A series of purine 3'-deoxyribonucleosides bearing diverse C-substituents (alkyl, aryl, hetaryl or hydroxymethyl) in the position 6 was prepared by Pd-catalyzed cross-coupling reactions of 6-iodo-9-[2,5-bis-O-(tert-butyldimethylsilyl)-3-deoxy-β-D-ribofuranosyl]purine with the corresponding organometallics followed by deprotection by (HF)3·Et3N. None of the title 3'-deoxyribonucleoside showed any cytostatic activity or anti-HCV effect in replicon assay.
