beta-(2-Iodoanilino) esters undergo intramolecular alpha-arylation in the presence of Pd(PPh3)(4) and potassium phenoxide. The reaction is a useful methodology for the preparation of indole-3-carboxylic acid ester derivatives.

The factors that control the chemoselectivity of palladium‐catalyzedcyclization reactions of (2‐iodoanilino)carbonyl compounds have been explored by an extensive experimental computational (DFT) study. It was found that the selectivity of the process, that is, the formation of fused six‐ versus five‐membered rings, can be controlled by the proper selection of the initial reactant, reaction conditions
