Remarkably Selective Formation of Allenyl and Dienyl Alcohols via Ni-Catalyzed Coupling Reaction of Conjugated Enyne, Aldehyde, and Organozinc Reagents
conjugated enynes, aldehydes, and organozincreagents to form unsaturated alcohols. Ligand effects dramatically control the regioselectivity in these Ni-catalyzed MCRs, leading to the selective formation of allenyl alcohols and conjugated dienyl alcohols. A nickel catalyst promotes the multi-component reactions (MCRs) of conjugated enynes, aldehydes, and organozincreagents to form unsaturated alcohols
