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 c...

The Front Cover shows the synthesis of various quinoxalines in nothing but “hot water”. Aromatic can be synthesized down to 10 min from starting compounds stoichiometric ratio water at 230 °C through microwave-assisted hydrothermal synthesis. synthetic approach is tolerant a broad array functional groups and combined with protecting group strategies. A large-scale computational comparison all d...
