Publikováno v: Chemistry of Heterocyclic Compounds. 13:537-542

It is shown on the basis of a study of the IR spectra of indazoles, pyrazolopyridines, and pyrazolopyrazine in the solid state and of their N-deutero-substituted derivatives and hydrochlorides at room temperature and at the temperature of liquid nitr

Autor: M. N. Preobrazhenskaya, H. Dorn, I. A. Korbukh, F. F. Blanko

Publikováno v: Chemistry of Heterocyclic Compounds. 17:1102-1104

N-Glucoside analogs of the antibiotic pyrazofurine were obtained by fusion of 3-hydroxy-4-ethoxycarbonylpyrazole with tetra-O-acetyl-s-D-ribofuranose in the presence of iodine.
