An asymmetric synthesis of mexiletine and structural analogs was developed using chiral tert-butanesulfinamide to convert precursor ketones to chiral amines. Starting from α-aryloxy ketones, a two-step condensation–reduction procedure provided chiral N-tert-butanesulfinyl amines as immediate precursors to mexiletine or structural analogs. Reduction of the intermediate N-tert-butanesulfinyl imine showed
