Summary for Patent: RE29835
Title: 1,2,4-Triazole nucleosides
Abstract:As antiviral agents and intermediates therefor, 3-substituted 1-(.beta.-D-glycosyl)-1,2,4-triazoles, O-acylated analogs thereof, and 5'- and 3',5'-cyclic phosphates of the triazole nucleosides, "glycosyl" being .[.a pentofuranosyl moiety, preferably one whose 2'-oxygen is trans to the triazole aglycon, e.g., xylofuranosyl,.]. ribofuranosyl, .[.2-0-methylribofuranosyl, etc.,.]. the triazole aglycon being 3-substituted with cyano, methylcarboxylate, carboxamidoxime, carboxamido-, thiocarboxamido, or carboxamidine. Preparation of these nucleosides is by silylation of the substituted triazole followed by glycosylation with the appropriate blocked glycosyl halide. Alternatively, acid-catalyzed fusion of the requisite 1,2,4-triazole with an O-acylated pentofuranose yields the nucleosides.
