  Enantioselective synthesis of an ent-trichothecene

  摘要：

  A convergent route for the enantioselective synthesis of trichothecenes is described. A key step in the synthetic sequence is an Ireland-Claisen rearrangement that occurs with total facial selectivity and high diastereoselectivity. The relative stereochemistry about the vicinal quaternary centers of the major diastereomer is that of the trichothecene skeleton, but the absolute stereochemistry is opposite to that of the natural products.
