Stereodefined oligonucleoside H‐phosphonates were synthesized on a solid support using diastereopure nucleoside 3′‐O‐oxazaphospholidine monomers. Several stereodefined backbone‐modified analogues were obtained with the oligonucleoside H‐phosphonates as precursors (see scheme; BPRO=protected nucleobase, DMTr=4,4′‐dimethoxytrityl, Th=thymin‐1‐yl, TfO−=triflate).
使用非对映体纯核苷3'- O-氧杂氮杂磷啶单体在固体支持物上合成立体定义的寡核苷H-膦酸酯。与寡核苷得到几个stereodefined骨架修饰的类似物ħ -phosphonates作为前体(参见方案;乙PRO =保护的核碱基,将DMTr = 4,4'-二甲氧基三苯甲基,TH =胸腺嘧啶-1-基,TFO - =三氟甲磺酸酯)。
