Chiral discrimination in the intramolecular abstraction of allylic hydrogens by benzophenone triplets

Using two diastereomeric compounds containing benzophenone and olefin units, significant chiral discrimination has been found in all the photophysical and photochemical processes involved in intramolecular hydrogen abstraction: overall quenching of benzophenone triplets, actual hydrogen abstraction step and (pi)-quenching.
