A copper-catalyzed, ligand-free intramolecular C-N coupling method has been developed for the synthesis of (E)-3-arylideneindolin-2-ones, which are biologically important compounds. This approach offers efficient and practical synthetic route with readily available starting materials and high efficiency.
A copper-catalyzed, ligand-free intramolecular C-N coupling of (E)-2-(2-bromophenyl)-3-arylacrylamides has been developed. This protocol provides an efficient and practical synthetic route for the biologically important (E)-3-arylideneindolin-2-ones from o-bromophenylacetic acids and aromatic or conjugated alkenyl aldehydes. Readily available starting materials, mild and noble metal-free conditions, high efficiency, and good tolerability for phenolic hydroxyl groups make this approach attractive and applicable.
