The asymmetric α-oxylation of the dienolates derived from chiral α, β- or β, γ-unsaturated imide with dibenzyl peroxydicarbonate followed by the Pd(0)-catalyzed reactions of the resulting allylic carbonate with various nucleophiles (alkylation, etherification, and amination) is shown to provide the γ-(S)- or -(R)-configurated α, β-unsaturated imide, respectively, with a high level of stereocontrol
