چکیده
|
Wells–dawson tungsten heteropolyacid (h6p2w18o62) has been applied as an effective heterogeneous catalyst for one-pot synthesis of spiro[4h-pyran-3,3’-oxindoles] via reaction of various isatins, malonitrile and 1,3-dicarbonyl compound in water. the corresponding products were obtained in high yields. the catalysts were easily recycled and reused without loss of their catalytic activity.
