A serendipitous five-step cascade of rhodium vinylcarbenoids with aminochalcones enables a unique synthetic approach to highly functionalized tri- and tetra-cyclic quinolines. The cascade reaction begins with the insertion of aminochalcone nitrogen into rhodium vinylcarbenoids followed by intramolecular aldol cyclization to provide a substituted indoline intermediate that undergoes an oxy-Cope rearrangement

A Cu(II)-catalyzed dominoprocess involving the carbene N–H insertion, intramolecular aldol-type trapping and unprecedented ring-expansion of oxindole core through C3-selective 1,2-carbonyl migration is described for the synthesis of indolo[3,2-c]quinolinones. This tetracyclic core, having an all-carbon quaternary center, was efficiently synthesized in high yields from amines and 3-diazo-oxindoles
描述了吲哚合成的Cu(II)催化的多米诺过程,该过程涉及卡宾N–H插入,分子内醛醇型捕获和通过C3选择性1,2-羰基迁移引起的羟吲哚核的空前扩环[3, 2- c ]喹啉酮。该四环核具有全碳的季中心,可以高效率地由胺和3-重氮-氧吲哚合成。机理研究表明,该反应是通过逐步途径进行的,并且路易斯酸铜与原位形成的TfOH痕迹的隐含布朗斯台德酸度之间具有协同催化作用。

the catalyst deactivates by strong adsorption of the basic quinolinone product. Product desorption has been controlled by optimizing catalyst pore structure and surface composition, together with a proper selection of solvent and reaction temperature. Process intensification for the synthesis of aryl‐2,3‐4(1 H)‐quinolinones of pharmaceutical interest has been achieved by preparing catalysts that allow
