General description

The interaction between 1-methylisatin and human adult haemoglobin was studied using the circular dichroism (CD) spectroscopic, anisotropy and FTIR investigations.

Application

  • Reactant for stereoselective preparation of spirobicyclic and bis-spirotricyclic pyrazolidinones
  • Reactant for regioselective preparation of spirocyclic oxindole-butenolides
  • Reactant for synthesis of spiro-oxindoles
  • Reactant for preparation of unsymmetrical oxindoles
  • Reactant for stereoselective preparation of hydroxyloxindoles via Morita-Baylis-Hillman reaction
  • Reactant for preparation of pyridinecarboxylic acid [(oxo)indolylidene)hydrazide derivatives (Schiff base hydrazides) as antibacterial agents
