Chiral phosphorus ligands and the use thereof in the production of optically active products

   
   

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 ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 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 R.sup.1 /R.sup.2 and R.sup.4 /R.sup.5, 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.

A invenção atual relaciona-se aos compostos chiral do phosphorus da novela que podem prontamente ser preparados dos derivatives do quinoline enquanto compostos começando baratos e têm o ## geral do ## STR1 da fórmula I wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 são os resíduos orgânicos chiral ou achiral que são derivados do substituído ou corrente reta ou ramificada unsubstituted ou grupos aliphatic ou aromatic cíclicos e que, no exemplo dos pares R.sup.1 /R.sup.2 e R.sup.4 /R.sup.5, podem ser interconectados. Mais mais, a invenção relaciona-se ao uso de compostos chiral do phosphorus da fórmula geral I como catalizadores ou componentes do catalizador nos processos para a preparação de produtos ótica ativos.
