Abstract

magnified image An efficient three‐component one‐pot synthesis of medicinally important spirooxindoles is described by the reaction of isatin, malononitrile/ethyl cyanoacetate, and dimedone/barbituric acid using L‐proline as catalyst in ethanol at room temperature. This approach is convenient, mild, and affords the products in high yields without the use of chromatography. J. Heterocyclic Chem., (2010).
