    • Abstract


      A new and convenient method for the synthesis of tamaraxetin uses hesperetin. By the action of iodine and silver acetate, it is converted into 3-acetoxy-hesperetin and eventually into 3-hydroxy-hesperetin which undergoes dehydrogenation by means of iodine and potassium acetate to yield tamaraxetin.

      5-Hydroxy-7-methoxy-flavanone (pinostrobin) is converted into alpinone by Fenton’s oxidation and subsequent dehydrogenation yields izalpinin.
