设计了一种新的香豆素与未活化的简单芳烃通过钯催化的双重C-H官能化反应进行区域选择性α-芳基化的方法。该方法提供了一种有吸引力的新方法来合成各种各样的3-芳基香豆素从容易获得的起始原料。
A new regioselective α-arylation of coumarins with unactivated simple arenes via a palladium-catalyzed twofold C-H functionalization is devised. This method offers an attractive new approach to synthesis of a wide variety of 3-arylcoumarins from readily accessible starting materials.
