Different pathways in the reaction of N-(tosylmethyl)-substituted ureas, thioureas, and N ‘-cyanoguanidines with sodium cyanide. Synthesis of alpha-ureido nitriles, alpha-ureido amides, and hydantoin imino derivatives

Reaction of N-(tosylmethyl)-substituted ureas, thioureas, and N’-cyanoguanidines, prepared by condensation of the corresponding amides with various aldehydes and p-toluenesulfinic acid, with NaCN has been studied. The outcome of the reaction is strongly dependent on the amide nature and reaction conditions. Generally, N-(tosylmethyl)ureas afford alpha-ureido nitriles, N-(tosylmethyl)-N’-cyanoguanidines transform into 4-amino-2-cyanimino-1,5-dihydro-2H-imidazoles, and N-(tosylmethyl)thioureas give complex mixtures of various imidazole derivatives. The prepared alpha-ureido nitriles are selectively converted into the corresponding alpha-ureido amides by treatment with conc. HCl at room temperature. Under basic conditions, alpha-ureido nitriles cyclize into 4-amino-1,5-dihydro-2H-imidazole-2-ones. Treatment of 4-amino-2-cyanimino-1,5-dihydro-2H-imidazoles with conc. HCl at room temperature lead to hydrolysis of both the amidine fragment and cyano group to give hydrochlorides of 2-(carbamoylimino)imidazolidin-4-ones which are easily decarbamoylated to form hydrochlorides of 2-iminoimidazolidin-4-ones. Structure of the prepared imidazoles and some mechanistic aspects of cyanide-anion amidoalkylation with N-(tosylmethyl)ureas are discussed based on DFT calculations.
