Abstract

Zusammenfassung Umwandlungen von einigen heterocyclischen Cyanoamino- Verbindungen in verschiedene heterocyclische Systeme werden beschrieben. s-Triazolo-(1, 5-a) azine konnten in einem direkten Syntheseschritt oder über die substituierten Aminotetrazole, substituierten 3-Amino-5-oxo-1, 2, 4-oxadiazoline und aus N- Ethoxycarbonyl-N′-Heteroaryl-Thioharnstoffen oder N-Heteroaryl-N′-Hydroxyguanidin ...
