2‐(2‐Isocyanophenyl)‐1H‐indoles, a class of functionalized isocyanides containing both aromatic C−H and indolo N−H functionalities, are first applied in selective imidoylative annulation reactions. Scaffolds of 6‐aryl 11H‐indolo[3,2‐c]quinoline and 6‐aryl indolo[1,2‐c]quinazoline, both of which are of biological importance, are obtained selectively through capturing the imidoyl radical or imidoyl palladium
