A set of phospholane–phosphoramidite ligands, which possess four elements of chirality, has been synthesized through a modular diastereoselective process. The ligands were applied in the Rh‐catalyzed asymmetric CC hydrogenation of several functionalized olefins with enantioselectivities of up to 99 % ee and a turnover frequency of up to 12 000 h −1 , in the Rh‐catalyzed hydroformylation of vinyl arenes with enantioselectivities of up to 79 % ee , and in the Ir‐catalyzed asymmetric CN hydrogenation of different aryl imines with enantioselectivities of up to 79 % ee .
