The present invention is directed to the process for the preparation of 2′-deoxy-2′-halo-&bgr;-L-arabinofuranosyl nucleosides, and in particular, 2′-deoxy-2′-fluoro-&bgr;-L-arabinofuranosyl thymine (L-FMAU), from L-arabinose, which is commercially available and less expensive than L-ribose or L-xylose, in ten steps. All of the reagents and starting materials are inexpensive and no special equipment is required to carry out the reactions.

Unnatural nucleoside analogues are valuable research and clinical tools as antiproliferative, antibacterial or antiviral agents. In this context, clevudine (L-FMAU), a reverse transcriptase inhibitor, is currently used for the treatment of the hepatitis B virus. Herein, we describe a new strategy for the preparation of clevudine. Starting from 2-deoxy-2-fluoro-D-galactopyranose, we developed the shortest
