nitroarylamines, allowing straightforward access to two classes of novelquinoxaline derivatives, is reported. The reaction proceeds with operational simplicity, an easily available catalyst system, and a broad substrate scope, and without the need for pre-functionalization, which offers the potential for further design of new reductive transformations of renewable resources into value-added products.
