In the second part of this research, one-pot and three-component synthesis of two
novel derivatives of fused quinolines were synthesized using condensation reaction
between aldehyde derivatives, 2-amino-1,4-naphthoquinone with three different
types of reagents including 4-hydroxycoumarin, 2-Hydroxy-1,4-naphthoquinone
and various derivatives of barbituric acid under reflux in ethanol and without any
catalyst with high efficiencies.
