Abstract: | By reaction of N,N-acetals of acylketenes with tosylazide there were synthesized 5-amino-4-acyl-1,2,3-triazoles substituted at the endo(N1)- or exocyclic nitrogen atom. Triazoles containing a free NH2 group were used in the synthesis of the corresponding 8-azapurines and 4-acetyl-5-benzoylamino-1,2,3-triazole afforded 2-methyl-2H,4H-1,2,3-triazolo4,5-b]pyridin-7-one.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1392–1397, June, 1990. |
