PROCEDURE

实验过程

A suspension of di-n-butyl cis-1,3-dibenzyl-2-oxoimidazolidine-4,5-dicarboxylate (500 mg) in 0.1M phosphate buffer (pH 8.0, 45 ml) was treated with Pig Liver Esterase (manufactured by Sigma Lab., 1600 units, 10 mg) in a manner similar to that in Example 1 (1) to give (4S,5R)-1,3-dibenzyl-5-n-butyloxycarbonyl-2-oxoimidazolidine-4-carboxylic acid as an oily product. [α]D20 =+4.1° (c=1.55, CHCl3).
