    • Abstract

       

      8-Hydroxy-galangin, the lowest member of the gossypetin series of flavonols, has been prepared and its properties and reactions compared with the other members. Its important derivatives are described. The tetramethyl ether has been obtained by two methods, one of which is the direct condensation of gossypetol-tetramethyl ether, obtained by the fission of herbacetin pentamethyl ether, with benzoic anhydride and sodium benzoate.
