SEGPHOS is a chiral ligand that is used in asymmetric synthesis. [cite journal | author = Shimizu, H., Nagasaki, I., Matsumura, K., Sayo, N., Saito, T. | title = Developments in Asymmetric Hydrogenation from an Industrial Perspective | year = 2007 | journal = Acc.

This was predicted and then confirmed to increase the enantioselectivity and activity of metal complexes of SEGPHOS.
