Asymmetric homogeneous hydrogenation of α-(3-benzoylphenyl)acrylic acid (4), which is preparared in 90percent overall yield from (3-benzoylphenyl)acetic acid (1), affords (+)-α-(3-benzoylphenyl)propionic acid, (+)-5, in 93.7percent chemical and 67.4percent optical yield.The absolute configuration of (+)-5 is correlated with that of (+)-(S)-hydratropic acid via (+)-α-(3-benzylphenyl)propionic acid, (+)-6.The origin of the CD bands of (+)-6 is discussed and comparison of chiroptical data with those of (+)-(S)-hydratropic acid, reveals that (+)-6 has an S configuration.Since (+)-6 is chemically correlated with (+)-5, the absolute S configuration of this enantiomer is confirmed.
