✦ Synopsis

A concise enantiocontrolled synthesis of the enamine-aminal heterocyclic core found in the zoantharnine alkaloids is presented. Conjugate addition of a chiral imine provides for excellent diastereofacial selectivity in the generation of the quaterna~. Cgasymmetry of 4.

Stereocontrolled construction of the fully functionalized heterocyclic aminal core (CDEFG ring) of the zoanthamine and norzoanthamine family was successfully accomplished from the monocyclic ketoacid which was prepared from ( + )-Wieland-Miescher ketone and D-glutamic acid.
