An efficient copper-catalyzed electrophilicamination strategy has been established for the rapid synthesis of N-aryl-2-aminophenones from readily available arylboronic acids/esters and anthranils. This protocol features good functional group tolerance, broad substrate scope, and operational simplicity. Moreover, a tandem C–H borylation and C–N coupling protocol has also been developed to transform

A copper-catalyzed approach for the synthesis of acridones via C–Cbondcleavage and intramolecular cyclization using air as the oxidant under neutral conditions is described. This transformation offers an alternative method to prepare medicinally important acridones and a new strategy for C–Cbondcleavage.
