Abstract The ionic liquid [H3N+CH2CH2OH][CH3COO-] (HEAA) catalyzes a three-component, one-pot condensation of malononitrile/ethyl cyanoacetate, 1,3-dicarbonyl compound/enol, and quinone or ninhydrin in water to afford a spiropyran derivative. This method has advantages of mild reaction conditions, short reaction time, and environmental friendliness.
