## Abstract Enzymatic hydrolysis of (Β±)‐2,4,4‐trimethyl‐2‐cyclohexenyl acetate [(Β±)‐3] with pig liver esterase yielded (__R__)‐(+)‐2,4,4‐trimethyl‐2‐cyclohexen‐1‐ol [(__R__)‐2] and unchanged (__S__)‐(βˆ’)‐acetate (__S__)‐3. Enantiomerically pure (__S__)‐2 was converted into (__R__)‐dihydro‐α‐ionone (
