  摘要：

  The synthesis of purine nucleosides capable of making the guanidinium linkage is described for the first time starting from the corresponding 2'-deoxynucleosides. The positively charged mixed base DNG oligomer containing guanine was synthesized on solid-phase using CPG as support from 3' to 5' direction using the precursor building block nucleosides.

  rearrangement gave protected 9‐(2‐deoxy‐threo‐pentofuranosyl)guanines ( 10 , 12 and 16 ). This rearrangement was accomplished in high yield with a high degree of stereoselectivity using lithium triisobutylborohydride (l‐Selectride®). Compounds 10 , 12 and 16 were transformed into 3′‐O‐mesylates ( 18 and 21 ), which can be used for 3′‐substitution. The 3′‐azido nucleosides were obtained by treatment of 18 and

  All four 2',3'-dideoxy-3'-thio-nucleosides (ddtNTPs) function as substrates for the Y410F mutant of Deep Vent (exo-) DNA polymerase. Not only are the ddtNTPs incorporated to form the N + 1 product, but further elongations are observed in which the key step is attack of the 3'-thiol on the 5'-triphosphate. Although other polymerases are likely to differ in their use of the ddtNTPs, there does not appear

  所有四个2'，3'-dideoxy-3'-thio-nucleosides（ddtNTPs）充当Deep Vent（exo-）DNA聚合酶Y410F突变体的底物。不仅掺入了ddtNTP以形成N + 1产物，而且还观察到了进一步的延伸，其中的关键步骤是3'-硫醇对5'-三磷酸的侵蚀。尽管其他聚合酶在ddtNTPs的使用上可能会有所不同，但似乎没有根本禁止在磷酸酐亲电试剂上使用硫醇亲核试剂的方法。描述了四个ddtNTP（C，T，A，G）的合成。[结构：见文字]
