1-Acyl-2,6,6-trimethylcyclohexene derivatives, processes for producing same, intermediates therefor and organoleptic uses thereof

摘要

Process intermediates are described herein having the generic structure: <IMAGE> wherein X is selected from the group consisting of chloro, bromo and iodo; R3 is hydrogen or does not represent any group; wherein one of the wavy lines is a carbon-carbon double bond and the other of the wavy lines is a carbon-carbon single bond; with the proviso that when the DELTA 2,3 bond is a carbon-carbon double bond, then R3 is hydrogen and R3 and the moiety: <IMAGE> are so juxtaposed that the molecule having the structure: <IMAGE> exists in two different isomeric forms; a "+" form and "-" form.
