title = "Asymmetric aza-Michael addition: synthesis of (-)-allosedridine and (-)-2-epi-ethylnorlobelol",
abstract = "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.",
