Regioselective protection of primary hydroxyl group in nucleoside and carbohydrate analogs was accomplished using dimethoxytrityl alcohol (DMTr-OH) or dimethylpixyl alcohol (DMPx-OH) in presence of copper(II)nitrate as a Lewis acid catalyst. Excellent selectivity was observed for the protection of primary hydroxyl group over secondary while glycosidic bond remain unaffected. Utility of this methodology was further exemplified via DMTr- and DMPx-protection of alipahtic acyclic and cyclic diols.

Stereochemically-pure 2′-O-(2-methoxyethyl)-phosphorothioate (PS-MOE) oligonucleotides were synthesized from new chiral oxazaphospholidine-containing nucleosides. Thermal stability studies showed that the incorporation of Rp-PS linkages increased RNA-binding affinity. In cells, a full Rp-PS-MOE splice-switching oligonucleotide targeting part of the ferrochelatase gene was more potent than its Sp-PS counterpart, but of similar potency to the stereorandom PS-parent sequence.
