Ryōji Noyori developed chiral catalysts for asymmetric hydrogenation, in which addition of hydrogen preferentially produces one enantiomer. This work was recognized by the 2001 Nobel Prize in Chemistry.[ref]
The catalyst creates competing reaction paths with different activation free energies. It can thus favour one molecular handedness while being regenerated, linking catalysis with stereoselectivity.
