Abstract

The invention comprises isoxazoles of the general formula <FORM:0938420/IV(a)/1> wherein R is a C1-8 alkyl group and R1 and R11 are the same or different and each represent a hydrogen atom, a C1-8 alkyl group or a phenyl group, or, when linked together with the adjacent carbon atom, a C5 or C6 cycloalkyl group; and of the general formula <FORM:0938420/IV(a)/2> wherein R1 and R11 are the same or different and each represents a hydrogen atom a methyl group or a phenyl group, or, when linked together with the adjacent carbon atom, a cyclohexyl group, and the preparation of the hydrazides by either reacting a hydrazide of the formula <FORM:0938420/IV(a)/3> with R1R11CO and reducing the resulting hydrazone or by reacting a compound of the formula <FORM:0938420/IV(a)/4> (wherein X is a C1-8 alkoxy group) with a hydrazine R1R11CHNHNH2.
