Herein, a novel route to atropisomeric N-aryl quinolones with low rotational barriers is demonstrated, leveraging a dual photochemical/organocatalytic approach to the required ring closure in up to 94% yield and up to >99% ee. The use of a continuous flow system allows for impurity suppression and enables rapid scale-up to a decagram scale.
在此,展示了一种具有低旋转势垒的阻转异构 N-芳基喹诺酮类化合物的新途径,利用双重光化学/有机催化方法实现所需的闭环,收率高达 94%,ee 高达 >99% 。使用连续流系统可以抑制杂质,并能够快速放大至十克规模。
