NOVEL CHIRAL PHOSPHORUS LIGANDS AND THE USE THEREOF IN THE PRODUCTION OF OPTICALLY ACTIVE PRODUCTS

摘要

The present invention relates to novel chiral phosphorus compounds which can be readily prepared from quinoline derivatives as inexpensive starting compound s and have the general formula I (see formula I) wherein R1, R2, R3, R4, R5 are chiral or achiral organic residues which are derived from substituted or unsubstituted straight or branched chain or cyclic aliphatic or aromatic groups and which, in the case of the pairs R1/R2 and R4/R5, may be interconnected. Further, the invention relates to the use of chiral phosphor us compounds of general formula I as catalysts or catalyst components in processes for the preparation of optically active products.
