A rapid and convenient procedure has been developed for the synthesis of fully protected mono, di and trideoxyribonucleotides utilizing an aryl phosphoroditriazolide. It affords advantages over coupling strategies employing condensing reagents, such as 2,4,6-triisopropylbenzenesulfonyl tetrazolide in preparing small oligonucleotides and is relatively free of the drawbacks inherent in other approaches using bifunctional phosphorylating reagents. In particular, the synthesis of trinucleotide blocks without purification at the dimer stage is described.
已开发出一种快速便捷的方法,用于利用芳基磷酰三叠氮化物合成完全保护的单、二和三脱氧核糖核苷酸。与使用缩合试剂(如2,4,6-三异丙基苯磺酰四唑)的偶联策略相比,该方法在制备小寡核苷酸方面具有优势,并且相对没有使用双功能磷酸化试剂的其他方法所固有的缺点。特别描述了在二聚体阶段无需纯化即可合成三核苷酸片段的方法。
