A concise synthesis of anti-viral agent F-ddA, starting from (S)-dihydro-5-(hydroxymethyl)-2(3H)-furanone

Anti-HIV agent β-F-ddA (1) has been synthesized starting from readily available non-sugar, (S)-(+)-Dihydro-5-(hydroxymethyl)-2-(3H)-furanone (4). A highly syn-stereoselective fluorination of the hydroxy lactone 2 generates the key intermediate fluorolactone 5 in a short and concise synthetic sequence. Reduction of 5 followed by bromination generates the aglycon which is glycosylated to generate F-ddA by amination and deprotection. Steric bulk of the 5-protecting group has minimal effect on the steric course of glycosylation.

2'-Fluoro-4'-thio-2',3'-unsaturated nucleosides: anti-HIV activity, resistance profile, and molecular modeling studies.

Both D- and L-2'-fluoro-4'-thio-2',3'-unsaturated nucleosides were synthesized and their anti-HIV activity against the drug sensitive virus and lamivudine-resistant mutant (M184V) were evaluated. In vitro antiviral evaluation indicated that the L-isomers

Stereoselective synthesis and antiviral activity of d-2′,3′-didehydro-2′,3′-dideoxy-2′-fluoro-4 ′-thionucleosides

As 2′,3′-didehydro-2′,3′-dideoxy-2′ -fluoronucleosides have exhibited interesting antiviral effects against HIV-1 as well as HBV, it is of interest to synthesize the isosterically substituted 4′-thionucleosides in which 4′-oxygen is replaced by a sulfur a
