ORANGE TO BROWNISH CRYSTALLINE POWDER
[Uses]

  • 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
