Functionalized 4,4‘-bisquinolones can be efficiently synthesized by microwave-assisted palladium(0)-catalyzed one-pot borylation/Suzuki cross-coupling reactions or via nickel(0)-mediated homocouplings of 4-chloroquinolin-2(1H)-one precursors. Both methods are also applicable to other types of symmetrical biaryls.
可以通过微波辅助钯(0)催化的一锅硼化/ Suzuki交叉偶联反应或通过镍(0)介导的4-氯喹啉2(1 H)介导的有效偶联来有效合成功能化的4,4'-双喹啉酮。一前体。两种方法也适用于其他类型的对称联芳基。
