We report the tandem Staudinger/aza-Wittig/Ugi three-component reaction mediated synthesis of a 64-member compound library of aza-C-glycosides. The library is composed of four pyrrolidine and three piperidine scaffolds, onto which a number of functional groups is grafted to form seven sublibraries. Variation in the library is achieved by transformation of two pentoses and a hexose into the corresponding
我们报告串联 Staudinger/aza-Wittig/Ugi 三组分反应介导的 aza-C-糖苷 64 成员化合物库的合成。该文库由四个吡咯烷和三个哌啶支架组成,在其上接枝了许多官能团以形成七个子文库。通过将两种戊糖和一种己糖转化为相应的 4-叠氮戊醛和 5-叠氮己醛衍生物作为 Staudinger/aza-Wittig 过程的前体,可以实现文库的变化。通过在完全保护的 Ugi-3CR 中间体上使用不同的异氰化物以及保护和官能团操作,可以实现进一步的变化。化合物库的初步生物学评估揭示了几种低微摩尔人酸性葡糖神经酰胺酶抑制剂
