Abstract
Easily synthesized1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid {[MOEI]-BSA} as a novel catalyst efficiently promoted the synthesis of quinoxaline derivatives via condensation of various diamines with 1,2-dicarbonyl compounds at room temperature conditions in ethanol. This research provides a new method for the synthesis of quinoxalines in good to excellent yields with little catalyst loading. The catalyst could be recycled and reused several times without any loss of efficiency.
