C–H bond acylation of quinoxalin-2(1H)-ones. In this method, α-oxo-carboxylic acids served as efficient acylating reagents to in situ generate the required active acyl radical. Its excellent chemoselectivity allowed the molecular diversity of 3-acyl quinoxalin-2(1H)-ones to be achieved by convenient functionalizations of both N1- and C3-positions.
