Development of Quinoline-Derived Chiral Diaminocarbene Ligands and Their Transition Metal Complexes: Synthesis, Structural Characterization, and Catalytic Properties
N-Heterocyclic carbenes (NHCs) bearing a fused tricyclic skeleton have recently been developed as a new type of promising ligands for asymmetric transition metal catalysis. In this article, two kinds of chiral tricyclic NHCs featuring partially reduced 2,2′-bisquinoline- and 2-(piperidin-2-yl)quinoline skeleton have been prepared via a direct asymmetric hydrogenation synthetic strategy. Their Rh- and Pd-complexes were synthesized and characterized by NMR and high-resolution mass spectra as well as X-ray crystallography. The electronic effect and steric environment of these new chiral tricyclic NHCs were systematically evaluated by determining the Tolman electronic parameter (TEP) and the percent buried volumes (%V-bur) of the corresponding metalated complexes. It was revealed that these new ligands possess strong electron-donating properties and high steric demands. Additionally, these chiral NHC ligands have been successfully employed in the enantioselective palladium-catalyzed intramolecular alpha-arylation in high yield with good enantioselectivity (up to 80% ee). It is noteworthy that the rigid fused tricyclic rings and bulky ortho substituents can greatly improve the electron-donating property and chiral induction ability of these chiral NHC ligands.
