Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an industrial method practically suitable for producing an optically active α-substituted prolines with short process and mild conditions.SOLUTION: A method of producing an optically active α-substituted prolines (6) includes (d) a step of obtaining an optically active N, α-substituted prolines (5) by hydrolysis of an optically active N, α-substituted proline amides (4), and (e) a step of obtaining an optically active α-substituted prolines (6) by eliminating the optically active N, and a protective group Rof the α-substituted prolines (5).
