The corresponding ethyl 5-carbonylglycinates were synthesized by condensation of 4-(Boc-amino)-1,2,3-triazole-5-carboxylic acids with ethyl glycinate hydrochloride. They were intramolecularly cyclized with the selective formation of 1,4,6,7-tetrahydr

5-Amino-N-(2,2-dimethoxyethyl)-1Н-1,2,3-triazole-4-carboxamides in formic acid were subjected to intramolecular cyclization to 5-hydroxy[1,2,3]triazolo[4,5-е][1,4]diazepines, which were converted by treatment with S-nucleophiles to 5-thio-functiona
