Description
Summary:A simple, efficient, and eco-friendly procedure for the synthesis of 2-quinolinyl chromones via oxidative cyclization of 2-hydroxyquinolinyl chalcones by grinding with ammonium iodide at room temperature under solvent-free conditions has been described. The protocol is very efficient as the reactions are carried out at room temperature with high yields and avoid the use of hazardous chemicals and organic solvents at any stage of the reaction.
