%X The unsaturated lactone (2) derived from manool (1) has a particularly rigid 10-membered ring which gives rise to high asymmetric induction in epoxidation with m-chloroperoxybenzoic acid. The corresponding 11-membered lactone (14) shows greater flexibility. The conformations of lactone (2) and epoxy lactones (12) and (13) have been determined by X-ray diffraction studies.
