The electrochemical three‐componentassembly of isoquinolines has been accomplished by ruthenaelectro‐catalyzed C−H/N−H functionalization. The robustness of the electrocatalysis was reflected by an ample substrate scope, an efficient electrooxidation, and an operationally friendly procedure. The isolation of key intermediates and detailed mechanistic studies, including unprecedented cyclovoltammetric
异喹啉的电化学三组分组装已通过钌电子催化的CH / NH官能团完成。电催化的坚固性通过足够的底物范围,有效的电氧化作用和操作友好的程序得以体现。关键中间体的分离和详细的机理研究,包括对七元钌循环的前所未有的循环伏安分析,为不寻常的钌(II / III / I)机制提供了支持。
Synthesis of Isoquinolines from α-Aryl Vinyl Azides and Internal Alkynes by Rh-Cu Bimetallic Cooperation
Catalysts in a relay: A synthetic method for delivering highly substituted isoquinolines has been developed (see scheme; Cp*=C5Me5, DMF=N,N‐dimethylformamide, TEMPO=2,2,6,6‐tetramethylpiperidine‐1‐oxyl). A preliminary mechanistic study showed that the rhodium and copper cooperate synergistically in the multistep sequence.
继电器中的催化剂:已开发出一种用于合成高度取代的异喹啉的合成方法(参见方案; Cp * = C 5 Me 5,DMF = N,N-二甲基甲酰胺,TEMPO = 2,2,6,6-四甲基哌啶-1-氧基)。初步的机理研究表明,铑和铜在多步骤序列中协同协同作用。
