Melamine-formaldehyde resin supported H+:A mild and inexpensive reagent for synthesis of coumarins under mild conditions
摘要:
Melamine-formaldehyde resin supported H+ is used as an efficient catalyst in the Pechmann condensation reaction of phenols with β-ketoesters, in solvent-free media leading to the formation of coumarin derivatives using conventional heating and microwave irradiation in excellent yields with good purity.
