摘要: β-(3,4-二氨基苯基)-α-氨基丙酸二盐酸盐是合成药物的一个重要中间体。从文献中只见到苏联列宁格勒药物研究所在1966年报导的合成方法:以5-甲基苯并[2,1,3]硒二氮杂茂为原料依次与NBS、NaC(NHCOCH3)(COOC2H5)2、H2S/NH4OH及HCl,H2O作用而制得。其中5-甲基苯并[2,1,3]硒二氮杂茂的制备需4—5步。

Abstract: Anew synthetic route for β-(3,4-diaminophenyl)-alaninc dihydrochloride by using P-nitrobenzaldehydc and N-benzoylglycine as starting substrates is reported. Some of the intermediates in this route are new compounds.Our method,compared with that of V.G.Pesin ct al.[1], has the advantages that the starting substrates are easily available, the reacting conditions are moderate and the operations are simple.
