Wang, Huai-Wei;Wu, Jia-Xue;Li, Da-Cheng;Qiao, Yu-Han;Yao, Qing-Xia;Sun, Wen-Can;Dou, Jian-Min research published 《 The synthesis of aryl-heteroaryl derivatives via the RhIII-catalyzed heteroarylation of arenes and heteroaromatic boronates》, the research content is summarized as follows. An efficient RhIII-catalyzed strategy for constructing aryl-heteroaryl derivatives with removable ketoxime ether auxiliaries via direct C-H heteroarylation based on arenes and heteroaromatic boronates has been disclosed. This protocol could tolerate various pyridine, pyrimidine, pyrazole, thiophene, and furan heteroaromatic boronates well, providing the desired products with high reactivities and excellent regioselectivity. The easy synthetic accessibility may offer potential for application in the synthesis of heterocyclic drug mols. containing aryl-heteroaryl motifs.
