A Pd(II)-catalyzed C(sp3)-H/C(sp2)-H coupling/annulation of anilides and α-dicarbonyl compounds for the synthesis of diverse N-acyl indoles is described. The reaction is achieved by cascade C-Hactivation, coupling, and intramolecular cyclization. This protocol provides a variety of indoles with high functional group tolerance and excellent regioselectivity. The utility of this protocol is demonstrated

A one-pot synthesis of indole derivatives from readily available acetanilides and diazo compounds was developed. This IrIII-catalyzed C–H alkylation and annulation reaction proceeds under mild conditions and generates molecular nitrogen and water as byproducts. Various types of synthetically versatile N-substituted indoles, including N-acetyl, N-pivolyl, and N-benzoyl indoles, were prepared.
