Get PDFA 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 carbonâcarbon bond-forming process that generates potentially labile ÎČ,Îł-unsaturated ketones with good enantioselectivity.National Institute of General Medical Sciences (U.S.) (grant R01-GM62871)Novartis (Firm)Merck Research Laboratorie
