Asymmetric hydrogenations of phenylglyoxylate methyl ester and of acetophenone with catalytic amounts of iridium complexes containing hydrophilic chiral C 2 -symmetric diamine ligands is reported. E.e. values of up to 68% are observed for complete acetophenone hydrogenation in hydrophilic media. The use of such ligands allowed catalyst recovery without loss of activity and enantioselectivity...
