  Stereoselective synthesis of 2-epi-jaspine B via base-catalyzed intramolecular oxy-Michael conjugate addition approach

  摘要：

  2-epi-Jaspine B has been synthesized starting from (-)-diethyl tartrate in 12 simple steps and 26.6% overall yield. The key intermediate was obtained via stereoselective base-catalyzed intramolecular oxy-Michael conjugate addition followed by tandem hydrogenation/hydrogenolysis. (c) 2009 Elsevier Ltd.
