An efficient and simple way for synthesis of thiohydantoins is reported. In the absence of any additional catalysts, a series of thiohydantoins were synthesized with amino esters and isothiocyanates in aqueous medium under microwave irradiation. Excellent isolated yields (up to 98 %) were obtained under mild conditions.
