3-Isopurine nucleosides, namely 3-(ribofuranosyl)purine nucleosides, are interesting owing to their potential biological activity and as components of modified oligonucleotides. A regio- and stereocontrolled method was developed for the synthesis of β-2′-deoxy-3-isopurine nucleosides using the intramolecular glycosylation protocol. The availability of this method was shown by the first chemical synthesis
3-异嘌呤核苷,即3-(呋喃呋喃糖基)嘌呤核苷,由于其潜在的生物学活性并作为修饰的寡核苷酸的组分,因此是令人感兴趣的。开发了区域和立体控制的方法,用于使用分子内糖基化方案合成β-2'-脱氧-3-异嘌呤核苷。通过3-(2-脱氧-β - d-核呋喃呋喃糖基)黄嘌呤和异鸟嘌呤的第一化学合成显示了该方法的可用性。
