An efficient palladium(II)-catalyzed aerobic dehydrogenation of saturated N-heterocycle-fused scaffolds was developed. This method provides aromatic N-heterocylces including indoles, quinolines, isoquinolines, and other 6-membered N-heterocycles in good to excellent yields without the need of alkoxides (for 48 examples, up to 99% yield).
