  Stereoselective Synthesis of the C₅–C₁₈ Fragment of Halichomycin

  摘要：

  An efficient and convergent synthesis of the C-5-C-18 fragment of halichomycin is reported. Butanolide fragment 6 was readily prepared stereoselectively from (R)-Roche ester through catalyst control; dienylic bromide domain 7 was synthesized from (S)-serine by substrate control. C-5-C-18 fragment 2 was rapidly assembled through a stereoselective alkylation of the butanolide with the dienylic bromide, followed by functional group transformations.
