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
