Abstract Depending on the reaction conditions, 2-amino-1,3,4-thiadiazine and 2-hydrazinothiazole derivatives were obtained by cyclization of thiosemicarbazide with ethyl bromopyruvate in concentrated hydrochloric acid. The rearrangements of 5-carbonyl-substituted 2-amino-1,3,4-thiadiazines to thiazole derivatives in an acidic medium were studied.
