    Description / Table of Contents: Structural Studies on 2-(Arylimino)imidazolidines and 2-(Arylamino)imidazolines with the Aid of Proton- and Carbon-13 Magnetic ResonanceProton- and carbon-13 spectra indicate that the 2- (arylamino)imidazolines 1 and 2 exist as 2-(arylimino)imidazolidine tautomers. The carbon-13 magnetic resonance is shown to be the more significant method.
    Notes: Protonen- und 13C-NMR-Spektren zeigen an, daß die 2-(Arylamino)imidazoline 1 und 2 bevorzugt als 2- (Arylamino)imidazoline-Tautomere vorliegen. Dabei erweist sich die 13-C-Resonanz als die aussagekräftigere Methode.

    Description / Table of Contents: Unusual Course of the Reaction of α-Acyl-γ-butyrolactones with 2-(2,6-Dihalogenophenylimino)imidazolidinesHeating of α-acyl-γ-butyrolactones 1 with 2-(2,6-dihalogenophenylimino)imidazolidines 5 in HMPT unexpectedly leads to 7-halogeno-2-,6-dihydro-4-alkyl-5,6-ethano-1H- [1,4]diazepino-[1,7-a]benzimidazoles 7 in low yields. The structures of 7 are derived from spectroscopic data, oxidative degradation to benzimidazole derivative 9 and an X-ray structure analysis. A possible pathway for the formation of 7 is discussed.
    Notes: α-Acyl-γ-butyrolactone 1 liefern beim Erhitzen mit 2-(2,6-Dihalogenphenylimino)imidazolidinen 5 in HMPT unerwartet in geringen Ausbeuten 7-Halogen-2,6-dihydro-4-alkyl-5-,6-ethano-1H-[1,4]diazepino[1,7-a]benzimidazole 7, deren Struktur durch die spektroskopischen Daten, Abbauversuche und eine Röntgenstrukturanalyse abgeleitet wird. Der mögliche Bildungsweg dieser Verbindungen wird diskutiert.

    Description / Table of Contents: Syntheses in the 2-Aminoimidazoline SeriesThe action of substituted aminoalkyl halides on 2-arylaminoimidazolines 1 leads to compounds 4, in which the basic side chain is situated at the bridging nitrogen atom between the phenyl group and the imidazoline ring. The new imidazolines 4 are isomeric with the derivatives 5, correspondingly substituted at the imidazoline nitrogen. The synthesis of 5 has been shown. The NMR-spectra, serving as proof for the structure, and the mechanism of reaction are discussed.
    Notes: Die Einwirkung von substituierten Aminoalkylhalogeniden auf 2-Arylamino-imidazoline 1 führt zu Verbindungen 4, bei denen die basische Seitenkette am Brückenstickstoff zwischen Phenyl-Rest und Imidazolin-Ring haftet. Die neuen Imidazoline 4 sind isomer den am Imidazolinstickstoff entsprechend substituierten Derivaten 5, deren Synthese aufgezeigt wird. Die NMR-Spektren (Abb. 1), die als Kriterium der Struktur dienen, sowie der Reaktionsmechanismus werden diskutiert.

    Description / Table of Contents: Cyclizing Reactions with 2-AminoimidazolinesThe reaction of 3-amino-3-chloroacryloyl chloride 6 with 2-arylaminoimidazolines 1a affords the imidazo[1,2-a]pyrimidinones 7 or 8 depending on the solvent used. In the case of the 2-aminoimidazolines 1b and 1c only the imidazo[1,2-a]pyrimidinones 7 are formed both in polar and nonpolar solvents.  -  The mechanism of the reaction is discussed.
    Notes: Bei der Reaktion der 3-Amino-3-chloracryloylchloride 6 mit den 2-Arylaminoimidazolinen 1a entstehen in Abhängigkeit vom verwendeten Lösungsmittel die Imidazo[1,2-a]pyrimidinone 7 oder 8. Im Falle der 2-Aminoimidazoline 1b und 1c entstehen sowohl in polaren als auch in unpolaren Lösungsmitteln lediglich die Imidazo[1,2-a]pyrimidinone 7.  -  Der Reaktionsmechanismus wird diskutiert.
