For the purpose of elucidating the structural relationship between lathyrism and inhibition of necrosis induced by CCl4 in the liver of the rat, many compounds related to aminoacetonitrile were synthesized. N-Aminoacylaminoacetonitriles (VIII, XIV) were synthesized from phthaloylaminoacylaminoacetonitriles. VIII were converted to 2-hydroxyimino-5-oxopiperazine derivatives (XV) and 5-oxo-2-thio-piperazines (XX). Preparations of N-(N-acylaminoacyl) aminoacetonitriles were also described. Further, N-α-hydroxyacylaminoacetonitriles were prepared from chloralides of α-hydroxyacids with aminoacetonitrile. In addition, XV (R=H) was converted to 2-acetamino-5-acetoxypyrazine by treatment with acetic anhydride.
为了阐明贻贝症与四氯化碳诱导的大鼠肝脏坏死抑制之间的结构关系,合成了许多与氨基乙腈相关的化合物。N-氨基酰氨基乙腈(VIII,XIV)是从邻苯二甲酰氨基酰氨基乙腈合成的。VIII被转化为2-羟基亚胺-5-氧杂哌嗪衍生物(XV)和5-氧-2-硫杂哌嗪(XX)。还描述了N-(N-酰氨基酰)氨基乙腈的制备。此外,N-α-羟基酰氨基乙腈是由α-羟基酸的氯化物与氨基乙腈反应制备的。此外,通过用醋酸无水物处理,XV(R=H)被转化为2-乙酰氨基-5-乙酰氧基吡唑。
