Synthetic studies on biscembranoids: asymmetric total synthesis of methyl sarcoate
摘要:
The asymmetric total synthesis of a marine natural product, methyl sarcoate, has been achieved featuring the asymmetric Michael addition, the dithiane coupling, the Kosugi-Migita-Stille coupling, and the ring-closing metathesis. (C) 2005 Elsevier Ltd. All rights reserved.

Various highly stereoselective asymmetric reactions based on chiral diamines having pyrrolidine ring are described. Some of these reactions have been successfully applied to the syntheses of natural products.

Total Synthesis of Methyl Sarcophytoate, a Marine Natural Biscembranoid
The total synthesis of methyl sarcophytoate (1), a marine natural biscembranoid, has been achieved by the thermalDiels−Alderreaction between the 14-membered dienophile unit, methyl sarcoate (2), and the 14-membered diene unit 64. Methyl sarcoate (2) was prepared using n-BuLi-Bu2Mg-mediated dithiane coupling, Kosugi−Migita−Stille coupling, and Grubbs ring-closing metathesis. The diene unit 64 was
