DuPhos is a class of organophosphorus compound that are used ligands for asymmetric synthesis. The name DuPhos is derived from (1) the chemical company that sponsored the research leading to this ligand's invention, DuPont and (2) the compound is a diphosphine ligand type. Specifically it is classified as a C2-symmetric ligand, consisting of two phospholanes rings affixed to a benzene ring. The ligand was introduced in 1991 by M.J. Burk and first demonstrated in asymmetric hydrogenation of certain enamide esters to amino acid precursors:
