- 中文摘要: In order to study the relationship between structure and activity of flavones, several new 4'-phenylflavones, 4'phenylflavonols, and 4'-phenylflavanones are synthesized by cyclization of corresponding 4-phenyl-2'-hydroxychalcones with selenium dioxide in hot amyl alcohol, with hydrogen peroxide in cold alkalic ethanol, or with phosphoric acid in hot ethanol, respectively. the 4-phenyl-2'-hydroxychalcones are synthesized by condensation of p-phenylbenzaldehyde with various 2'-hydroxy-acetophenones in hot methanol under presence of potassium hydroxide.
