Краткое описание
With control by N1-substituents, the switchable divergent C-H functionalization reaction of quinoxalin-2(1H)-ones is achieved for the synthesis of (Z)-enaminones and furo[2,3-b]quinoxalines using the combination of a copper catalyst and an oxidant. This new protocol features mild reaction conditions, readily available materials, and a broad substrate scope. Gram-scale and mechanistic studies were also investigated. Furthermore, the desired products exhibited excellent antitumor activity against A549, HepG-2, MCF-7, and HeLa cells, which were tested by MTT assay.
