Enantioselective addition of phenylacetylene to N-aryl arylimines catalyzed by Cu(II)-pyridine containing N-tosylatedaminoimine ligand complex.
Chiral tridentate N-tosylated pyridine-containing ligands were prepared and used in the Cu(II)-catalyzed enantioselective addition of phenylacetylene to N-aryl arylimines. Moderate to high enantioselectivities (up to 95% ee) were obtained in very mild reaction conditions.
