A Novel Bisoxazoline‐Imidazolium Salt in Ytterbium‐Catalyzed Asymmetric Reduction of Ketone

Abstract

Chiral N-heterocyclic carbene (NHC), a privileged ligand for transition metals, has had a profound impact on organometallic chemistry. The monodentate and bidentate chiral carbenes have been developed significantly, while the tridentate ones have been less exploited. Herein, we designed and [a] Y.
