direct intramolecular oxidative C(aryl)-H amidation reaction was developed for the synthesis of quinolino[3,4-b]quinoxalin-6(5H)-ones in moderate to excellent yields starting from readily available materials by tethering the adjacent N-methoxyamide and aryl portions in the presence of phenyliodine(III) bis(trifluoroacetate) at room temperature. This metal-free approach is a valuable addition to the traditional
