Key intermediate 6-chloro-7-deazapurine 2'-C-methyl-beta-D-ribofuranoside was prepared via a stereoselective nucleobase anion glycosylation with toluoyl protected 1,2-anhydro-2-C-methylribofuranose. The 6-chloro-7-deazapurine arabinofuranoside intermediate was obtained by epimerization from 3',5'-protected 6-chloro-7-deazapurine ribofuranoside via 2‘-hydroxyl oxidation followed by reduction. None of the prepared compounds showed any considerable cytostatic or antiviral activity.
