An asymmetric synthesis of N-aryl sulfinamides was achieved through copper-catalyzed coupling reactions of aryl iodides with sulfinamides. Such a kinetic resolution process provided the desired coupling products in moderate to good yields and with moderate enantioselectivities.
The palladium-catalyzed C–N cross coupling of sulfinamides and arylhalides is reported. In the presence of Pd2(dba)3, tBuXPhos, NaOH, and a small amount of water, the C–N cross coupling of chiral tert-butanesulfinamide and arylhalides was accomplished to give N-aryl tert-butanesulfinamide without racemization, and the coupling of racemic p-toluenesulfinamide smoothly afforded N-aryl p-toluenesulfinamides
