Asymmetric Hydrogenation of Azaindoles: Chemo‐ and Enantioselective Reduction of Fused Aromatic Ring Systems Consisting of Two Heteroarenes
by using the chiral catalyst, which was prepared from [Ru(η3‐methallyl)2(cod)] and a trans‐chelating bis(phosphine) ligand (PhTRAP). The dearomative reaction exclusively occurred on the five‐membered ring, thus giving the corresponding azaindolines with up to 97:3 enantiomer ratio.
