Abstract

Sodium naphthalenide effects removal of 2′-, 3′-, or 5′-O-tosyl groups from the sugar, and 2-, 6-, or 8-halogens from purine nucleosides. An improved tosyl protection strategy was developed for the synthesis of 9-(3-deoxy-3-fluoro-β-D-xylofuranosyl) adenine from 2′, 5′- di-O-tosyladenosine.
