A simple and efficient method for the synthesis of highly substituted spiroindoline derivatives is presented. A Fischer indolization is combined with Ugi-type reactions to explore the chemical space concerning this privileged structure. Moreover, spiropiperidine derivatives could be postmodified for the production of a small-molecule library that will be part of the Joint European Compound Library
提出了一种简单有效的合成高度取代的螺二氢吲哚衍生物的方法。Fischer 吲哚化与 Ugi 型反应相结合,以探索有关这种特殊结构的化学空间。此外,螺哌啶衍生物可以进行后修饰以生产小分子库,该库将成为欧洲铅工厂的欧洲联合化合物库的一部分。
