title: Chiral dienes as "ligands" for borane-catalyzed metal-free asymmetric hydrogenation of imines.
abstract: This paper describes a highly enantioselective metal-free hydrogenation of imines using chiral dienes as "ligands" for the generation of catalysts with HB(C6F5)2 by hydroboration in situ to furnish a variety of chiral amines with up to 89% ee, which provides a practical strategy for the development of novel chiral frustrated Lewis pairs for asymmetric hydrogenation.
