Chiral diphosphine ligands based on camphor: Synthesis and applications in asymmetric hydrogenations
The synthesis of a novel class of atropisomer chiral diphosphine ligands with a bornene framework is described. The new ligands showed in Rh catalyzed asymmetric hydrogenation of α- and β-enamides very high ee's (more than 99%).
