Enantioselective Alkenylation via Nickel-Catalyzed Cross-Coupling with Organozirconium Reagents

Abstract

A new family of organometallic compounds, organozirconium reagents, are shown to serve as suitable partners in cross-coupling reactions of (activated) secondary alkyl electrophiles. Thus, the first catalytic method for coupling secondary α-bromoketones with alkenylmetal reagents has been developed, specifically, a mild, versatile, and stereoconvergent carbon−carbon bond-forming process that generates potentially labile β,γ-unsaturated ketones with good enantioselectivity.
