In the presence of p-toluenesulfonic acid as the catalyst the three-componentreactions of arylamines, acetylenedicarboxylates, and isatins showed very interesting moleculardiversity. When equal amount of arylamine was used, the three-componentreaction resulted in the high yields of functionalized 3′-hydroxyspiro[indoline-3,5′-pyrroline]-2,2′-dione derivatives. On the other hand the functionalized
