OPTICALLY ACTIVE PHOSPHITES AND PHOSPHORAMIDES BEARING BIPHENOL SKELETONS WITH AXIAL CHIRALITY, AND THEIR USE IN CATALYTIC ASYMMETRIC REACTIONS

摘要

Novel optically active ligands which are mondentate phosphites and phosphoramidites, and bidentate phosphites and phosphoramidites; optically active catalysts comprising a reaction mixture of the ligand and a transition metal or its compounds; and processes of using the optically active catalysts to produce optically active compounds.
