Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing an optically active amino acid using an inexpensive reagent suitable to industrial use. SOLUTION: The method comprises making an acid act on an imidazolidinone derivative having a structure represented by chemical formula (1) in a non-aqueous system. Thereby, the 1-arylethyl group of an imidazolidinone derivative having such a catalyst-poisoning functional group can be eliminated, which has been difficult by conventional methods, and furthermore, an N, N-crosslinked substituent constituting an imidazolidinone ring can be deprotected in a single step, thus enabling the objective amino acid or its ester to be easily produced.
