Peptidecouplingreagents can be used as versatile reagents for the formation of aliphatic isothiocyanates and thioureas on solidphase from the corresponding solid-phase anchored aliphatic primary amines. The formation of the thioureas is fast and highly chemoselective, and proceeds via formation of the intermediate isothiocyanate. The isothiocyanate and subsequent thiourea formation take place under
