palladium‐catalyzed CH oxidation of isoquinoline N‐oxides has been developed for regioselectively synthesizing substituted isoquinolines. The method represents the first example of using dialkyl sulfoxides as the alkyl sources for the construction of 1‐alkylated isoquinolines. Moreover, the regioselective halogenation of isoquinoline N‐oxides is also successful using dihalo sulfoxides as the halide sources
一种新颖的钯催化的C ^ 异喹啉h的氧化Ñ -oxides已经开发了区域选择性取代的合成异喹啉类。该方法代表了使用二烷基亚砜作为构建1-烷基化异喹啉的烷基源的第一个例子。此外,使用二卤亚砜作为卤化物源,异喹啉N-氧化物的区域选择性卤化也是成功的。
