Abstract

A concise asymmetric synthesis of chiral bicyclic lactams combining a highly stereoselective 1,2-addition on SAMP hydrazones with a ring closure metathesis has been achieved. The synthetic utility of this approach has been emphasized by the total synthesis of (-)-coniceine in high enantiomeric excess.
