Condensation of 5-arylethynyl-3-diethylaminonaphthoquinones with NH2NH2 afford 3-benzyl-9-diethylaminobenzo[de]cinnolin-7-ones. The substituents in the phenyl ring have a pronounced effect on the reaction time and the yields of benzocinnolinones and by-products. The replacement of the arylethynyl substituent in the starting naphthoquinone by the 3-hydroxyalk-1-ynyl group leads to a change in the direction of cyclization resulting in substituted naphtho[1,8-cd]-1,2-diazepin-8-ones as condensation products.
