In the past decade asymmetric hydrogenation reactions of various heteroaro-matic compounds including quinoxaline, pyridine, indole, pyrrole, and furan have been achieved. In 2003 the authors reported the use of [Ir(cod)Cl]2MeO-BiPhep/I2 for enantioselective hydrogenations of quinoline derivatives (J. Am. Chem. Soc. 2003, 125, 10536). In the current report the authors disclose a full account of the generality of this method with a variety of functionalized quinolines.
