摘要：
An I-2-DMSO promoted remote difunctionalization reaction of anthranils is reported. This cross-coupling process realizes simultaneous N1-and C5-dicarbonylation of anthranils with a highly atom-and step-economy. The mechanism involves the copper-catalyzed N-O bond cleavage of anthranils and the construction of a new C-C and a C-N bond respectively. The transformation proceeds smoothly in gram-scale, and the product of the reaction could be transformed into other valuable heterocyclic structures. (c) 2022 Elsevier Ltd. All rights reserved.
