  摘要：

  The utility of the Claisen rearrangement using carefully separated, diastereoisomeric allylic alcohols (1a) and (1b) in the preparation of (+/-)-Z-geissoschizol (4a), (+/-)-3-epi-Z-geissoschizol (4b), (+/-)-corynantheidol (7a), (+/-)-dihydrocorynantheol (8a), (+/-)-3-epi-dihydrocorynantheol (8b) and the corresponding corynan-17-oic acid methyl esters (3a, 3b, 5a, 6a and 6b) is shown. Special attention is paid to the stereochemical outcome of catalytic (PtO2) hydrogenation of the C(20) Z-ethylidene side chain.
