  • Title: Iridium-monodentate phosphoramidite-catalyzed asymmetric hydrogenation of substituted benzophenone N-H imines.
    Author: Hou G, Tao R, Sun Y, Zhang X, Gosselin F.
    Journal: J Am Chem Soc; 2010 Feb 24; 132(7):2124-5. PubMed ID: 20104899.
    Abstract:
    Homogeneous asymmetric hydrogenation of unprotected benzophenone N-H imines 1a-r using Ir-(S)-N-benzyl-N-methyl-MonoPhos as a catalyst provides chiral amines 2a-r in 80-96% yield with enantioselectivities up to 98% ee (18 examples) for ortho-substituted substrates.
