Asymmetrichydrogenation has evolved as one of the most powerful tools to construct stereocenters. However, the asymmetrichydrogenation of unfunctionalized tetrasubstituted acyclic olefins remains the pinnacle of asymmetric synthesis and an unsolved challenge. We report herein the discovery of an iridium catalyst for the first, generally applicable, highly enantio- and diastereoselective hydrogenation
