2'-Amino-2'-deoxynucleosides and oligonucleotides containing them have proven highly effective for an array of biochemical applications. The guanosine analogue and its phosphoramidite derivatives have been accessed previously from 2'-amino-2'-deoxyuridine by transglycosylation, but with limited overall efficiency and convenience. Using simple modifications of known reaction types, we have developed
2'-氨基-2'-脱氧核苷和包含它们的寡核苷酸已被证明对一系列生化应用非常有效。鸟苷类似物及其亚磷酰胺衍生物先前已经通过转糖基化从2'-氨基-2'-脱氧尿苷中获得,但是总体效率和便利性有限。使用已知反应类型的简单修饰,我们已经开发了有用的方案,与以前报道的相比,具有更大的便利性,更少的步骤和更高的产率来获得2'-氨基-2'-脱氧鸟苷及其两个亚磷酰胺衍生物。这些亚磷酰胺为将2'-氨基-2'-脱氧鸟苷掺入寡核苷酸中提供了有效的合成子。
