new tri- and tetra-cyclic thiosemicarbazone derivatives were prepared via the condensation of morpholine, piperazine or N-(4-methoxyphenyl)piperazine with seven methyl hydrazine-carbodithioate derivatives of 5-acetyl-2-arylamino-4-methylthiazoles under microwave irradiation. All compounds were tested for their cytotoxic activity in vitro against human gastric, lung and breast cancer cell lines. The results

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
