Herein, access to axially and centrally chiral sulfinamides via asymmetric allylic alkylation was reported. A series of sulfinamides were obtained with good outcomes (up to 99% yield, >19:1 dr, and 98:2 er). The synthetic utility of the reaction was demonstrated by scaled-up synthesis, product transformation, and application as a catalyst in asymmetric catalysis.

An efficient kinetic resolution of sulfinamides via an asymmetric N-allylic alkylation reaction was realized using hydroquinine as a catalyst under mild conditions. The kinetic resolution of a range of Morita−Baylis−Hillman adducts and Naryl tert-butylsulfinamides was highly effective. In addition, the synthetic utility of the protocol was demonstrated by a scaled-up reaction. Density functional theory calculations provide convincing evidence for the interpretation of stereoselection.
