Phenyl substituted pyrrolinones |
| abstract |
The invention relates to pyrrolinones of formula (1) ##STR1## wherein R 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. n The invention also relates to aminodicarboxylates of formula (2) ##STR2## wherein R 1 is a defined in claim 1 and R and R' are the same or different and are alkyl or aryl. n The aminodicarboxylates of formula (2) are prepared by condensing a disuccinate of the formula n n R'OOCCH.sub.2 CH.sub.2 COOR n n with a nitrile of the formula R 1 CN, in the presence of a strong base and zinc chloride. n 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. n The compounds of formulae (1) and (2) are valuable intermediates for pigments. |
