Abstract

In the presence of a Pd catalyst and excess boric acid, a range of α-unbranched primary allylic amines were smoothly substituted with sodium sulfinates in an α-selective fashion to give structurally diverse allylic sulfones in good to excellent yields with exclusive E selectivity. Use of BINOL as a ligand allowed the transformation of unsymmetric α-chiral primary allylic amines in good to excellent yields with excellent retention of ee.
