A first total synthesis of callystatin A (1), a potent cytotoxic polyketide from the marine sponge Callyspongia truncata, has been achieved by use of an E-selective Wittig olefination and asymmetric Evans aldol condensation as the key reactions. Thus, the absolute stereostructure of 1 previously established by us was confirmed. (C) 1998 Elsevier Science Ltd. All rights reserved.
