A facile TBHP-mediated direct oxidative coupling of quinoxalin-2(1H)-ones with arylaldehydes has been developed under metal-free conditions. This method provided a convenient and efficient approach to various 3-acylated quinoxalin-2(1H)-ones from readily available starting materials with excellent regioselectivity. This reaction proceeded efficiently under mild conditions over a broad range of substrates and with functional group tolerance.

A novel and practical synthesis of 3-benzoylquinoxalin-2(1H)-ones from benzodiazepin-2-ones in two steps from commercially available starting materials is reported. The reaction was achieved in the presence of N-bromosuccinimide in DMSO which served both

Under basic conditions, benzopyranoquinoxalin-12-one leads to 3-(o-hydroxybenzoyl)-1H-quinoxalin-2-one.This ketone reacts with hydroxylamine and phenylhydrazine to give the expected derivatives or those of benzopyranoquinoxalin-12-one.
