Design of C2-Symmetric Tetrahydropentalenes as New Chiral Diene Ligands for Highly Enantioselective Rh-Catalyzed Arylation of N-Tosylarylimines with Arylboronic Acids.

The article reports on the development of C2-symmetric tetrahydropentalenes as new chiral diene ligands for highly enantioselective Rh-catalyzed arylation of N-tosylarylimines with arylboronic acids. The application of this new ligand led the researchers to prove that 4a is efficient for asymmetric arylation of N-tosylarylimines with the use of arylboronic acids. Through this, researchers suggest that the broad range of enantiomerically diarylmethylamines could be easily prepared.
