  First synthesis and determination of the absolute stereochemistry of iso-cladospolide-B and cladospolides-B and C

  摘要：

  The syntheses of iso-cladospolide-B, cladospolide-B and cladospolide-C are reported with 4S,5S,11S-configuration. Of the three stereogenic centres, the C-4/C-5 vic-diol was created by Evans aldol condensation, while the C-11 stereocentre was created by Jacobsen's method. The synthesis of cladospolides 1-3 defined the absolute stereochemistry of these natural products. (c) 2006 Elsevier Ltd. All rights reserved.
