Catalytic cerium chloride was found to activate 2-iodoxybenzoic acid (IBX) for the oxidative dehydrogenation of tetrahydroisoquinolines, tetrahydro-β-carbolines, and thiazolidines to their dehydrogenated and aromatic forms at room temperature in moderate to excellent yields. The robustness of the protocol was demonstrated by scaling up the reactions to multigram quantities.
发现催化氯化铈活化 2-碘氧基苯甲酸 (IBX),用于在室温下将四氢异喹啉、四氢-β-咔啉和噻唑烷氧化脱氢为其脱氢和芳族形式,产率中等至极好。该协议的稳健性通过将反应放大到数克数量来证明。
