Abstract
The present invention provides a method for producing chiral amines, comprising asymmetric transfer hydrogenation of imine compounds in the presence of a hydrogen donor compound and an iridium(III) complex having a chiral prolinamide compound as a ligand. The present invention is useful for production of chiral amines in an efficient manner in terms of their optical and chemical yields.
