A simple, efficient, and green, one-pot four-component synthesis of spiro[indoline-3,4′-quinoline] derivatives has been developed from isatin, ethyl cyanoacetate/malononitrile, dimedone, and aniline using green catalyst DABCO and green solvent ethanol. The current method generates good to exceptional yields in a short reaction time and provides a broad substrate scope. This method also works for gram-scale

Lastly, this catalyst managed to afford an unprecedented product that was derived using an innovative technique—a combination of multicomponent reactions. Essentially, the product of our previously reported aza-Friedel–Crafts multicomponent reaction could itself be used as a reactant instead of aniline in the synthesis of more complex dihydropyridines.

A simple and efficient synthesis of spiro[indoline-3,4'-quinoline] derivatives by a one-pot reaction of isatin, malononitrile, and enaminone under microwave irradiation was investigated. This protocol has the advantages of short reaction time, high yields of products, broad substrate scope, and easy workup procedure.

efficient one-potsynthesis of biologically interesting spirooxindole derivatives bearing hexahydroquinoline skeleton was accomplished by EDDA-catalyzed, three-component reactions between isatins, malononitrile, and enaminones in good yields. The value of this methodology lies in its inexpensive and nontoxic organocatalyst, mild reaction conditions, and ease of handling. A simple and efficient one-pot synthesis
