[EN] METHODS AND REAGENTS FOR SYNTHESIZING NUCLEOSIDES AND ANALOGUES THEREOF [FR] PROCÉDÉS ET RÉACTIFS POUR SYNTHÉTISER DES NUCLÉOSIDES ET DES ANALOGUES DE CEUX-CI
Novel substituted 1,2,3-triazole nucleosides such as 4-R'-2-.beta.-D-ribofuranosyl-1,2,3-triazole wherein R' is a nitro, carboxylic acid ester, cyano, carboxamide or thiocarboxamide group are prepared by a procedure entailing fusion of an appropriately substituted 1,2,3-triazole with a tetra-0-acyl blocked ribofuranose. The resulting compounds exhibit significant antimicrobial activity in in vitro testing or are useful in preparing compounds which exhibit such activity.

In the presence of an arylboronic acid catalyst, azole-type heterocycles, including purines, tetrazoles, triazoles, indazoles, and benzo-fused congeners, undergo regio- and stereoselective N-glycosylations with furanosyl and pyranosyl trichloroacetimidate donors. The protocol, which does not require stoichiometric activators, specialized leaving groups, or drying agents, provides access to nucleoside
