    Display omitted We report herein a new pyrazolidinone chiral auxiliary and its utility in Lewis acid-mediated conjugate addition followed by diastereoselective trapping of the intermediate radical by an allyl group. The allylated products were obtained in good yields (up to 89%) and high diastereoselectivities (up to 94/6).
