A convenient method for the synthesis of thiazoles by treatment of alpha-bromoketones with thioamides (Hantzsch synthesis) in the absence of catalysts under microwave irradiation has been developed. The products were formed rapidly in excellent yields. An efficiency comparison of time, yield, and effort clearly proved the microwave technique to be superior. The structures of the newly synthesized compounds were characterized by spectroscopic data and elemental analyses. The synthesized compounds were tested for their biological activity. Depending on the substituents, some of the thiazoles exhibit very good antibacterial or antifungal activity.
