alpha-keto esters is described using a copper(II)-catalyzed aerobic deacylation of substituted acetoacetate esters. The substrates for the title process arise from catalytic, enantioselectiveconjugateadditions and alkylation reactions of acetoacetate esters. The mild conditions do not induce racemization of the incipient enolizable alpha-keto ester. The reaction is tolerant of esters, certain ketones
