A nucleophilic activation of elemental sulfur by thiols enables a mild and chemoselective thioacylation of amines with α-keto acids and elemental sulfur. The reaction tolerates a broad range of functional groups, including unprotected hydroxyl, carboxyl, amide, sulfide, and tertiary amine moieties.
