DMAP-catalyzed cascade reaction: one-pot synthesis of benzofurans in water

A series of benzofurans were efficiently synthesized in good to excellent yields using 4-dimethylaminopyridine (DMAP) catalyzed cascade reaction between salicylaldehydes and halogenated ketones in water at 80 °C opened atmosphere.
