Herein, the atroposelective construction of isoquinolinones bearing a C–N chiral axis has been successfully developed via a Co-catalyzed C–H bond activation and annulation process. This conversion can be effectively carried out in an environmentally friendly oxygen atmosphere to generate the target C–N axially chiral frameworks with excellent reactivities and enantioselectivities (up to >99% ee) in
在此,通过共催化的C-H键活化和成环过程,成功开发了带有C-N手性轴的异喹啉酮的天体选择性结构。这种转化可以在环保的氧气气氛中有效地进行,在没有任何添加剂的情况下生成具有优异反应活性和对映选择性(高达 >99% ee)的目标 C-N 轴向手性框架。此外,目前的方案已被证明是在电化学条件下用于钴/Salox催化的C-N轴向结构制造的替代方法,并且该策略允许在温和的反应条件下高效且原子经济地合成各种轴向手性异喹啉酮。
