Tris(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite was used as a phosphonylating reagent for the preparation of nucleoside 3′-H-phosphonate units. The use of a new coupling reagent, 1,3-dimethyl-2-chloro-imidazolinium chloride (DMCI) for the internucleotidic H-phosphonate bond formation via the H-phosphonate approach is also discussed in detail.
使用三(1,1,1,3,3,3-六氟-2-丙基)亚磷酸酯作为膦酰化试剂来制备核苷3'-H-膦酸酯单元。还详细讨论了使用新型偶联剂1,3-二甲基-2-氯-咪唑啉鎓氯化物(DMCI)通过H-膦酸酯方法形成核苷酸间H-膦酸酯键的方法。
