A general procedure to obtain the 3'-aminoxylonucleosides 13a,b and 17a,b is presented. The synthetic scheme is based on the 5' directed intramolecular nucleophilic substitution at the 3'-activated position of the nucleoside. The approach of the incoming group to this position takes place regio- and stereoselectively from the most hindered face of the nucleoside. The methodology presented is applicable
提出了获得3'-氨基木糖核苷13a,b和17a,b的一般方法。合成方案基于在核苷的3'活化位置的5'定向分子内亲核取代。进入的基团到达该位置的途径是从核苷的最受阻表面区域性和立体选择性地发生的。提出的方法学适用于核糖核苷和2'-脱氧核糖核苷,无论它们的碱基是否已硝化。
