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.
小说代替了1,2,3-三唑核苷,例如4-R'-2-.beta.-D-核糖呋喃基-1,2,3-三唑,其中R'是硝基,羧酸酯,氰基,羧酰胺或硫代羧酰胺基团。该方法涉及将适当取代的1,2,3-三唑与四个0-酰基阻断的核糖呋喃酮熔合。所得化合物在体外测试中表现出显著的抗微生物活性,或者用于制备表现出这种活性的化合物。
