Decarbonylative cross-coupling of cyclic anhydrides: Introducing stereochemistry at an sp3 carbon in the cross-coupling event

Treatment of cyclic anhydrides with stoichiometric amounts of nickel-neocuproine complex generates alkylcarboxylato-nickelalactones upon extrusion of CO. These metalacycles undergo cross-coupling with arylzinc reagents. The generated CO is sequestered in situ by a nickel-dppb complex. The overall sequence effects a secondary sp3(electrophile)-sp2(nucleophile) cross-coupling and allows for control of stereochemistry during the bond-forming event. Copyright
