In this paper we describe two new basic conditions for the synthesis of quinoxaline 1,4-dioxide derivatives in moderate to good yields. These conditions, exemplified by the use of K 2 CO 3 in acetone or KF/Al 2 O 3 in the absence of an organic solvent, were reproducible and applicable to the synthes
