H-phosphonate synthesis of oligoribonucleotides containing modified bases. I. Photoactivatable derivatives of oligoribonucleotides with perfluoroarylazide groups in heterocyclic bases

H-phosphonate synthesis was proposed for oligoribonucleotides containing a bromine atom or an ethylenediamine linker at positions C5 or C8 of uridine or adenosine, respectively. Novel photoactivatable derivatives of oligoribonucleotides harboring a p-azidotetrafluorobenzoyl group attached to uridine or adenosine through the diamino linker were synthesized.

The H-phosphonate synthesis of oligoribonucleotides containing modified bases

An alternative solid phase H-phosphonate synthesis of oligoribonucleotides bearing a bromine atom or an aliphatic amino linker at position C-5 of uridine or C-8 of adenosine was proposed.
