, p. 747 - 756 (2019/01/23)
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-amino-4-aryl- and 3-amino-4-hetarylfurazans from β-aryl- and 4-β-hetaryl-β-oxo acid esters was developed.
