Abstract: A photo-reorganization of 3-alkoxy-2-(alkoxyphenyl)chromones to the isomeric angular tetracyclic compounds through the 1,4-biradical generated by the excited carbonyl group through the γ-hydrogen abstraction has been described. Substituent effect of the 3-alkoxy group and the effect of position of alkoxy group in the 2-phenyl ring are explained.
