摘要：

An efficient and novel green catalytic protocol for the synthesis of biologically important spirooxindole derivatives is developed in a one-pot, three-component approach involving substituted isatin, activated methylene reagent, and 3-methyl-1-phenyl-2-pyrazolin-5-one in water under sonication. This report describes the use of sodium chloride as a nonacidic and green catalyst for a variety of substrates. The advantageous features of this methodology are the environmentally benign character, operational simplicity, high yield processing, easy handling, and the fact that the products do not need to be purified.
