  Diastereoselective Alkynylation of N-p-Tolylsulfinylimines with Aluminum Acetylides

  摘要：

  The addition of alkynyl dimethyl aluminum compounds onto N-p-tolylsulfinylimines was investigated. The reaction was proved to be totally regioselective, leading to propargylamines with high diastereoselectivity (up to 99% de). Addition of aluminum derivatives gave a reversal of diastereoselectivity compared to the addition reaction of lithium acetylide.
