A facile and chemoselective SnCl2-mediated mild reduction of regioisomeric 3- and 4-nitrofuroxans for the synthesis of aminofurazans and aminofuroxans in good yields is developed. Reduction of 4-nitrofuroxans results in the selective formation of 4-aminofuroxans, while analogous reduction of 3-nitrofuroxans affords 3-aminofurazans as a result of simultaneous reduction of the nitro group and exocyclic N–O bond.
