parameters necessary for antiviral efficacy of certain purine nucleosides, several 9-beta-D-ribofuranosylpurine-6-carboxamides have been synthesized. Glycosylation of the Me3Si derivative of purine--6-carboxamide with protected ribofuranose in the presence of a Lewis acid gave the blocked nucleoside which on deprotection furnished 9-beta-D-ribofuranosyl-6-iodopurine with cyanide ion. Certain 2-amino- and 2-
