A variety of α-bromoketones undergoes smooth condensation with thiourea/ thioamide compounds to afford the corresponding substituted thiazole derivatives in excellent yields. The condensation reactions were carried out in a recyclable reaction medium glycerin without using any catalyst. All the reactions were completed within 2 hours of reaction time at room temperature.
