                                    Purine 2'-deoxynucleosides bearing an ethynyl or a cyano group at C-4' of the sugar moiety were synthesized from the corresponding 2'-deoxynucleosides. These compounds exhibited very potent anti-HIV activity, and remained active against drug resistant HIV strains.
