Abstract: Novel congeners of the antiretroviral compound 2', 3'-dideoxyadenosine (ddA) have been synthesized through metal-mediated and photochemical conversions as the key steps. These compounds are inherently more stable than ddA with respect to both glycosidic bond cleavage and deamination by adenosine deaminase.
