A copper-catalyzed asymmetric decarboxylative propargylic alkylation of enol carbonates has been realized, allowing for the highly stereoselective formation of acyclic vicinal tri- and tetrasubstituted stereocenters. With this strategy, a series of optically active quaternary α-amino acid esters with an adjunct chiral tertiary propargylic moiety have been prepared from propargyl azlactone-enol carbonates
