A straightforward and inexpensive synthesis of arabinonucleoside H-phosphonates has been developed. Arabinonucleosides were synthesised from protected ribonucleosides via 2′-keto derivatives. Reaction conditions have been optimised for compounds bearing labile N-protections. Further protecting group manipulation and phosphonylation gave the required H-phosphonate monomers.
