The O,S-dimethylphosphorochloridate reacts with 5′-O-monomethoxytritylthymidine in pyridine giving nucleoside-3′-thiolophosphodiester in high yields; in acetonitrile and in the presence of 1-methylimidazole, this reaction leads to the nucleoside-3′-phosphotriester without formation of diester . From the latter, the Tp and TpT have been prepared.
O,S-二甲基氯代磷酸酯与吡啶中的5'-O-单甲氧基三苯甲基胸苷反应,以高收率得到核苷-3'-硫代磷酸二酯;在乙腈中和在1-甲基咪唑存在下,该反应可生成核苷3'-磷酸三酯,而不会形成二酯。由后者制备了Tp和TpT。
