Reaction |
- Biaryl bisphosphine ligand with narrow dihedral angle. The DM-SEGPHOS ligand, as the ruthenium complex, gives superior enantioselectivity and diastereoselectivity in the asymmetric hydrogenation of α-substituted-β-ketoesters.
- Copper catalyzed enantioselective [3 + 2] cycloaddition as a route to γ–amino ketones and 3-pyrrolidinones.
- Palladium catalyzed enantioselective addition of malonates to dihydroisoquinolines.
- Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation.
- Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone. See 44-0098 for Ru catalyst.
- Diastereoand enantioselective ruthenium-catalyzed hydrohydroxyalkylation of 2-silyl-butadienes.
- Asymmetric [2+2+2] cycloaddition.
- Linear selective C-H activation.
