The asymmetric allylic alkylation (AAA) of alpha-aryl gamma-lactones involving the activation of Morita-Baylis-Hillman (MBH) carbonates by an original chiral Lewis base is reported. A wide range of gamma-lactones bearing a quaternary stereocentre was thus obtained in both high yields and high enantiomeric ratios. The direct alkylation by MBH alcohol usingin situactivation has been also established. Additionally synthetically useful functional transformations of groups surrounding the quaternary stereocentre have been performed.
