  Anti Aldol Selectivity in a Synthetic Approach to the C₁−C₁₂ Fragment of the Tedanolides

  摘要：

  In a synthetic approach to the completely protected C-1-C-12 fragment of the macrocyclic cytotoxic agent tedanolide 1, we carried out the tin-catalyzed Mukaiyama aldol reaction between the 2,3-dialkoxypropanal 5 and the silyl enol ether 6 derived from the ketone 7, which gave, unexpectedly, the anti aldol isomer, rather than the expected syn isomer 4, as the major diastereomer formed.
