Synthesis of alkaloid223Ahas been achieved by sequential use of our original conjugate addition reaction to enaminoesters as the key step. The proposed structure for natural223A(A, absolute configuration unknown) was revised toB, and the relative stereostructure was determined to be 5R*,6R*,8R*,9S* by the present synthesis.
