Biscoumarin analogs were synthesized by the reaction between two equivalent of 4‐hydroxycoumarin and one equivalent of aryl aldehydes induced by visible light [22 W compact fluorescent lamp (CFL) bulb]. This new method is simple, cost‐effective, and furnished excellent yields with broad substrate generality in short reaction time.
