A simple method for the preparation of fully protected 2′-deoxynucleoside-3′-phosphates is described. The main step, phosphorylation of partially protected deoxynucleosides, is performed with the monofunctional reagent p-chlorophenyl (2-cyanoethyl) phosphochloridate3) (2) in dioxane. This reagent is quickly prepared from readily accessible p-chlorophenyl phosphodichloridate by reaction with 3-hydroxypropionitrile
描述了一种制备完全保护的2'-脱氧核苷-3'-磷酸盐的简单方法。主要步骤是部分保护的脱氧核苷磷酸化,是通过在二恶烷中的单官能试剂对氯苯基(2-氰基乙基)磷酰氯3)(2)进行的。通过与3-羟基丙腈和三乙胺在二恶烷或乙醚中反应,由易于获得的对氯苯基二氯磷酸酯快速制备该试剂。粗试剂直接用于磷酸化。层析后,分离得到保护的脱氧核苷-3'-磷酸盐,产率为80-87%。此处描述的方法已进行了详细的优化,它代表了已发布方法的一种简单替代方法。
