Catalytic asymmetric hydrogenation of aldehydes.
Racemic alpha-arylaldehydes provide the corresponding primary alcohols via dynamic kinetic resolution in excellent enantioselectivities and yields upon hydrogenation using a Noyori ruthenium catalyst; for example, the biologically active (S)-enantiomer of the non-steroidal anti-inflammatory drug ibuprofen could be synthesized via catalytic enantioselective hydrogenation of aldehyde followed by oxidation with potassium permanganate in 76% isolated yield and 96 : 4 er.
