chiral sulfonated binap catalyst for asymmetric synthesis of ..

In an effort to synthesize enantioenriched dihydroisoquinolinones from chrial -allyl carboxamides via a diastereoselective carbopalladation, our group came across an interesting effect of added amine. In this study it was found that dr’s could be significantly improved when the reaction was run in the presence of tertiary amine bases (i.e. PMP). This approach afforded a diverse range of enantioenriched scaffolds to be synthesized while retaining the valuable iodide functional group handle. This method was used the asymmetric formal synthesis of the alkaloid natural (+)-corynoline (Scheme 6).

Noyori asymmetric hydrogenation - Wikipedia

Enantiomerically pure diphosphines play an important role in various homogeneous metal-catalysed asymmetric reactions. This study shows the high catalytic performances of atropisomeric ligands DIFLUORPHOS, SYNPHOS and SYNPHOS analogues for some C–H and C–C bond-forming processes as well as for the synthesis of biorelevant targets.

Two years were necessary to find that appropriate reaction condition.
Nevertheless, the BINAP-Rh complex became famous not because of asymmetric hydrogenation, but because of its successful application to the asymmetric synthesis of menthol which was carried out in a joint collaboration with Prof.

Many chemists thought that there was not much left to be investigated in the field of asymmetric hydrogenation, but it turned out in contrast that the study had only just begun.
When I started my research on asymmetric hydrogenation, I made up my mind to achieve a perfect asymmetric synthesis.
