Abstract

Cyano functionalized 6-methoxyquinolin-2-ones were synthesized from malonic acid derivatives and p-anisidines in multistep reactions via 4-chloro-6-methoxyquinolin-2-ones. Introduction of cyano substituents resulted in 3,4-dicyano-6-methoxyquinolin-2-ones or 4- cyano-6-methoxyquinolin-2-ones, depending on the substituents in position 3 and 1. The study of the fluorescence properties of 3,4-dicyano-6-methoxyquinolone showed emission values up to 550 nm (black curve) combined with large Stoke\'s shifts , whereas 4-cyano-6- methoxyquinolones gave lower values (e.g. blue curve) comparable to earlier findings.
