A convergent and efficientsynthesis of a marine natural product, nakienoneB (1), was achieved using a new protocol for α-alkenylation of enonesinvolvingPd-catalyzedcoupling 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.
