Abstract

An efficient, simple, and green procedure for the synthesis of quinoxaline derivatives is described. The condensation of 1,2-diamines with 1,2-diketones using lithium bromide (LiBr) in H2O/EtOH as a green reaction media at room temperature affords the title compounds in high to excellent yields and in short reaction times.
