  Stereospecific Synthesis of Piperidine Skeleton by [4+2] Cycloaddition, Leading to the Synthesis of Piperidines of Biological Interests

  摘要：

  [4+2] Cycloaddition reaction between a chiral imine possessing an auxiliary derived from tartaric acid and Danishefsky diene was studied, and the reaction promoted by boron trifluoride etherate gave 2,3-dehydropiperidin-4-one in a stereospecific manner. The adduct thus obtained was converted into (S)-coniine derivatives without loss of the stereochemical integrity.
