  First total synthesis of (+)-vedelianin, a potent antiproliferative agent

  摘要：

  The total synthesis of (+)-vedelianin has been accomplished in 18 steps from vanillin. Preparation of a key intermediate in nonracemic form through a Shi epoxidation has allowed determination of the absolute stereochemistry of the natural product as the (25,3R,4aR,9aR)-isomer.
