Direct synthesis of novel quinoxaline derivatives via palladium-catalyzed reductive annulation of catechols and nitroarylamines

2020 
Here,reported is a palladium-catalyzed new hydrogenative annulation reaction of catechols and nitroarylamines, allowing straightforward access to two classes of novel quinoxaline derivatives. The reaction proceeds with operational simplicity, easily available catalyst system, broad substrate scope, and no need for pre-functionalization, which is expected to inspire others to discover hydrogen-stroage materials, develop new functional molecules, and design reductive transformations of renewable resources into value-added products.
