  Enantioselective Dreiding-Schmidt reactions: asymmetric synthesis and analysis of α-methylene-γ-butyrolactones

  摘要：

  The zinc/silver-graphite mediated Dreiding-Schmidt reactions between aldehydes and the 2-bromomethyl-acrylate derived sultamamides (+)/(-)-28 or (+)/(-)-30 gave the corresponding substituted alpha-methylene-gamma-butyrolactones with ee's up to 90%. Enantiomerically pure compounds were obtained by semipreparative HPLC using a chiral stationary phase. (C) 1997 Elsevier Science Ltd.
