strategy to introduce phosphoramidate (PNH2) internucleosidic linkages in oligonucleoside phosphodiesters using dimer building blocks. The PNH2 function is generated under photolysis of the N-2-nitrobenzylphosphoramidate linkage (PNHR). We achieved the synthesis of N-2-nitrobenzylphosphoramidate β and α-anomeric nucleotides dimers via either phosphoramidite or H-phosphonate c chemistry. α-dimer (PNHR)
我们描述了一种新的战略,使磷酰胺(PNH 2)使用二聚体积木寡核苷磷酸二酯间键合。在N-2-硝基苄基氨基磷酸酯键(PNHR)的光解下产生P generatedNH 2功能。我们通过亚磷酰胺或H-膦酸酯化学方法实现了N-2-硝基苄基氨基磷酸酯β和α-异头核苷酸核苷酸二聚体的合成。α-二聚体(PNHR)中掺入限定位置为α-寡核苷磷酸二酯和PNH 2连杆通过UV照射中解放出来。
