Intramolecular homolyticsubstitution (SHi) on the sulfuratom at acyclic N-(o-bromobenzyl)sulfinamides takes place with a complete inversion of the configuration and provides an excellent tool to connect N-tert-butanesulfinylimines with enantiopure 3-substituted benzo-fused sulfinamides (1,2-benzoisothiazoline 1-oxides) and the related pharmacologically relevant sulfonamides.
