Herein, we report a Cu-catalyzed enantioselective allylic alkylation using a γ-butyrolactone-derived silylketeneacetal. Critical to the development of this work was the identification of a novel mono-picolinamide ligand with the appropriate steric and electronic properties to afford the desired products in high yield (up to 96 %) and high ee (up to 95 %). Aryl, aliphatic, and unsubstituted allylic
