(a') A catalytic hydrogenation of 3,3-dimethyl-cyclohex-5-en-1-one was carried out according to the usual techniques in the presence of palladium on charcoal and yielded 3,3-dimethyl-cyclohexanone. The subsequent ethylination by means of acetylene in a basic medium gave 1-ethynyl-1-hydroxy-3,3-dimethyl-cyclohexane in about 50% yield.
