The enantioselective synthesis of 2-aryl-substituted 2,3-dihydroquinolin-4-ones, a class of heterocyclic compounds with interesting biological activities, has been achieved through a Brønsted acidcatalyzed enantioselectiveintramolecular Michael addition. The products are available in moderate to high yields and with good enantioselectivities. Graphical Abstract Asymmetric Brønsted Acid-catalyzed Intramolecular
