Abstract
Syntheses of some new pyridotriazolo- and pyridotetrazolopyrimidines are described. These tricyclic systems and tetrazoloquinazoline react with some carbon nucleophiles, generated from compounds with reactive methylene groups, exclusively at position 2 of the fused pyrimidine ring to give the corresponding open-chain enamines.
Zusammenfassung
Die Synthesen von einigen neuen Pyridotriazolo- und Pyridotetrazolopyrimidine werden beschrieben. Diese tricyclischen Verbindungen sowie Tetrazolochinazolin reagieren mit einigen Carbanionen, die aus Verbindungen mit reaktiven Methylengruppen entstehen, ausschließlich in Stellung 2 des kondensierten Pyrimidinringes, wobei die entsprechenden offenkettige Enamine entstehen.
