1-Acetyl-3-indolinone was reacted with N-bis(methylthio)methylenebenzenesulfonamides in the presence of a base and it was found that the reaction differed accodring to reaction conditions. Reaction of 3-indolinone derivative (V, VII) with nucleophilic reagents such as amines and active methylenes afforded substitution products corresponding to the reagent used. By the use of these products, indole-condensed ring compounds, 1-(p-toluenesulfonylamino)-9-(p-toluenesulfonyloxy)pyrazino[1, 2-a]indole (IX) and 1-(p-toluenesulfonylamino)-3H-pyrrolo[1, 2-a]indol-3-one (XI), were synthesized.
