摘要:A novel universal linker (UnyLinker) molecule which has a conformationally rigid and chemically stable bridge head ring oxygen atom carrying a conventional
4,4′-dimethoxytrityl (DMT) and succinyl groups locked in a syn orientation has been developed to carry out oligonucleotide synthesis efficiently and smoothly. The geometry of the vicinal syn oxygen functionalized group allows fast and clean cleavage under standard aqueous ammonia deprotection conditions to afford high-quality oligonucleotides. No ba modification is obrved, bad on the ion-pair HPLC−UV−MS (IP-HPLC−UV−MS) method with detection limit of <0.1%. A class of impurities formed by branching from the exocyclic amino group of nucleosides loaded onto a solid support has been eliminated by the u of this method.
