Synthesis of Indole-3-carboxylic Acid Derivatives by Pd(0)-Catalyzed Intramolecular α-Arylation of β-(2-Iodoanilino) Esters
摘要:
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.

Samariumdiiodide (SmI2) mediated reductive coupling reactions are powerful methods for the construction of carbon–carbon bond in organic synthesis. Despite the extensive development in recent decades, successful examples of the corresponding asymmetric reactions remained scarce, probably due to the involvement of highly reactive radical intermediates. In this Article, we report an enantioselective
