A facile and chemoselective SnCl 2 -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.

A "one-pot" method for the synthesis of 3-alkyl-4-aminofurazans from ethyl β-alkyl-β-oxopropionates was developed. The multistep process involves hydrolysis of the ester, nitrosation at the activated methylene group, and treatment of the resulting intermediate with an alkaline solution of hydroxylamine in the presence of urea.

The kinetics of the reaction of hydroxyiminoacetone with hydroxylamine were studied by PMR spectroscopy.The formation of 3-amino-4-methylfurazan is a multistage process; the intermediate products are methylglyoxime, methylfurazan, α-hydroxyiminopropionitrile, and methylaminoglyoxime, and the side product is α-hydroxyiminopropionamide.
