Abstract: The photochemical transformation of some 3-alkoxy-2-phenylchromones bearing various stabilizing substituents on the 3-alkoxy group have been described. In these studies, photoreactions occur through the 1,4-biradicals that yield angular tetracyclic products. The yield and distribution of the photoproducts are dictated by the nature of substituents of 3-alkoxy moieties.
