A highly enantioselective synthesis of indolines by asymmetric hydrogenation of 1 H ‐indoles and 3 H ‐indoles at ambient temperature and pressure, catalyzed by chiral phosphine‐free cationic ruthenium complexes, has been developed. Excellent enantio‐ and diastereoselectivities (up to >99 % ee , >20:1 d.r.) were obtained for a wide range of indole derivatives, including unprotected 2‐substituted and 2,3‐disubstituted 1 H ‐indoles, as well as 2‐alkyl‐ and 2‐aryl‐substituted 3 H ‐indoles.
