(Chemical Equation Presented) Peptide-based chiral ligands, readily prepared from commercially available materials, are used to promote Cu-catalyzed asymmetric allylic alkylations of α,β-unsaturated esters bearing a γ-phosphate with various alkylzinc reagents. These transformations lead to the formation of α,α′-dialkyl-β,γ-unsaturated esters in high yields as well as high regio- (re) and enantloselectivities (ee).
