Binol-Derived Monodentate Phosphites and Phosphoramidites with Phosphorus
Centers: Novel Ligands for Transition-Metal Catalysis. — A new
21- 036 Stereogenic
class of monodentate P-chiral phosphorus ligands is prepared, most of them being highly efficient in Rh-catalyzed asymmetric olefin hydrogenation. In the majority of the experiments, the stereochemical outcome is controlled by the configuration of the BINOL
moiety. Special emphasis is given for the behavior of ligand (IVb) which shows the best
performance when used as mixture of diastereomers. — (REETZ*, M. T.; MA, J.-A.;
