    Description / Table of Contents: Preparation of Bi- and Tricyclic PyrrolesHerrn Prof. Dr. Dr. h. c. R. Huisgen in freundschaftlicher Verbundenheit zum 60. Geburtstag gewidmet.Phthalimidoalkane-1,4-diones smoothly react with aromatic and aliphatic amines to give the substituted (phthalimidoalkyl)pyrroles 1 - 16. Hydrazinolysis of these compounds yields tricyclic 4H-pyrrolo[1,2-a][1,4]benzodiazepines 17 - 23 and bicyclic pyrrolo[1,2-c]imidazoles 24, 25, pyrrolo[1,2-c]pyrimidines 26, 27, pyrrolo[1,2-a]pyrazines 28 - 30, and pyrrolo[2,1-d][1,4]diazepines 31, 32, respectively.
    Notes: Phthalimidoalkan-1,4-dione lassen sich leicht mit aromatischen und aliphatischen Aminen zu substituierten (Phthalimidoalkyl)pyrrolen 1 - 16 umsetzen; die anschließende Hydrazinolyse der Produkte liefert die tricyclischen 4H-Pyrrolo[1,2-a][1,4]benzodiazepine 17 - 23 bzw. die bicyclischen Pyrrolo[1,2-c]imidazole 24, 25, Pyrrolo[1,2-c]pyrimidine 26, 27, Pyrrolo[1,2-a]pyrazine 28 - 30 und Pyrrolo[2,1-d][1,4]diazepine 31, 32.
