UNSYMMETRICALLY SUBSTITUTED PHOSPHOLANE CATALYSTS

Title:

UNSYMMETRICALLY SUBSTITUTED PHOSPHOLANE CATALYSTS

Document Type and Number:

WIPO Patent Application WO2006100169

Kind Code:

A3

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-catalysed 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.
