Li, Long;Han, Feng;Nie, Xin;Hong, Yubiao;Ivlev, Sergei;Meggers, Eric research published 《 Complementing Pyridine-2,6-bis(oxazoline) with Cyclometalated N-Heterocyclic Carbene for Asymmetric Ruthenium Catalysis》, the research content is summarized as follows. A strategy for expanding the utility of chiral pyridine-2,6-bis(oxazoline) (pybox) ligands for asym. transition metal catalysis is introduced by adding a bidentate ligand to modulate the electronic properties and asym. induction. Specifically, a ruthenium(II) pybox fragment is combined with a cyclometalated N-heterocyclic carbene (NHC) ligand to generate catalysts for enantioselective transition metal nitrenoid chem., including ring contraction to chiral 2H-azirines (up to 97% ee with 2000 TON) and enantioselective C(sp3)-H aminations (up to 97% ee with 50 TON).
