Abstract

N-(2-Aryl-1-chloro-2-oxoethyl) carboxamides react under mild conditions with thiourea, N-alkyl-and N-arylthioureas, and various N,N′-disubstituted thioureas, following the Hantzsch reaction scheme. The reactions are selective, and the resulting 2,5-diamino-1,3-thiazole derivatives undergo recyclization acid followed by hydrolysis to give substituted 2-thiohydantoins on heating with hydrochloric acid in ethanol.
