ChemInform Abstract: Synthesis of the Functionalized Spiro[indoline-3,5′-pyrroline]-2,2′-diones via Three-Component Reactions of Arylamines, Acetylenedicarboxylates, and Isatins.

Depending on the molar ratios of the reactants, 3′-hydroxy or 3′-arylamino derivatives of the biologically important spiro systems are available. [ABSTRACT FROM AUTHOR]
