  描述：

  2-(RS)-[2-(methylthio)-2-oxoethyl]-1,4-butanedioic acid 4-(1,1-dimethylethyl) 1-methyl ester 在 sodium hydroxide 、 Alcalase 作用下， 以 丙酮 为溶剂， 反应 18.0h， 生成 (R)-2-(2-Methylsulfanyl-ethyl)-succinic acid 4-tert-butyl ester 、 (S)-2-(2-Methylsulfanyl-ethyl)-succinic acid 4-tert-butyl ester
  参考文献：
  名称：

  Chemo-enzymatic synthesis of chiral 2-substituted succinic acid derivatives

  摘要：

  Prochiral discrimination by the biocatalyst Alcalase(R), an enzyme preparation of subtilisin Carlsberg, was used to effect enantio- and regioselective monohydrolysis of a variety of(RS)-2-substituted succinate diesters to afford the corresponding half esters in modest to excellent enantiomeric excesses (>99%). Exploitation of malonate chemistry, as well as recycling of the unhydrolyzed isomer from the enantioselective hydrolysis, has resulted in a process which is both practical and economical.
