Benzophenone-derived catalyst with self-adaptation: highly enantioselective hydrogenation irrespective of ketone substrates.

[摘要]：The Ru complex with the tropos benzophenone-derived diphosphine ligand could be chirally controlled to a single chiral conformation instantaneously with a chiral diamine to attain high enantioselectivity in the asym. hydrogenation irresp. of ketone substrates. In the asym. hydrogenation of not only 1-acetonaphthone but also 9-acetylanthracene, the tropos Ru complex fits well with the substrate change to give high catalytic activity and enantioselectivity upon addn. of silver salts such as AgOTf.
