CARBAMOYL CARBOXYLIC ACID HYDRAZIDES AND THEIR USE AGAINST FUNGI.

摘要

Disclosed are carbamoyl carboxylic acid hydrazides (I) and their salts, wherein: R1 is optionally substitued alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heteroaryl or an optionally substituted non-aromatic carbo- or heterocycle, W1W2C=N-, where W1 is optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heteroaryl and W2 is hydrogen or W1; R2 is hydrogen or optionally halogenated alkyl or cycloalkyl; R3 is optionally substituted alkyl, cycloalkyl or phenylalkyl; R4 is hydrogen or one of the R3 radicals, or R3 and R4 together with the C atom to which they are bound form an optionally substituted saturated carbo- or heterocycle; R5 is one of the R2 radicals; R6 is optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heteroaryl, an optionally sustituted non-aromatic carbo- or heterocycle or, when R3 = isopropyl, hydrogen; R7 is one of the R6 radicals except hydrogen; X1, X2 and X3 are in each case oxygen or sulfur. Disclosed also are methods for their preparation, agents that contain them, their use and intermediate products (IV), wherein X3 is oxygen and R3 is a CH(CH3)2, CH2CH(CH3)2 or CH(CH3)C2H5 group.
