Zur Umsetzung von o‐funktionellen Benzylmalononitrilen mit N‐Bisnucleophilen sowie Alkoholaten

Abstract: O n the Reaction of o-Functional Benzylmalononitriles with N-Bisnucleophiles as well as Alcoholates Die o-funktionellen Benzylmalononitrile 1, 16 und 22 reagieren unterschiedlich gegeniiber N-Bisnucleophilen und Alkoholaten. 16 und 22 cyclisieren mit Guanidin nur zu den Pyrimidintriaminen 17 und 23, wahrend 1 durch DoppelringschluB direkt zu 4 reagiert. 1 setzt sich rnit Hydrazin bzw. Ethylendiamin zu den 2-Benzazepinen 7 bzw. 12 um. Beim Erhitzen von 22 rnit Na-methylat bzw. Na-ethylat wurden die 2-Benzazepin… Show more

“…Reaction of 37 with guanidine afforded the pyrimidinetriamine 38 which was cyclised to pyrimidobenzazepin 39 upon heating in acetic acid in the presence of trifluoroacetic acid (Scheme 14). 21 Furthermore, treatment of 37 with methanol or ethanol in the presence of the corresponding alkoxide afforded benzazepines 40. However yields are not available.…”
