Flavanones are important precursors for synthesis of Flavones, isoflavones, flavonols and dihydroflavonols. The flavone skeleton is present in a wide range of synthetic and naturally occurring products exhibiting various interesting pharmacological activities. The cyclization of 2' hydroxyl acetophenone and 2'-hydroxychalcone in presence of methane sulphonic acid, triethylamine and hydrogen peroxide type of catalyst in presence of mild base with suitable solvent like ethanol, acetic acid, DMF or DMSO. Procedure with improved yields for the preparation of flavone, flavanones and isoflavanones.
