Abstract

The cyclization of N-methylquinoxalinium iodide with ammonium salts of N-alkyl-dithiocarbamic acids in DMSO leads to 4-methyl-2,3,3a,4,9,9a-hexahydrothiazolo-[4,5-b]quinoxalines, whereas regioisomeric cycloadducts with a reversed orientation of the thiazole ring are formed in ethanol in the presence of diethylamine.
