[structure: see text] Synthesis of alkaloid 223A has been achieved by sequential use of our original conjugate addition reaction to enaminoesters as the key step. The proposed structure for natural 223A (A, absolute configuration unknown) was revised to B

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
