A ruthenium-catalyzedsynthesis of 2-methylindole was accomplished via a C–H allylation/oxidative cyclization cascade. Strategically, β-hydride elimination from the σ-alkyl-Ru intermediate has been suppressed by steric hindrance from a remote position. Hence, 2-methylindolines from the corresponding ortho-substituted anilines were achieved via protodemetalation in lieu of β-hydride elimination under
