摘要
A facile synthesis of 4-hydroxy-3-arylthiazolidine-2-thiones through novel domino reactions of aryl isothiocyanates and 1,4-dithiane-2,5-diol under solvent-and catalyst-free microwave irradiation is reported. This highly atom efficient reaction presumably proceeds via 2-mercaptoacetaldehyde generation/thia-Michael addition/regioselective hemiaminalization domino sequence. This reaction also proceeds in good yields with aryl isocyanates affording 3-phenylthiazol-2(3H)-ones.
