The reactions proceed efficiently when AgOTf is used as an anion exchange catalyst with a 20 mol % loading at 80 °C. Computational studies were performed to investigate the reaction mechanism, and the findings support the role of the −TMS group in reducing the reaction barrier of the key cyclization step.EnglishChemical reactionsAnionsAcylsCyclization CationsAza-Nazarov cyclization reactions via anion exchange catalysisArticle10.1021/acs.orglett.8b03886
