Enantioselective allylic substitution of Morita–Baylis–Hillman (MBH) acetates with phthalimide was realized in the presence of a novel l-proline-derived chiral trifunctional phosphine amide ligand to give the corresponding allylicamination adducts in good yields (70–95%) and in modest to good enantioselectivities (34–78% ee’s).
