چکیده
|
A facile, convenient, efficient and high-yielding synthesis of 3-aroylcoumarinoflavones has been developed by the condensation of easily synthesized 7-hydroxy-8-formylflavones and benzoyl acetonitriles in the presence of catalytic amount of l-proline in ethanol reflux. all the synthesized compounds were evaluated for their antioxidant activity. some of the compounds showed very good activity compared to standard bht.
