The present invention relates to novel chiral phosphorus compounds which can be readily prepared from quinoline derivatives as inexpensive starting compounds 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 phosphorus compounds of general formula I as catalysts or catalyst components in processes for the preparation of optically active products.
L'invention concerne de nouveaux composés chiraux de phosphore que l'on peut obtenir de façon simple à partir de dérivés de quinoline, comme matières premières économiques, et qui ont la formule générale (I), où R<1>, R<2>, R<3>, R<4>, R<5> sont des restes organiques chiraux ou achiraux qui sont dérivés de groupes aliphatiques ou aromatiques à chaîne linéaire, ramifiés ou cycliques substitués ou non substitués et qui, dans le cas des paires R<1>/R<2> et R<4>/R<5>, peuvent être liés ensemble. L'invention concerne également l'utilisation de composés chiraux de phosphore de la formule générale (I) comme catalyseurs ou constituants de catalyseurs dans les procédés de production de produits optiquement actifs.
