A Highly Efficient, Selective, and General Method for the Synthesis of Conjugated (all-E)-Oligoenes of the (CHCH)n Type via Iterative Hydrozirconation−Palladium-Catalyzed Cross-Coupling

[reaction: see text] A linear iterative method for the construction of (all-E)-oligoenes of the (CH=CH)n type via hydrozirconation-palladium-catalyzed cross-coupling with (E)-1-bromo-4-trimethylsilyl-1-buten-3-yne is described. This method promises to provide an efficient, selective, and general route to oligoene macrolide antibiotics and other related natural products.
