    • Abstract


      Starting from 2-hydroxy-3: 6-dimethoxy acetophenone a new synthesis of 3-hydroxy primetin has been effected and by alkali fission of the trimethyl ether 2-hydroxy-ω: 3: 6-trimethoxy acetophenone has been prepared. Using the same procedure (modified Kostanecki’s method) 3:5:8:3′: 4′-pentahydroxy flavone, its pentamethyl ether and penta-acetate have been obtained. The properties of these compounds are different from those of the pentahydroxy flavone and its derivatives obtained from Ponderosa Pine Bark.
