ABSTRACT An elegant, mild, and straightforward strategy for the synthesis of indole derivatives have been accomplished by the biomimetic catalysis for the first time in water under neutral conditions. This supramolecular catalyst oriented methodology provides a sustainable and green protocol for the synthesis of 6H-indolo[2,3-b]quinoxalines and 3H-spiro[benzo[d]thiazole-2,3’-indolin]-2’-one by the
摘要 在中性条件下,首次通过仿生催化实现了一种优雅、温和且直接的吲哚衍生物合成策略。这种以超分子催化剂为导向的方法为合成 6H-indolo[2,3-b]quinoxalines 和 3H-spiro[benzo[d]thiazole-2,3'-indolin]-2'-one 提供了可持续的绿色方案。使用 β-环糊精 (β-CD) 作为可回收和可重复使用的超分子催化剂,使靛红衍生物与 1,2-双官能化苯反应。图形概要
