Stereodivergent synthesis of the 2,3,5,6-tetrasubstituted piperidine ring system: An application to the synthesis of alkaloids

Stereodivergent synthesis of the 2,3,5,6-tetrasubstituted piperidine ring system has been achieved by sequential stereocontrolled Michael-type conjugate addition reaction of appropriate enaminoesters. This methodology has been applied to the total synthes
