  摘要：

  trans-Aziridine-2,3-dicarboxylic ester was used to prepare the required beta-chlorohydroxamic acid used in the synthesis of the title compound. The trans configuration of the asparagine analogue was established by hydrogenolysis to erythro-beta-hydroxyasparagine amide. Neither the title compound nor the intermediate aziridinehydroxamic acid (8) showed significant activity against the L1210 and P-388 tumors. The title compound was inactive as an inhibitor of asparagine synthetase from Novikoff hepatoma and did not inhibit the growth of some 25 bacteria and fungi.

  Crystalline threo-and erythro-β-hydroxy-l-asparagine were prepared via asymmetric hydrolysis of the corresponding hydroxy-l-aspartic acid diamide by leucine aminopeptidase. The isomers of hydroxy-l-asparagine obtained were compared with the natural hydroxyasparagine isolated from human urine with respect to optical rotation and chromatography. From the results it is concluded that the spacial configuration of the natural product is that of erythro-β-hydroxy-l-asparagine. Additional studies were also carried out to prepare threo- and erythro-β-hydroxy-Dl-asparagine from the corresponding hydroxy-Dl-aspartic acid diamide without the enzyme.

  通过使用白氨酸氨肽酶对相应的羟基-L-天冬氨酸二酰胺进行不对称水解，制备了结晶的threo和erythro-β-羟基-L-天冬氨酸。获得的羟基-L-天冬氨酸异构体在光学旋转和色谱方面与从人尿中分离出的天然羟基天冬氨酸进行了比较。结果表明，天然产物的空间构型为erythro-β-羟基-L-天冬氨酸。此外，还进行了额外的研究，以在没有酶的情况下从相应的羟基-DL-天冬氨酸ref=https://www.molaid.com/MS_47888 target="_blank">天冬氨酸二酰胺制备threo和erythro-β-羟基-DL-天冬氨酸ref=https://www.molaid.com/MS_47888 target="_blank">天冬氨酸。
