An efficient synthesis of N-fused polycyclic indoles by a palladium-catalyzed annulation/acyl migration cascade reaction is described. The reaction is ligand-free, scalable, and provides access to a diverse range of useful indole scaffolds from readily available starting materials. Supporting mechanistic studies indicate that the reaction likely proceeds via an intramolecular α-arylation mechanism. The synthetic utility of this protocol is demonstrated by a gram-scale reaction and syntheses toward indole alkaloids and a HSP90 inhibitor.

Dirhodium(II)-carboxylate complexes were discovered to promote the selective migration of acyl groups in trisubstituted styryl azides to form 1,2,3-trisubstituted indoles. The styryl azides are readily available in three steps from cyclobutanone and 2-iod
