This work describes the enantioselective preparation of (R)-(+)-isocarvone, (S)-(-)-5-isopropenylcyclohex-2-enone and (S)-(-)-3-isopropenylcyclohexanone starting from (S)-(-)-perillaldehyde. These compounds hold the prospect of serving as useful chiral building blocks or intermediates in organic synthesis.
