride, chloroform, 1,2-dichloroethane, trichloroethylene or cyclohexane.
The reaction will take place over a wide range of temperatures and the precise reaction temperature chosen is not particularly critical. In general, however, we prefer to carry out the reaction at a temperature not less than room temperature and not more than the boiling temperature of the solvent employed. However, as is apparent from the reaction illustrated above, water is eliminated in this reaction and it is, therefore, preferred to carry out the reaction at the azeotropic point of water and the solvent, in order to remove water from the reaction system and thereby facilitate the reaction.

The reaction is effected by reacting the compound of formula (XX) with a thionyl halide, sulfinyl halide or sulfonyl halide of formula (XXIII) in the presence of an organic base.
There is no particular restriction on the nature of the organic base to be employed, since its principal function is to react with and eliminate from the reaction system the hydrogen halide generated by the reaction. Suitable organic bases include pyridine, triethylamine and N,N-dimethylaniline.
The reaction is preferably effected in the presence of a solvent, the nature of which is not critical, provided that it has no adverse effect on the reaction. Suitable solvents include, for example: aromatic, aliphatic and cycloaliphatic hydrocarbons, which may or may not be halogenated (e.g. chlorinated), such as benzene, toluene, xylene, methylnaphthalene, petroleum ether, ligroin, hexane, chlorobenzene, methylene chloride, chloroform, 1,2-dichloroethane, trichloroethylene and cyclohexane; and ethers such as diethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran and dioxane.
The reaction will take place over a wide range of temperatures, and the precise temperature chosen is not particularly critical to the reaction. Generally, we will carry out the reaction at a temperature or temperatures within the range from 0.degree. C. to the boiling point of the solvent employed. Most preferably, the reaction mixture is cooled whilst the thionyl, sulfinyl or sulfonyl halide (XXIII) is added dropwise, and then, when the dropwise addition is complete, the reaction mixture is heated.

The reaction is preferably effected in the presence of a solvent, the nature of which is not critical, provided that it has not adverse effect upon the reaction. The solvent is preferably water-miscible, and examples of suitable solvents include: alcohols, such as methanol or ethanol; and ethers, such as dioxane or tetrahydrofuran. The alcohols are preferred.
The reaction is preferably effected in the presence of a base, preferably an inorganic base, such as an alkali metal hydroxide (e.g. sodium or potassium hydroxide) or an alkali metal carbonate (e.g. sodium or potassium carbonate), of which the hydroxides are preferred.

Examples of suitable solvents include: ethers, such as diethyl ether or ethylene glycol dimethyl ether; ketones, such as acetone or methyl ethyl ketone; and dimethylformamide.
The reaction is also preferably effected in the presence of a base, the major function of which is to react with and thus eliminate from the reaction system the hydrogen halide HX produced in the course of the reaction. Any base capable of doing this without interfering with the reaction may be employed. Suitable bases include: alkali metals, such as sodium or potassium; alkali metal hydrides, such as sodium hydride or potassium hydride; alkali metal amides, such as sodium amide; and alkali metal carbonates, such as sodium carbonate or potassium carbonate.
The reaction will take place over a wide range of temperatures and the precise temperature chosen is not particularly critical. We generally prefer to carry out the reaction at a temperature within the range from room temperature to the boiling point of the solvent, preferably with heating.
