    Abstract An efficient and direct carbonylation of aminoquinoline benzamides has been developed using abundant and inexpensive Ni(OAc)₂·4H₂O as the catalyst and carbon monoxide as a cost-efficient C1 building block. This process features good functional-group tolerance and can be conducted on gram scale. The directing group can be easily removed under mild conditions.

    Abstract An efficient and direct oxidative reaction for the construction of 1,4-dihydroquinoxaline-2,3-diones has been developed. A range of oxidative products are obtained with satisfactory yields (up to 99%). This practical method features transition metal free, surfactant free, chromatography free, mild reaction conditions, good functional group tolerance and easy scale-up synthesis. Furthermore, it provided a convenient approach for the synthesis of one kind of known inhibitor for α-glucosidase. This mechanistic study shows that this transformation is not a radical process.

    Abstract An inexpensive electrochemical induction system was used for the efficient reductive defunctionalization of sulfoximines through a radical pathway. This practical and robust strategy could be used for the removal of the S═N bond-directing group from various sulfoximines. The practicability of this method was demonstrated by its mild conditions, simple operation, one-pot procedure, gram-scale synthesis, and the undivided cell. Furthermore, preliminary mechanistic studies suggested that the reaction might proceed via a homocoupling reaction and a denitrification procedure.

    Abstract 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.
