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.
