2'-F-ANA-A (Bz) CE Phosphoramidite is a 2'-deoxy-2'-fluoro-arabinonucleoside (2'F-ANA) building block: 5'-O-(4,4'-dimethoxytrityl)-N6-benzoyl-2'-deoxy-2'-fluoro-arabinoadenosine 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. CH65067 is identified by CAS 329187-86-2, molecular formula C47H51FN7O7P, molecular weight 875.9, PubChem CID 124587489, and InChIKey VCCMVPDSLHFCBB-SAHKUVNLSA-N.
In 2'F-ANA the sugar is arabino-configured at C2'; the fluorine sits on the face opposite that of a 2'-ribo substituent, which distinguishes 2'F-ANA from 2'-F-RNA. The cited 2'F-ANA literature discusses 2'F-ANA/RNA duplex behavior with RNase H. Because C2' carries fluorine rather than a hydroxyl, no 2'-protecting group is needed; the monomer couples through a standard 3'-phosphoramidite (3'→5' linkages), the 5'-DMT is removed each cycle, and the N6-benzoyl base group is removed at final deprotection.

Contexte d’application
- Arabino 2'-fluoro sugar: the fluorine at C2' is in the arabino configuration (distinct from ribo 2'-F-RNA), the defining structural feature of 2'F-ANA.
- RNase H literature context: the cited 2'F-ANA literature discusses 2'F-ANA/RNA duplex behavior with RNase H.
- 3'→5' coupling monomer: the 3'-phosphoramidite couples to form 3'→5' linkages; the 5'-DMT is removed each cycle and the N6-benzoyl base group is removed at final deprotection. No 2'-protecting group is needed (C2' bears fluorine, not a hydroxyl).

Questions fréquentes
How does 2'F-ANA differ from 2'-F-RNA?
Both carry a fluorine at C2', but the configuration differs: 2'F-ANA is arabino (fluorine on the opposite face), whereas 2'-F-RNA is ribo. This arabino configuration is the defining structural feature of 2'F-ANA.
Are 2'F-ANA/RNA duplexes cleaved by RNase H?
The cited 2'F-ANA literature reports RNase H substrate behavior for 2'F-ANA/RNA duplexes. This page uses that point only to explain the nucleic-acid chemistry context for the 2'F-ANA class.
