Abstract

The structures of previously obtained nucleosides of 5-substituted 4-chloro-1, 2,3-triazoles were refined by means of high-resolution mass spectrometry and 13C NMR spectroscopy. It is shown that fusion of 5-substituted 4-chloro,1,2,3-triazoles with tetra-0-acylribofuranoses in the presence of di(p-nitrophenyl) phosphate leads to the formation of 2-nucleosides of the corresponding triazoles. The signals of the carbon atoms in the 13C NMR spectra of the 4,5-di-substituted triazoles and their nucleosides were assigned.
