technology in early phase drug discovery represents a significant demand for DNA-compatible synthetic methods for therapeutically relevant heterocycles. Herein, we report the first on-DNA synthesis of multisubstituted indoles via a cascade reaction of Sonogashira coupling and intramolecular ring closure. Further functionalization by Suzuki coupling at the third position exploits a diverse chemical space.
DNA 编码文库技术在早期药物发现中的作用日益增强,这表明对治疗相关
杂环化合物的 DNA 兼容合成方法的巨大需求。在此,我们报道了通过 Sonogashira 偶联和分子内闭环的级联反应首次在 DNA 上合成多取代
吲哚。通过铃木偶联在第三位进行的进一步功能化利用了多样化的
化学空间。该方法的高保真度还使得能够构建基于
吲哚的模拟库。
