WebSep 4, 2024 · Oligonucleotides containing phosphorothioate (PS) linkages have recently demonstrated significant clinical utility. PS oligonucleotides are manufactured via a solid-phase chain elongation process in which a four-reaction cycle consisting of detritylation, coupling, sulfurization, and failure sequence capping with Ac 2 O is repeated. WebApr 12, 2024 · Synthesizing PS/PO chimeric oligodeoxyribonucleotides in a stereoselective manner uses standard phosphoramidite and oxazaphospholidine monomers to construct phosphate and phosphorothioate linkages, respectively . One can expect that substituting a boronation reaction for sulfurization would simply provide a boranophosphate.
