  Studies on the total synthesis of the saponaceolides. 2. Enantioselective synthesis of 2-epi-saponaceolide B

  摘要：

  The paper describes an asymmetric convergent synthesis of 2-epi-saponaceolide B, illustrating a general approach to the construction of the saponaceolide structure. The strategic C10'-C11' bond was formed by coupling a lithium salt containing the left part of the molecule with a carbonyl derivative representing the right part. (C) 1999 Elsevier Science Ltd.
