Process for the production of 1-crotonoyl-2,6,6-trimethylcyclohexa-1,3-diene and esters of alkynylcyclohexane derivatives as intermediates therefor

A novel method of preparing 1-crotonoyl-2,6,6-trimethylcyclohexa-1,3-diene comprises treating an ester of the formula with a proton acid under essentially anhydrous conditions. The method involves the use of certain new substituted 2,6,6-trimethylcyclohexane derivatives.
