Enantioselective Borylation of Aromatic C−H Bonds with Chiral Dinitrogen Ligands

Enantioselective C−H borylation: The first Ir-catalyzed enantioselective borylation of aromatic C−H bonds was developed with up to 98:2 er. The success of this reaction relies on a newly developed catalyst that derives from an iridium precursor and a chiral quinolinyl oxazoline ligand.
