  Highly Efficient Stereocontrolled Synthesis of Danishefsky’s Taxol CD Ring Key Intermediate

  摘要：

  Danishefsky's taxol CD ring key intermediate is synthesized in 15 steps and 11.4% overall yield from a readily available starting material. Absolute stereochemistry of the starting material and stereocontrolled steps determine the absolute configuration of the five requisite contiguous stereocenters.
