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.
