실험 절차

A suspension of di-n-propyl cis-1,3-dibenzyl-2-oxoimidazolidine-4,5-dicarboxylate (200 mg) in 0.1M phosphate buffer (pH 8.0, 20 ml) was treated with Pig Liver Esterase (manufactured by Sigma Lab., 640 units, 4 mg) in a manner similar to that in Example 1 (1) to give (4S,5R)-1,3-dibenzyl-5-n-propoxycarbonyl-2-oxoimidazolidine-4-carboxylic acid (164 mg). M.P., 75°-90° C. [α]D20 =+2.1° (c=1, CHCl3).
