A two-step approach to a family of C1′-disubstituted C-nucleosides is described. It relies on a double aryl condensation on ribonolactone 1 to give the desired disubstituted diols 2c, 6c and 7c. The cycloetherification of these diols followed by protecting group cleavage gave high yields of C-nucleosides 2d, 6d and 7d, respectively, featuring two hydrophobic aryl groups as nucleobase surrogates.
本文介绍了一种分两步制备 C1′-二取代 C 核苷家族的方法。该方法通过核糖酸内酯 1 的双芳基缩合,得到所需的二取代二醇 2c、6c 和 7c。将这些二元醇环醚化后再进行保护基裂解,可分别得到高产率的 C 核苷 2d、6d 和 7d,它们具有两个疏水芳基作为核碱基替代物。
