Abstract
5-Aminobenzotriazole and its derivatives are good substrates for reactions with beta-diketones and 3-buten-2-one to produce angular triazolo[4,5-f]qui nolines. Interesting isomeric compounds were found in the case of reaction with non-symmetrical diketones, whereas an unusual cyclization takes place when 2-acetylcyclopentanone was used.
