The first enantioselective [2,3]-Wittig rearrangement of α-(allyloxy)- acetates is described which involves a chiral boron enolate with a chiral bis-sulfonamide ligand to afford the α-hydroxy-β-alkyl-γ,δ-unsaturated esters in a high enantioselectivity (>95%ee), along with a high threo diastereoselectivity.
