A rapid and effective method of an automatic oligoribonucleotidesynthesis alternative to the phosphoroamidite one was developed based on the phosphotriester approach of internucleotide bond formation under intramolecular O-nucleophilic catalysis and the use of an azidomethyl group for protection of a nucleotide 2'-hydroxyl function.

2-(azidomethyl)benzoyl as 2′-OH protecting groups are reported for preparation of oligoribonucleotides by the phosphotriester solid-phase method using O-nucleophilic intramolecular catalysis. The procedures for the synthesis of the corresponding monomer synthons were developed and the usefulness of the application of 2′-O-azidomethyl and 2′-O-2-(azidomethyl)benzoyl groups was examined in the synthesis of different
