    • Abstract


      3-Methoxy-7-hydroxy flavone does not undergo nuclear methylation. Nuclear methylation of (1) 3-O-methyl galangin and (2) 3:4′-O-dimethyl kaempferol has been shown to take place in the 6-position. As an intermediate in the case of (1) 3-O-methyl-6-C-methyl galangin has been isolated. The minimum structural requirements of this reaction and its mechanism are discussed.
