Conclusions

When piperazine, p-xylylenediamine and hexamethylenediamine are reacted with the imides of citraconic and maleic acids in the absence of moisture the amines add to the double bond of the imide rings. Two stereoisomeric diimides of the corresponding alkylenebisaspartic and methylbisaspartic acids are formed here.
