Reductive amination under hydrogen pressure is a valuable process in organic chemistry to access amine derivatives from aldehydes or ketones. Knölker's complex has been shown to be an efficient iron catalyst in this reaction. To determine the influe

International audience; A twelve-step synthesis of (-)-(R)-sumanirole starting from quinoline is described. The first synthetic approach, using a chiral Reissert adduct, was too problematic to be pursued further. In the second successful approach, th
