4′-dimethoxytrityl)-2′-deoxyribonucleoside 3′-H-phosphonates 1 (B=4, 5, 6 and 7) into their partially-protected nucleoside precursors 3 (B=4, 5, 6 and 7, respectively) in good isolated yields is described. The procedure used is also suitable for the dephosphonylation of protected oligonucleotide H-phosphonate blocks.
四个5'- O-(4,4'-二甲氧基三苯甲基)-2'-脱氧核糖核苷3'- H-膦酸酯1(B = 4,5,6和7)转化为其部分保护的核苷前体3(B = 4,5,6和7在良好分离收率分别)进行说明。所用的方法也适用于保护的寡核苷酸H-膦酸酯嵌段的去膦酰基化。
