The present invention provides a process for preparing optically active azetidine-2-carboxylic acids using readily available reagents of relatively low price in the industry. Thus, there is provided optically active azetidine-2-carboxylic acid, and a process for producing the same by subjecting optically active N-(alkylbenzyl)azetidine-2-carboxylic acid represented by the formula (1): ##STR1## to hydrogenolysis in the presence of a catalyst.
本发明提供了一种使用工业上价格相对较低的易得试剂制备光学活性氮杂环丙
氨酸的方法。因此,提供了光学活性氮杂环丙
氨酸以及一种通过在催化剂存在下将式(1)表示的光学活性N-(烷基苯基)氮杂环丙
氨酸进行氢解的方法。
