摘要：

Silica bonded N-propyl sulfamic acid (SBNPSA) is employed as a solid acid catalyst for the synthesis of spirooxindoles via three-component reaction in good yields and short reaction times in ethanol under irradiation micrwave conditions. Irradiation of the combination of isatin or acenaphthoquinone, an activated methylene reagent, and 1,3-dicarbonyl compounds in the presence of catalytic (SBNPSA) was found to be a suitable and efficient method for the synthesis of the biologically important spirooxindoles.
