chemistry and drug discovery. A highly efficient copper-catalyzed asymmetric conjugated reduction of chromones is developed to give chiral chromanones with good yields (80–99%) and excellent ee values (94–>99% ee). Particularly noteworthy is that chiral thiochromanones are also constructed using this method in 74–87% yields with 96–97% ee. The established asymmetric synthesis paves the way for their
