  摘要：

  A new and practical synthesis of a fluorinated analogue of 2',3'-dideoxycytidine (ddC), 1-(2,3-dideoxy-2-fluoro-beta-D-threo-pentofuranosyl)cytosine (F-ddC), is described. The key feature in the synthesis is the use of the selectively protected 2,4,5-trihydroxypentanoic acid derivative 15 as a chiral pool synthon.

  anti-HIV active 9-(2,3-dideoxy-2-fluoro-β-D-threo-pentofuranosyl)adenine (1, FddA) and 1-(2,3-dideoxy-2-fluoro-β-D-threo-pentofuranosyl)cytosine (2, FddC) was prepared via the diastereoselective fluorination of the chiral imide enolate obtained from 8 with N-fluorobenzenesulfonimide. The overall yield of 10 from the readily available 1,2:5,6-di-O-isopropylidene-D-mannitol was 25% (de 93%).

  Methods for forming 2-bromo, 2-fluoro ribofuranose intermediates and 2-chloro, 2- fluoro ribofuranose intermediates for use in preparing antiviral nucleosides are disclosed. Methods for forming nucleosides, and nucleoside prodrugs, using the intermediates, are also disclosed. The methods all produce intermediates, and the resulting nucleosides and prodrugs thereof, wherein the chirality of the carbon at the 2-position is controlled. In some embodiments, the chemistry involves using chiral auxiliaries, such as (R)-2,2-dimethyl-l,3- dioxolane-4-carbaldehyde, and in other embodiments, the chemistry involves using chiral starting materials, such as D-xylose.
