A photoinduced chemo-, site- and stereoselective α-C(sp3)−H functionalization of sulfides was demonstrated using isatins as the photoredox reagent and coupling partner catalyzed by a chiral gallium(III)-N,N′-dioxide complex. This cross-coupling protocol is highly selective for the direct late-stage functionalization of methionine-related peptides, regardless of the inherent structural similarity and
