Recently, we have developed a novel reaction for the transformation of boranophosphate diesters to the corresponding H-phosphonate diesters in the presence of trityl cation under acidic conditions. In this study, DNA and backbone-modified DNA analogs were synthesized in good yields upon applying this reaction. We report the transformation of boranophosphate DNAs, fully protected with 2-azidomethylbenzoyl groups, to various backbone-modified DNA analogs via the H-phosphonate intermediates in solution and on a solid support.
