Solid‐Phase Synthesis of 2′‐Deoxy‐2′‐fluoro‐ β‐ D ‐Oligoarabinonucleotides (2′F‐ANA) and Their Phosphorothioate Derivatives

This unit describes the chemical synthesis of 2'-deoxy-2'-fluoro-b-D-oligoarabinonucleotides (2'F-ANA), both with phosphodiester and phosphorothioate linkages. The protocols described herein include araF phosphoramidite preparation, assembly on DNA synthesizers, and final deprotection and purification of oligonucleotides.
