Article abstract of DOI:10.1016/S0040-4039(00)60490-2

Cu(I)Cl-catalyzed oxidation of indole 1 by dioxygen in anhydrous acetonitrile leads to highly reactive 3-oxo 3H-indole 2, which provides directly 2-dialkylamino 3-oxo 3H-indoles 3 in presence of dialkylamines.Amidines 3, previously difficult to prepare, are potentially useful synthons in the field of heterocyclic chemistry. Key Words: Copper-catalyzed oxidation; dioxygen; indole; 2-dialkylamino 3-oxo 3H-indoles.
