چکیده مقاله :
Modified zeolite (DEA-NAY) has been applied as an effective heterogeneous catalyst for one-pot synthesis of Tetrahydrobenzo[b]pyran via reaction of various isatins with malonitrile and dimedone in water at 1000C . The prepared catalysts were recovered and reused several times with minor reductions in activity. The high efficiency, short time and use of green solvent in mild conditions are the benefits of these methods (Scheme)
