Abstract
In contrast with the imines formed from monoaminoalkanes and alpha,omega -d iaminoalkanes with pyrrole-3,4-dicarboxaldehydes, which exist in a tautomer ic 3H-pyrrole form, pyrrole-2-carboxaldehydes and -2,5-dicarboxaldehydes re act with amines to produce 1H-pyrrolyi-methylenimines. Pyrrole-2,5-dicarbox aldehydes with 1,2-diamino-ethane and with 1,3-diaminopropane yield symmetr ical macrocyclic systems, contrary to earlier reports.
