(S,S)-Quinine thiourea derivatives were used for the three component asymmetric Knoevenagel/Michael/cycli- zation cascade reaction of different isatin, maleimide, and malononitrile in organic catalysis. Under the optimal catalyst conditions, chiral spiro(indoline-3,4-pyrrolo[3,4-b]pyridine) was obtained with a chemical yield of 75% to 86% and a maximum enantioselectivity of 92% ee. This study has expanded the range of catalyst types and substrates for this reaction.

Key words: organocatalysis, enantioselective synthesis, Knoevenagel/Michael/cyclization, spiro[indoline-3,4-pyrrolo[3,4- b]pyridine]
