Stereoselective synthesis of β-L-2',3'- dideoxy- and L-2',3'- didehydro-2',3'-dideoxy purine nucleosides

β-L-2',3'-Dideoxy- and L-2',Y-didehydro-2',Y-dideoxy purine nucleosides have been synthesized via a highly stereoselective method of glycosylation by the condensation of L-2-(phenylselenyl)-2,3-dideoxyribose derivative with silylated heterocyclic base.

Anti-human immunodeficiency and anti-hepatitis B virus activities of β-L-2',3'-dideoxy purine nucleosides

β-L-2',3'-Dideoxyadenosine, β-L-2',3'-didehydro-2',3'-dideoxyadenosine and related compounds were synthesized in a stereoselective manner. These compounds were tested in vitro against HBV in 2.2.15 cell line and against HIV-1 in PBM and CEM cells. It was found that β-L-2',3'-didehydro-2',3'-dideoxyadenosine (7) exhibited significant anti-HIV (EC50 0.38 μM in PBM cells) and anti-HBV activity (EC50 1.2 μM).
