Electrochemical Carboxylation of Flavones: Facile Synthesis of Flavanone-2-carboxylic Acids

Electrochemical Carboxylation of Flavones: Facile Synthesis of Flavanone-2-carboxylic Acids

Constant current electrolysis of flavones in DMF containing 0.1 mol dm-3 Bu4NBF4 in the presence of CO2 by using a one-compartment cell equipped with a Pt cathode and an Mg anode resulted in reductive carboxylation at the C2 position of flavones in a highly regioselective manner to give flavanone-2-...

Zusammenfassung:Constant current electrolysis of flavones in DMF containing 0.1 mol dm-3 Bu4NBF4 in the presence of CO2 by using a one-compartment cell equipped with a Pt cathode and an Mg anode resulted in reductive carboxylation at the C2 position of flavones in a highly regioselective manner to give flavanone-2-carboxylic acids in moderate to good yields.
