New compounds of N-(substituted thio) isatins (III) were synthesized and reactions with several nucleophiles were examined in comparison with the reaction using N-(substituted thio) phthalimides (I) and N-(substituted thio) succinimides (II) : All of I, II, and III reacted with organometallic compounds, cyanide ion, and trichloromethyl carbanion to give sulfides (IV), thiocyanates (V), and trichloromethyl sulfides (VI) respectively. Different from I and II, however, the reaction of III with amines afforded 3-amino-1-substituted thio-3-hydroxy-2-oxo-indoles (X), with no formation of any sulfenamides anticipated.
