A copper-catalyzed cascade reaction of alpha,beta-unsaturated esters with keto esters is reported. It features a copper-catalyzed reductive aldolization followed by a lactonization. This method provides a facile approach to prepare gamma-carboxymethyl-gamma-lactones and delta-carboxymethyl-delta-lactones under mild reaction conditions.
