【 摘 要 】

A simple and efficient condition for Pechmann condensation for the synthesis of coumarins involving grinding of different phenols and β-ketoesters in the presence of p-toluenesulfonic acid at room temperature under solvent-free conditions has been described. A faster reaction and higher yields compared to the conventional methods are the advantages of present protocol.
