An efficient synthesis of novelcoumarinderivativesvia a three‐component condensation of 4‐hydroxycoumarin, aldehydes and aromatic amines catalyzed by sulfonic acid functionalized ionic liquid L‐2‐(hydroxymethyl)‐1‐(4‐sulfobutyl)pyrrolidinium hydrogen sulfate ([HYSBPI]·HSO4) is reported. The condensed product was obtained with excellent yields in water under microwave irradiation condition. The antitumor
