General description

Quantum chemical calculations of ground state energy, geometrical structure and vibrational wavenumbers of 1-acetylindole has been carried out using density functional (DFT/B3LYP) method. Regioselective acylations of 1-acetylindole (N-acetylindole) under Friedel-Crafts reaction has been reported. Reaction of 1-acetylindole with manganese(III) acetate in the presence of malonic acid, is reported to afford 4-acetyl-3,3a,4,8b-tetrahydro-2H-furo[3,2-b]indol-2-one.

Application

1-Acetylindole may be used in the stereocontrolled synthesis of (±)-geissoschizine. It may be used in the preparation of (1-acetyl-κO-indolyl-κC2)tetracarbonylmanganese, via a standard cyclomanganation procedure.
Reactant for preparation of:
  • Antimycobacterial agents
  • Cyclin-dependent kinase (CDK2) inhibitors

Reactant for:
  • C3-C3 oxidative cross-coupling reactions
