摘要

Three segments A, B and C for okadaic acid synthesis were coupled with each other in the order of A+ (B+ C), the key steps of the twice couplings being between sulfone carbanions and aldehydes. After the B+ C coupling, the asymmetric center C-27 was generated by a hydride reduction of the corresponding ketone 16 under electronic control. The second coupling was followed to form the C-14 15 double bond. Oxidation of the α-oxy aldehyde ...
