In an enantioselective iridium-catalyzed allylic alkylation reaction of a masked acyl cyanide (MAC) reagent, the umpoled MAC synthon serves as a carbon monoxide equivalent. The reaction proceeds with good yield and excellent selectivity up to gram scale for a wide range of substituted allylic electrophiles to provide enantioenriched vinylated α-aryl carbonyl derivatives.
