STRUCTURE ASSIGNMENT OF N-PROTECTED 2-(1H-1,2,3- TRIAZOL-1-YL)-GLYCINE DERIVATIVES BY CHEMICAL AND SPECTROSCOPIC METHODS

This paper describes the assignment of the 1,4- and 1,5-regioisomer structures of N-protected 2-(1H-1,2,3-triazol-1-yl)-glycine derivatives on the basis of 1H NMR, IR and chemical pathway. A subsequent assignment of 1,4- and 1,5-regioisomer structures of biheterocyclic glycine derivatives and their phosphonic analogs were based on spectroscopic study in 1H NMR and 13C NMR.
