A solvent-free synthesis of coumarins using a Wells-Dawson heteropolyacid as catalyst
Seventeen examples are resolved, most of them in good to excellent yields, using the cheap WD catalyst. Substituted coumarins are synthesized from phenols and β-ketoesters by the Pechmann reaction, using a Wells-Dawson heteropolyacid (H 6P 2W 18O 62• 24H 2O) as catalyst by a solvent-free procedure....
