Abstract

A one-pot method is proposed for the synthesis of 3-amino-2-arylquinolin-4(1H)-ones based on intermolecular cyclocondensation of isatoic anhydride and 1-(2-oxo-2-arylethyl)pyridinium salts in a basic medium followed by decomposition of pyridinium to amine by the action of hydrazine hydrate. The solutions of all the obtained amines emit in the blue-green region of the visible spectrum with a fluorescence quantum yield of up to 0.59 when irradiated with ultraviolet or violet light.
