A highly efficient (aS)-Ir/In-BiphPHOX-catalyzed asymmetric hydrogenation of substituted 2H-chromenes and substituted benzo[e][1,2]oxathiine 2,2-dioxides is described. A series of 2H-chromenes and benzo [e] [1,2]oxathiine 2,2-dioxides were hydrogenated to give the target products in high yields (92-99%) with excellent enantioselectivities (up to 99.7% ee) using our catalytic system. This reaction provides a direct and efficient method for the construction of chiral bent six-membered oxygen-containing compounds.
