Herein, we report an iridium-catalyzed asymmetric hydrogenation of hydantoin and thiazolidinedione derived exocyclic alkenes using our developed BiphPHOX as a ligand. The transformation shows good functional group tolerance, and gives the hydrogenated products with excellent yields (up to 99%) and enantioselectivities (up to 98% ee). A gram-scale reaction was also carried out, and provided the hydrogenated
