Lowering the ketone: RuII complexes containing a chiral pyridyl‐based 1H‐pyrazolyl–oxazolinyl NNN ligand were synthesized and structurally characterized by X‐ray crystallographic studies. These complexcatalystsefficiently catalyzed the asymmetrictransferhydrogenation of ketones, reaching up to 99 % ee for the desired products (see scheme).
