Catalytic Hydrogenation of Carboxamides and Esters by Well-Defined Cp*Ru Complexes Bearing a Protic Amine Ligand
摘要:
A novel catalytic method for the straightforward hydrogenation of carboxamides and esters to primary alcohols has been developed. Chiral modification in the ligand sphere of the well-defined Cp*Ru catalyst molecule opens up a new possibility for the development of an enantioselective hydrogenation of racemic substrates via dynamic kinetic resolution.

eta(5)-C(5)(CH(3))(5)) with a suitably-designed PN ligand (PN = chelating tertiary phosphine-protic amine ligand) has been developed for a regioselective lactonization of unsymmetrically substituted 1,4-diols, which may provide an expeditious access to a variety of lactone lignans.
