Abstract
A heterogeneous Au/TiO2 catalyzed stereoselective hydrogenation of ynamides provides Z-enamides in a highly stereoselective manner in the presence of inexpensive ammonium formate as the hydrogen source. The commercially available gold nanoparticle catalyst could be recycled multiple times without a significant loss of activity.
