The condensation of N-aryl thioureas with 3-bromo-acetylacetone in neutral solvent acetone not only led to 5-acetyl-4-methyl-2-(substituted anilino) thiazoles 3 but also 2-imino-3-(substituted phenyl)-4-methyl-5-acetyl-2,3- dihydrothiazoles 4. Further study found that different reaction solvents displayed an important role toward the ratio of aminothiazoles 3 and iminodihydrothiazoles 4, and the reaction scope was extended. A plausible mechanism involving solvent effect and in situ hydrobromic acid catalyzation was proposed. Some selected isomers exhibited moderate in vitro antiproliferative activity on human cervical cancer cell lines (Hela, Siha).
