    A new, simple, and general method for the synthesis of 6-R-7H-tetrazolo[5,1-b][1,3,4]thiadiazines (R = Ar, Het, Alk) has been developed. The described method is based on the one-pot condensation of α-haloketones with thiocarbohydrazide, nitrosation of the formed hydrazinylthiadiazine using NaNO2/HCl, and intramolecular cyclization of the nitrosation product via azide-tetrazole tautomerism.

    The effective and regioselective synthesis of new (2-hydrazinylthiazol-4-yl)furoxan hydrobromides based on the condensation of (bromoacetyl)furoxans with thiosemicarbazide has been developed. The cytotoxic activity of their derivatives (with hydrazone, 4-thiazolo[2.3-c][1,2,4]triazole or pyrrole moieties) against two human cancer cell lines (A549, HCT116) was tested and several structures revealed moderate cytotoxic activity.
