ABSTRACT:
The present invention provides an effective method for the production of optically active N-aryl-β-amino acid compounds, which at the same time is suitable for industrial production. In the method of the present invention optically active sulfonylated β-hydroxycarboxylic acid compounds, which are readily derived from β-keto carboxylic acid compounds, are reacted with aromatic amines to produce optically active N-aryl-β-amino acid compounds.
