Synthesis of 3'-Azido-5'-homothymidine Analogs.

Abstract 1-(3′-azido 2′,3′,5′-trideoxy-β- D -allofuranosyl) thymine 13, and 1-(3′-azido-3′,5′-dideoxy-β- D -(glucofuranosyl) thymine 20 and its 2′- O -methyl ether 22 were synthesized starting from 1,2-O-isopropylidene-α- D -glucopyranose and from 1,2-O-isopropylidene-α- D -allofuranose, respectively.
