Abstract

A new dinuclear zinc cooperative catalytic enantioselective three-component reaction via a domino Knoevenagel /Michael/cyclization sequence has been developed. A series of chiral 3,3′-dihydrofuran spirooxindoles are obtained in excellent yields (up to 99%) and enantioselectivities (up to 99% ee). In addition, the reaction is carried out smoothly on a gram scale under mild conditions.
