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

straightforward method for facileaccess to coumarin-fused dihydroquinolines (4) has been developed using the microwave-assisted multicomponent reactions of 4-hydroxycoumarin, aldehydes and aromatic amines in water catalyzed by bismuth triflate. Under solvent-free and conventional heating conditions, the same combination provided the corresponding coumarin-fused quinolines (5). An alternative and rapid
