[摘要]:The first enantioselective total synthesis of aspergillide C (I), a cytotoxic 14-membered macrolide isolated from the marine-derived fungus Aspergillus ostianus, has been accomplished from a com. available chiral glycidol deriv. by a 12-step sequence involving an expeditious prepn. of a cyclic acetal intermediate and a trans-selective Ferrier-type two-carbon homologation reaction. |
