- W1997414717 abstract "Die Titelverbindung 1 wird mit Diazonium-Salzen zu den 5-Arylazo-Verbindungen 8 umgesetzt, mit aromatischen Aldehyden zu den 5-Aryliden-Derivaten 10 und mit p-Nitroso-dimethylanilin zum 5-Azomethin 13, das zum o-Chinon 14 hydrolysiert wird. Die 5-Benzyliden-Verbindung 10a wird zum 5-Benzyl-Derivat 11 reduziert. Der Pyridin-Ring in 1 wird durch Umsetzung mit Phenylhydrazin und Benzylamin geöffnet. Das linear anellierte Analogon 2 von 1 ergibt mit Diazonium-Salzen die 6-Arylazo-Verbindungen 17. Reactions with Benzimidazo[2,1 -a]isoquinoline-6(5 H)-one The title compound 1 couples with diazonium salts to give 5-arylazo derivatives 7, condenses with aromatic aldehydes to give 5-arylidene derivatives 10 and with p-nitrosodimethylaniline to give the 5-azomethine derivative 13 which is hydrolysed to the o-quinone 14. The 5-benzylidene compound 10a is reduced to the 5-benzyl derivative 11. The pyridine ring in 1 has been opened by the action of phenylhydrazine and benzylamine. The linear analogue 2 of 1 has been coupled with diazonium salts to give 6-arylazo derivatives 17." @default.
