Abstract
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.
