An efficient one-pot protocol for the synthesis of 2-((substituted amino)(4-phenyl)methyl)-3-hydroxy-naphthalene-1,4-dione derivatives has been developed by the three-component reaction of 2-hydroxy-naphthalene-1,4-dione, aromatic aldehydes and anilines/heterocyclic amines using montmorillonite K-10 as a catalyst. The advantages of this method include short reaction time, excellent yield and easy work-up.

An efficient one-pot synthesis of fluorescent hydroxyl naphthalene-1,4- dione derivatives by a simple, atom-economical and three-component reaction of 2- hydroxynaphthalene-1,4-dione, aromatic aldehydes and heterocyclic or carbocyclic amines in the presence of a catalytic amount of InCl3 in refluxing water is reported. The structures of the compounds were confirmed by IR, 1H NMR, 13C NMR, and elemental analysis. UV- visible absorption coefficient, maximum wavelength and fluorescence emission wavelength were measured in methanol. The products were fluorescent in solution emitting at green light (546-560 nm). The advantages of this procedure are mild reaction conditions, high yields of products, operational simplicity and easy work-up procedures. The workup of these very clean reactions involves only a filtration and simple washing step with EtOH.
