Abstract
A convergent and efficient synthesis of a marine natural product, naki enone B (1), was achieved using a new protocol for a-alkenylation of e nones involving Pd-catalyzed coupling of alkenylzincs with alkenyl iod ides. This protocol features (i) avoidance of acidic conditions and (i i) flexibility in charge affinity pattern with respect to the two aken yl groups to be coupled. Copyright (C) 1996 Elsevier Science Ltd
