Novel P(III) bisamidite reagents as phosphorus protecting groups, nucleoside phosphoramidite intermediates, and synthetic processes for making the same are disclosed. Furthermore, oligomeric compounds are prepared through the protection of one or more internucleosidic phosphorus functionalities, preferably followed by oxidation and cleavage of the protecting groups to provide oligonucleotides. Methods for preparing oligoribonucleotides are also disclosed.
本发明揭示了Novel P(III)双酰胺试剂作为
磷保护基,核苷酸
磷酰胺中间体和制备它们的合成过程。此外,通过保护一个或多个核苷酸之间的
磷功能基,最好是随后进行氧化和去保护基,以提供寡核苷酸,制备寡聚化合物。本发明还揭示了制备寡
核糖核酸的方法。
