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 a combination of primary or secondary aromatic or aliphatic amines with orthocarboxylic esters upon a variety of open-chain CH2-acidic molecules gives N-substituted aminoalkylidene derivatives.The method is highly recommended for methylene
