Abstract

Zusammenfassung Die bifunktionellen Titelverbindungen 2 reagieren mit Acylierungs-, Carbamoylierungs-und Sulfinylierungs-Reagenzien meist an der primären Amino-Gruppe der Hydrazin-Funktion. N, N′-Carbonyldiimidazol greift beide funktionelle Gruppen von 2 an und bedingt die Umwandlung in 1 H-1, 2, 4, 5-Tetrazepin-3-on-Derivate 8. Die säureinduzierte 1, 4-Eliminierung von Phenylhydrazin aus 2 führt zur Bildung der ...
