title: Organocatalytic enantioselective hetero-Diels-Alder reaction of aldehydes and o-benzoquinone diimide: synthesis of optically active hydroquinoxalines.
abstract: A highly enantioselective inverse electron demand hetero-Diels-Alder reaction of o-benzoquinone diimide and aldehydes has been developed by secondary amine catalysis, giving a facile protocol to access a variety of chiral hydroquinoxalines under mild conditions.
