2-Hydroxyl/acetoxy-3-nitroindoles are directly and efficiently prepared in good to excellent yields from diazo(nitro)acetanilides under the catalysis of Cu(MeCN)4PF6 DCM through an intramolecular aromatic C-H insertion or followed by acetylation. 2-Hydroxyl-3-nitroindoles can be further transformed 3-halo-3-nitroindolin-2-ones 3-alkanamidoindolin-2-ones readily. All them important synthetic building blocks for construction indole derivatives.
