Then, it is used one-pot three-components synthesis of spirooxindole derivatives via condensation of isatin, malononitrile, and 1,3-dicarbonyl compounds (1,3-cyclohexanedione) under mild reaction conditions in water as a green solvent. The present methodology offers several advantages, including ease of the preparation and handling of the catalyst, simple and easy work-up, short reaction times, high yields of the products and recyclability of the catalyst.          }, keywords = {ZnFe2O4,Multistep conversions,One-pot synthesis,Spirooxindole,Three-component}, url = {https://www.ajgreenchem.com/article_54160.html}, eprint = {https://www.ajgreenchem.com/article_54160_578ed2bb51b3a9d1ba466901fd1089b7.pdf} }
