Heteroaromatic diphosphines as chiral ligands

摘要

Chiral diphosphines are constituted by an aromatic pentatomic biheterocyclic system, suitable to act as chiral ligands and complexes between the diphosphines and transition metals. They may be utilized as chiral catalysts in stereocontrolled reactions, such as diastereo- and enantioselective reduction reactions. Process is for the preparation of these chiral diphosphines; and process is for the preparation of these complexes and for their utilization as chiral catalysts in stereocontrolled reactions.
