Palladium-catalyzed synthesis of indoles via intramolecular Heck reaction

• Synthesis of indoles
• Intramolecular Heck reaction
• Readily available P(OPh)3 as the ligand
• Cyclization

Highly effective Pd-catalyzed synthesis of indoles from 2-halo-anilines and allyl bromides via intramolecular Heck reaction in the presence of P(OPh)3 as the ligand is described.
