Different optically active amido esters, mixed acid esters, amido acids, and diamides derived from trans-cyclopropane-1,2-dicarboxylic acid were prepared from the commercially available diethyl (±)-trans-cyclopropane-1,2-dicarboxylate. The key step was the Rhodococcus rhodochrous IFO 15564 catalyzed hydrolysis of the corresponding racemic amide. The amidase present in this microorganism showed moderate
由可商购获得的(±)-反式-环丙烷-1,2-二羧酸二乙酯制备衍生自反式-环丙烷-1,2-二羧酸的不同光学活性的酰胺基酯,混合酸酯,酰胺酸和二酰胺。关键步骤是杜鹃红球菌IFO 15564催化水解相应的外消旋酰胺。该微生物中存在的酰胺酶对这些底物表现出中等至高的对映选择性。另外,一些酶法制备的环丙烷羧酸的简单有效的库尔修斯重排使我们能够以高收率和对映体过量获得旋光性β-氨基环丙烷羧酸衍生物。
