  Enantioselective total synthesis of aigialomycin D

  摘要：

  An efficient, convergent approach for the total synthesis of aigialomycin D I is described. Key features of the synthetic strategy include (a) a Sharpless asymmetric epoxidation reaction and selective opening of a 2,3-epoxy alcohol to elaborate the two hydroxy-bearing stereogenic centers at the C5' and C6' positions; (b) a Kocienski modified Julia protocol to construct the two E-configured double bonds; and (c) Yamaguchi macrolactonization to acccess the 14-membered macrocyclic ring.
