摘要: The invention relates to pyrrolinones of formula (1) ##STR1## wherein R.sub.1 is an alkyl group containing at least 2 carbon atoms, an aralkyl group, an isocyclic or heterocyclic aromatic radical and R is an alkyl or aryl group.The invention also relates to aminodicarboxylates of formula (2) ##STR2## wherein R.sub.1 is a defined in claim 1 and R and R' are the same or different and are alkyl or aryl.The aminodicarboxylates of formula (2) are prepared by condensing a disuccinate of the formulaR'OOCCH.sub.2 CH.sub.2 COORwith a nitrile of the formula R.sub.1 CN, in the presence of a strong base and zinc chloride.The pyrrolinones of formula (1) are obtained by reacting the aminodicarboxylates of formula (2) in the presence of a strong base in an organic solvent.The compounds of formulae (1) and (2) are valuable intermediates for pigments.
