Abstract: A green and efficient protocol was developed for the one-pot three-component synthesis of
novel 2-(4-hydroxy-2-oxo-2H-chromen-3-yl)-2-(arylamino)-1H-indene-1,3(2H)-dione derivatives by
the reaction of 4-hydroxycoumarin, ninhydrin and aromatic amines in the presence of guanidine hydrochloride
as an organocatalyst under solvent-free conditions. The present approach offers several advantages
such as low cost, simple work-up, short reaction times, chromatography-free purification,
high yields and greener conditions.
