  Asymmetric aza-Michael addition: synthesis of (−)-allosedridine and (−)-2-epi-ethylnorlobelol

  摘要：

  The combination of cross-metathesis and aza-Michael addition is an efficient method for generating piperidine alkaloids. Allosedridine and 2-epi-ethylnorlobelol were synthesized in six steps with ca. 25% overall yield. The aza-Michael addition is reversible for phenyl and alkyl ketones; however, the epimerization is not observed for the corresponding ester and amide. (c) 2008 Elsevier Ltd. All rights reserved.
