The 8-iodo flavones formed by cyclization of benzyl-protected chalcones with iodine in dimethyl sulfoxide have been transformed by a Suzuki coupling reaction into a variety of 8-aryl derivatives. Deprotection with boron tribromide has generated a family of new 8-aryl flavones containing four to eight hydroxyl groups.
