title: Substitution and cyclization reactions involving the quasi-antiaromatic 2H-indol-2-one ring system.
abstract: The quasi-antiaromatic 2H-indol-2-one ring system is readily generated by treating a 3-hydroxy-substituted 1,3-dihydroindol-2-one with a Lewis acid. Stepwise addition of various pi-nucleophiles to the highly reactive 2H-indol-2-one system occurs smoothly to afford substituted oxindoles. The cyclization was also carried out in an intramolecular fashion to give spiro-substituted oxindoles in good yield.
