article we revisit the synthetic methodology for oligonucleotides interconnected via pyrophosphates that relies on reactivity of phosphorodiamidous anhydrides. We have found this method, previously published by Ahmadibeni and Parang (2007), to be irreproducible in our hands. We synthesized successfully three pyrophosphate interconnected thymidine oligonucleotides, identical to the claimed structures in their
在本文中,我们重新审视了通过焦磷酸盐互连的寡核苷酸的合成方法,该方法依赖于磷酸二酰胺酐的反应性。我们发现这种由 Ahmadibeni 和 Parang (2007) 先前发表的方法在我们手中是不可复制的。我们通过我们独立开发的方法成功合成了三个焦磷酸互连的胸苷寡核苷酸,与他们文章中要求保护的结构相同。对新合成产品的光谱数据的评估使人们对 Ahmadibeni-Parang 方法的可行性产生了怀疑。因此,我们相信在这里报告了通过焦磷酸键互连的 DNA 寡聚体的首次成功合成。
