We have evaluated a wide range of iridium complexes derived from chiral oxazoline‐based N,P ligands for the asymmetric hydrogenation of imines and identified three efficient catalysts. These catalysts are readily synthesized by straightforward convenient routes and are air and moisture stable. In the reduction of acetophenone N‐arylimines and related acyclic substrates, excellent enantioselectivities

Enantiopure terphenyl presenting two ortho-located chiral axes having the following structural formula (I): their process of synthesis and their use as mono or bidentate ligands for asymmetric organometallic reactions, as organocatalysts, as chiral base and as generator, with metal, of isolable chiral metallic complexes for applications in asymmetric catalysis and others.
