A convergent and efficient synthesis of a marine natural product, nakienone B (1), was achieved using a new protocol for α-alkenylation of enones involving Pd-catalyzed coupling of alkenylzincs with alkenyl iodides. This protocol features (i) avoidance of acidic conditions and (ii) flexibility in charge affinity pattern with respect to the two akenyl groups to be coupled.
