Perfluoroalkanesulfonyl fluorides are effective dehydroxy-fluorination agents for the hydroxyl group at the sugar moiety of nucleoside derivatives and give the corresponding fluorinated nucleosides in good yield with an inversion of configuration in a sin

A novel synthesis for preparing 9-(3-O-benzyl-5-O-tetrahydropyranyl-β- D-arabinofuranosyl)adenine (6) has been developed which does not require sub zero temperatures or exotic reagents. A key step in this synthesis is the selective protection of the 3′-OH of ara-A with a benzyl group. The 5′-OH is then selectively protected with DHP to yield 6, a potentially useful intermediate. A synthesis of 9-(2,3-dideoxy-2-fluoro-β-D-threo- pentofuranosyl)adenine (1, FddA), an anti-viral compound, is given to illustrate the utility of this new approach.

Two industrial synthetic approaches to Lodenosine (1, FddA, 9-(2,3-dideoxy-2-fluoro-β-D-threo-pentofuranosyl) adenine) via a purine riboside or a purine 3′-deoxyriboside are described. Several novel applications of deoxygenation and fluorination methods are compared considering reaction yields, economy, safety and environmental concerns.
