In a method suitable for industrial application, an optically active N-aryl-β-amino acid compound is produced by the reaction of an aromatic amine and an optically active sulfonylated β-hydroxycarboxylic acid compound. The latter can be easily derived from a β-keto carboxylic acid compound.
showed high efficiency for the couplingreactions of aminoacids and inactive aryl halides to give N-aryl aminoacids. Under the catalytic conditions, not only α-amino acids, but also β-, γ-, and δ-amino acids have been coupled with aryl chlorides in moderate to high yields; in the case of optically pure β-amino acids as substrates, the optical purities of the coupling products retained.
