Polyfunctional derivatives of 3-aminopyrrole have been synthesized from several substituted β-enamino nitriles using Torp-Ziegler cyclization. These compounds are starting materials for further conversions, particularly for the synthesis of pyrrolo[3,2-d]

The reaction of 1-benzyl-5-cyano-6-dimethylaminomethylene-1,6-dihydro-4-pyrimidinone with acid leads to 5-benzyl-1,2,7,8-tetrahydropyridopyrimidine-1,8-dione, whereas the reaction with ammonia leads to a mixture of 3-cyano-4-benzylamino-2-pyridone
