1(1,3-Dioxobutane)-3,3-dimethylcyclohexane useful in perfumes

Abstract

Described is a process for preparing the compound having the structure: ##STR1## comprising the steps of reacting 1-acetyl-3,3-dimethylcyclohexane having the structure: ##STR2## with an alkyl acetate defined according to the structure: ##STR3## wherein R.sub.2 is C.sub.1 -C.sub.5 alkyl such as methylethyl, n-propyl, i-propyl, n-butyl, 2-butyl and tertiary butyl, thereby forming a diketone having the structure: ##STR4## reacting the said diketone with an allyl halide having the structure: ##STR5## (wherein X represents bromo or iodo) to form a substituted diketone having the structure: ##STR6## and then transforming the compound having the structure: ##STR7## into the compound having the structure: ##STR8## by means of a retro-Claisen reaction. Also described is the use in augmenting or enhancing the aroma of perfume compositions, colognes or perfumed articles of the compound having the structure: ##STR9##
