Synthesis of D- and L-apio nucleoside analogues with 2'-hydroxyl group as potential anti-HIV agents.
The present work describes the asymmetric synthesis of D- and L-apio-2',3'-dideoxynucleoside analogues, 4 and 5 with 2'-hydroxyl group via a common intermediate 9, starting from D-galactose. Stereoselective dihydroxylation and deoxygenation through radical inversion were successfully employed to synthesize the key intermediate 12 with D-apio structure, while stereoselecetive hydroboration-oxidation was used for the synthesis of another key intermediate 18 with L-apio structure.
