Am. Churakov et al., SYNTHESIS OF 4H-[1,2,3]TRIAZOLO[4,5-C][1,2,5]OXADIAZOLE 5-OXIDE AND ITS N-ALKYL AND O-ALKYL DERIVATIVES, Tetrahedron letters, 37(47), 1996, pp. 8577-8580
The synthetic route to the fused 1,2,3-triazole 2-oxide systems via in
tramolecular cyclization of N-nitroso and azido groups is described. T
he title compounds are characterized by H-1, C-13, N-14, N-15 and O-17
NMR spectroscopy. Copyright (C) 1996 Elsevier Science Ltd
