Abstract:
The present invention is based on new ligand systems of the general formula (I). These ligand systems can be used advantageously in transition metal-catalyzed asymmetric syntheses. Likewise encompassed are the transition metal complexes thus prepared, a process for preparing the ligands and the use of the complexes in asymmetric synthesis.
