Significance
The use of α-keto esters as nucleophiles in conjugate addition is uncommon because of their high electrophilicity and thus predisposition to self-condensation. This work describes an application of a dinuclear nickel catalyst to address this problem, yielding syn products in moderate to good yields and enantioselectivities. This work is preceded by a report from the Sodeoka group (J. Am. Chem. Soc, 2010, 132, 4036), where similar products are obtained in high anti selectivity.
