| Abstract: | The synthetic methods of the intermediates of the substituted flavone 8 acetic acids were studied. The syntheses were carried out via acylating, Fries rearrangement, chloromethylating, cyanating, condensation and oxidization. By the new method, new compounds such as 2′ hydroxyl 3′ cyanomethyl 5′ methyl 4 bromo chalcone and 4′|bromo 6 methyl 8 cyanomethyl flavone were synthesized. This method is characterized by the short reaction time, the simple operation and the good yieid. |
