Phosphorylation of the 5'-O-monomethoxytrityl-2'-deoxyribonucleosides by means of aryl phosphoranilidochloridates gives the diastereoisomers of 5'-O-monomethoxytrityl-2'-deoxyribonucleoside 3'-aryl phosphoranilidates. Their separation can be performed by means of chromatographic techniques. They can be further converted to the 2'-deoxyribonucleoside cyclic 3'-5' phosphoranilidates, which are intermediates
5'-O-单甲氧基三苯甲基-2'-脱氧核糖核苷的磷酸化借助于芳基磷酰二氯氯酸酯得到5'-O-单甲氧基三苯甲基-2'-脱氧核糖核苷3'-芳基磷酸苯二酸酯的非对映异构体。它们的分离可以通过色谱技术来进行。它们可以进一步转化为2'-脱氧核糖核苷环状的3'-5'磷酸苯胺酸酯,它们是在磷处具有已知绝对构型的2'-脱氧核糖核苷环状(3'-5')硫代磷酸酯的立体有择合成的中间体。
