Enantiomers of 3-methyl-2-aziridinecar☐ylic acids (1-d and 1-l) and 2-aziridinecar☐ylic acids (2-d and 2-l) reacted easily with thiophenol, cysteine and glutathione in aqueoussolution or in sodium phosphate buffer solution at room temperature and gave predominantly β-aminoacid derivatives with sulfur substituents at their α-position.

An optically active amino acid derivative is produced by N-protecting an optically active 3-haloalanine derivative followed by cyclization, or cyclizing this derivative followed by N-protection to thereby give an optically active N-protected-aziridine-2-carboxylic acid derivative which is protected by a benzenesulfonyl group substituted by nitro at the 2- and/or 4-positions and then treating this product with an organic metal reagent, or by N-protecting an optically active 3-haloalanine derivative to thereby give N-protected-aziridine-2-carboxylic acid which is protected by a benzenesulfonyl group substituted by nitro at the 2- and/or 4-positions and then treating this product with an organic metal reagent. According to this process, natural and unnatural optically active amino acids can be produced from inexpensive materials by using simple procedures.
