A versatile one-pot synthesis of substituted isoindolinones from 2-furaldehydes, amines, 2-(phenylselanyl)acrylic acids, and isocyanides is described. The tandem process involves the Ugi four-component condensation, intramolecular Diels−Alder cycloaddition, and subsequent deselenization−aromatization promoted by BF3−OEt2. The procedure is general and efficient and the substrates are easily available.
