Chiral rhodiumcomplexes are widely used in asymmetric catalysis. Herein we describe a new approach to such chiral complexes featuring the intrinsically achiral benzoquinone ligands. The synthesis was achieved by the face-selective coordination of 2,5-substituted benzoquinones with rhodium bearing the readily available oxazoline-phenolate ligand. This chiral auxiliary ligand was subsequently replaced
