The synthesis of 9-(2,3-dideoxy-2-fluoro-L-glycero-pent-2-eno- furanosyl)adenine and-hypoxanthine has been accomplished by direct condensation of silylated 6-chloropurine with key intermediates 8, which were prepared starting from 2,3-0-isopropylidene-L-glyceraldehyde. The synthesized nucleosides were evaluated against HIV-1 in vitro in primary human lymphocytes (PMB cells). It was found that β-L-Fd4A 12 exhibited moderately potent anti-HIV activity (EC50 1.5 μM).

2′-Fluoro-nucleoside compounds are disclosed which are useful in the treatment of hepatitis B infection, hepatitis C infection, HIV and abnormal cellular proliferation, including tumors and cancer. The compounds have the general formulae: wherein Base is a purine or pyrimidine base;R1 is OH, H, OR3, N3, CN, halogen, CF3, lower alkyl, amino, loweralkylamino, di(lower)alkylamino, or alkoxy;R2 is H, phosphate, or a stabilized phosphate prodrug; acyl, or other pharmaceutically acceptable leaving benzyl, a lipid, an amino acid, peptide, or cholesterol; andR3 is acyl, alkyl, phosphate, or other pharmaceutically acceptable leaving group; or a pharmaceutically acceptable salt thereof.
