Metal-free oxidative coupling of quinoxalin-2(1<i>H</i>)-ones with arylaldehydes leading to 3-acylated quinoxalin-2(1<i>H</i>)-ones

Abstract

An efficient protocol for the synthesis of 3-aroylquinoxalin-2(1<italic>H</italic>)-ones has been developed <italic>via</italic> a metal-free oxidative cross-coupling reaction of quinoxalin-2(1<italic>H</italic>)-ones with aryl aldehydes under mild conditions with good yields.
