A multicomponent one-pot process led to the formation of diversely trisubstituted 2-iminothiazolines and disubstituted 2-aminothiazoles underaqueousconditions. Starting from isocyanides, amines, 2’-bromoacetophenones, and aqueous polysulfide solution or sulfurpowder, this efficient procedure enabled the chromatography-free separation of solid products.

An efficient and practical thiocarbonyl surrogate via combination of sulfur and chloroform has been developed. A variety of thiocarbamides and oxazolidinethiones have been established, including chiral thiourea catalysts and chiral oxazolidinethione auxiliaries with high selectivity. Meanwhile, pesticides Diafenthiuron (an acaricide), ANTU (a rodenticide), and Chloromethiuron (an insecticide) were

3-dihydrothiazole derivatives, substituted in the 3-position with a beta-phenethyl moiety and the 4-position with substituted aryl functions, was synthesized as potential antimicrobial, antihypertensive and anticonvulsive agents. While no antimicrobial or significant antihypertensiveactivity was observed for the products, XII, XIII, and XXI displayed potent anticonvulsantactivity.
