Abstract
7-Hydroxy-3-carboxycoumarin is prepared by a one-pot consecutive process, carried out in water, starting from 2,4-dihydroxybenzaldehyde and malononitrile. The procedure highlights the advantages of using an aqueous medium, particularly the possibility of controlling the pH and isolating the reaction product without using any organic solvent.
