Also included in the invention are methods for the procurement of said substituted 1,3-diazolyl-2-propanols, compositions containing said antimycotic compounds and methods for the use of said compounds and compositions for treatment of mycoses.

Description

The present invention relates to new substituted 1,3-diazolyl-2-propanols, a process for their preparation and their use as antimycotics.

It has already been disclosed that certain diazolyl derivatives have antimycotic properties.

New substituted 1,3-diazolyl-2-propanols of the formula ##STR1## in which Alk.sup.1 represents straight-chain or branched alkyl and

Alk.sup.2 represents straight-chain or branched alkyl, or Alk.sup.1 and Alk.sup.2 together represent a cycloaliphatic ring, X represents a nitrogen atom or the CH group, Y represents a nitrogen atom or the CH group and R represents in each case optionally substituted phenyl, phenylalkyl, phenoxy, phenylthio, phenoxyalkyl, phenylthioalkyl, benzyloxy or benzylthio, and physiologically acceptable acid addition salts thereof, have been found.

It has furthermore been found that the substituted 1,3-diazolyl-2-propanols of the formula (I) are obtained by a process in which 2-azolylmethyl-oxiranes of the formula ##STR2## in which

Alk.sup.1, Alk.sup.2, R and X have the abovementioned meaning, are reacted with azoles of the formula ##STR3## in which

Y has the abovementioned meaning, in the presence of a diluent and, if appropriate, in the presence of a base.

If appropriate, an acid can then be added onto the compounds of the formula (I) thus obtained.

The new substituted 1,3-diazolyl-2-propanols of the formula (I) have powerful antimycotic properties.

In addition, the new substituted 1,3-diazolyl-2-propanols are interesting intermediates.

Thus, for example, the compounds of the formula (I) can be converted into the corresponding ethers on the hydroxyl group in the customary manner. Furthermore, acyl or carbamoyl derivatives of the compounds of the formula (I) can be obtained by reaction with, for example, acyl halides or carbamoyl chlorides in a manner which is known in principle. These derivatives have the same antimycotic properties as the hydroxy compounds.

Moreover, the compounds of the formula (I) in which R represents in each case optionally substituted phenylthio, phenylthioalkyl or benzylthio can be oxidised to the corresponding SO or SO.sub.2 derivatives in the customery manner. They have antimycotic properties, too.

Formula (I) provides a general definition of the substituted 1,3-diazolyl-2-propanols according to the invention. Preferably, in this formula Alk.sup.1 represents straight-chain or branched alkyl with 1 to 3 carbon atoms; and Alk.sup.2 represents straight-chain or branched alkyl with 1 to 3 or 4 carbon atoms; or Alk.sup.1 and Alk.sup.2 together represent a 3-membered to 7-membered cycloaliphatic ring, X represents a nitrogen atom or the CH group; Y represents a nitrogen atom or the CH group; and R represents phenyl, phenylalkyl with 1 to 4 carbon atoms in the alkyl part, phenoxy, phenylthio, phenoxyalkyl with 1 to 4 carbon atoms in the alkyl part, phenylthioalkyl with 1 to 4 carbon atoms in the alkyl part, benzyloxy or benzylthio, each of which is optionally mono-, di- or tri-substituted in the phenyl part by identical or different substituents, preferred substituents which may be mentioned being: halogen, alkyl with 1 to 4 carbon atoms, alkoxy and alkylthio with in each case 1 to 4 carbon atoms, halogenoalkyl, halogenoalkoxy and halogenoalkylthio with in each case 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms, such as, preferably, fluorine and chlorine atoms, nitro, cyano, hydroxyl, hydroxycarbonyl, alkoxycarbonyl with 1 to 4 carbon atoms in the alkyl part, hydroximinoalkyl or alkoxyiminoalkyl with 1 to 4 carbon atoms in each alkyl part, and phenyl, phenoxy, benzyl and benzyloxy, each of which is optionally substituted by halogen and/or alkyl with 1 or 2 carbon atoms.

Particularly preferred compounds of the formula (I) are those

in which Alk.sup.1 represents methyl or ethyl; and Alk.sup.2 represents methyl or ethyl; or Alk.sup.1 and Alk.sup.2, together with the carbon atom to which they are bonded, represent cyclobutyl, cyclopentyl or cyclohexyl, X represents a nitrogen atom or the CH group; Y represents a nitrogen atom or the CH group; and R represents phenyl, benzyl, phenethyl, phenoxy, phenylthio, phenoxymethyl, phenoxyethyl, phenylthiomethyl, phenylthioethyl, benzyloxy or benzylthio, each of which is optionally mono- or di-substituted in the phenyl part by identical or different substituents, substituents which may be mentioned being: fluorine, chlorine, bromine, methyl, isopropyl, tert.-butyl, methoxy, methylthio, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, nitro, cyano, hydroxyl, hydroxycarbonyl, methoxycarbonyl, ethoxycarbonyl, hydroximinomethyl, 1-hydroximinoethyl, methoximinomethyl, 1-methoximinoethyl, and phenyl, phenoxy, benzyl and benzyloxy, each of which is optionally substituted by fluorine, chlorine or methyl.

If, for example, 2-(2,4-dichlorophenyl-tert.-butyl---2--(1,2,4-triazol-1-yl-methyl)-oxirane and 1,2,4-triazole are used as starting substances, the course of the process according to the invention can be represented by the following equation: ##STR4##

Formula (II) provides a general definition of the oxiranes to be used as starting substances for carrying out the process according to the invention. In this formula, Alk.sup.1, Alk.sup.2, R and X preferably have those meanings which have already been mentioned as preferred for these substituents in connection with the description of the substances of the formula (I) according to the invention.

The oxiranes of the formula (II) are known (compare DE-OS (German Published Specification) 3,111,238 corresponding to U.S. patent application Ser. No. 325,689 filed Feb. 26, 1982 now pending; or they are the subject of earlier applications which have been filed by the Applicant Company and have not yet been published (compare German Patent Applications P 32 02 601 of 1/22/82 and P 32 37 400 of 10/8/82); or they can be obtained in a generally known manner, by reacting azolyl-ketones of the formula ##STR5## in which

Alk.sup.1, Alk.sup.2, R and X have the abovementioned meaning, either (.alpha.) with dimethyloxosulphonium methylide of the formula ##STR6## in a manner which is known per se in the presence of a diluent, such as, for example, dimethylsulphoxide, at temperatures between 20.degree. C. and 80.degree. C. (in this context, note J. Am. Chem. Soc. 87, 1363-1364 (1965)). or (.beta.) with trmethylsulphonium methyl-sulphate of the formula ##STR7## in a manner which is known per se, in the presence of an inert organic solvent, such as, for example, acetonitrile, and in the presence of a base, such as, for example, sodium methylate, at temperatures between 0.degree. C. and 60.degree. C., preferably at room temperature (note also Heterocycles 8, 397 (1977)).

If appropriate, the oxiranes of the formula (II) thus obtained can be further reacted directly, without being isolated.

The azolyl-ketones of the formula (IV) are known compare DE-OS (German Published Specification) 3,111,238, corresponding to U.S. patent application Ser. No. 352,689 filed 2/26/82, or they can be prepared by processes which are known in principle.

Formula (III) provides a general definition of the azoles also to be used as starting substances for the process according to the invention. In this formula, Y preferably has the meanings which have already been mentioned for this substituent in the definition of the invention.

Possible diluents for the process according to the invention are organic solvents which are inert under the reaction conditions, these include, preferably, alcohols, such as, C.sub.1 -C.sub.3 -alkanols or alkoxy alkanols, for example, ethanol, methoxyethanol or propanol; ketones, such as, C.sub.2 -C.sub.4 -alkyl ketones, for example, 2-butanone; nitriles, such as, for example, acetonitrile; esters, such as C.sub.1 -C.sub.4 -alkyl esters of C.sub.1 -C.sub.4 -alkane carboxylic acids such as, for example, ethyl acetate; ethers, such as, for example, dimethyl or diethyl ether dioxane; aromatic hydrocarbons, such as, for example, benzene and toluene; or amides, such as, for example, dimethylformamide.

Possible bases for the reaction according to the invention are all the inorganic and organic bases which can customarily be used. These include, preferably, alkali metal carbanates, such as, for example, sodium carbonate and potassium carbonate; alkali metal hydroxides, such as, for example, sodium hydroxide, ammonium bases, alkali metal alcoholates, such as, for example, sodium ethylate and ethylate and potassium ethylate and ethylate; alkali metal hydrides, such as, for example, sodium hydride; and lower tertiary alkylamines, cycloalkylamines and aralkylamines, such as, in particular, triethylamine.

The reaction temperatures can be varied within a substantial range in carrying out the process according to the invention. In general, the reaction for all reaction steps is carried out at temperatures between 0.degree. C. and 200.degree. C., preferably between 60.degree. C. and 150.degree. C.

In carrying out the process according to the invention, 1 to 2 moles of azole of the formula (III) and, if appropriate, 1 to 2 moles of base are preferably employed per mole of oxirane of the formula (II); the end products are isolated in the generally customary manner.

The compounds of the formula (I) can also be obtained by reacting diazolyl-ketones of the formula ##STR8## in which

X and Y have the abovementioned meaning, with a Grignard reagent of the formula ##STR9## in which

Alk.sup.1, Alk.sup.2 and R have the abovementioned meaning,

The acid addition salts of the compounds of the formula (I) can be obtained in a simple manner by customary salt formation methods, for example by dissolving a compound of the formula (I) in a suitable inert solvent and adding the acid, for example hydrochloric acid, and they can be isolated in a known manner, for example by filtration, and if appropriate purified by washing with an inert organic solvent.

The compounds of the formula (I) which can be used according to the invention and their acid addition salts display antimicrobial actions, in particular powerful antimycotic actions. They possess a very broad antimycotic action spectrum, especially against dermatophytes and blastomyces as well as biphase fungi, for example against varieties of Candida, such as Candida albicans, varieties of Epidermophyton, such as Epidermophyton floccosum, varieties of Aspergillus, such as Aspergillus niger and Aspergillus fumigatus, varieties of Trichophyton, such as Trichophyton mentagrophytes, varieties of Microsporon, such as Microsporon felineum and varieties of Torulopsis, such as Torulopsis glabrata. The listing of these micro-organisms in no way implies a limitation of the germs which can be combated but is only of illustrative character.

Examples which may be mentioned of fields of indication in medicine are: dermatomycoses and systemic mycoses, especially those caused by Trichophyton mentagrophytes and other varieties of Trichophyton, varieties of Microsporon, Epidermophyton floccosum, blastomyces and biphase fungi as well as moulds.

The active compounds or the pharmaceutical formulations can be administered locally, orally, parenterally, intraperitoneally and/or rectally, preferably parenterally, and in particular intravenously. In general, it has proved advantageous to administer the active compound or compounds according to the invention topically, orally or parenterally in total amounts of about 10 to about 300, preferably 50 to 200, mg/kg of body weight every 24 hours, optionally in the forms of several individual administration, in order to achieve the desired results. However, it can be necessary to deviate from the dosages mentioned, and in particular to do so as a function of the species and the body weight of the subject to be treated, the nature and severity of the disease, the nature of the formulation and of the administration of the medicament and the time or interval over which the administration takes place. Thus it can in some cases suffice to manage with less than the abovementioned amount of active compound, whilst in other cases the abovementioned amount of active compound must be exceeded. The particular optimum dosage required and the type of administration of the active compounds can easily be determined by anyone skilled in the art on the basis of his expert knowledge.
