(S)-2-aralkyl-3-chloropropionic acid and process for the preparation thereof

摘要

The present invention provides a novel 2-aralkyl-3-chloropropionic acid and a process for the preparation thereof. A novel 2-aralkyl-3-chloropropionic acid is represented by the general formula (1): lly hydrogenating a (Z)-2-aralkylidene-3-chloropropionic acid represented by the general formula (II): <IMAGE> (II) with a complex of a bidentate phosphine with ruthenium as a catalyst in the presence of a tertiary amine.
