Rhodium-Catalyzed Highly Regio- and Enantioselective Hydrogenation of Tetrasubstituted Allenyl Sulfones: An Efficient Access to Chiral Allylic Sulfones

摘要

A highly regio- and enantioselective hydrogenation of challenging tetrasubstituted allenyl sulfones has been developed, affording chiral allylic sulfones in good yields with excellent regio- and enantioselectivities (up to 99% yield and 99% ee). This method provides an efficient and concise route to chiral allylic sulfones, thus offering an atom-economic process with a wide range of potential applications in organic synthesis and medicinal chemistry.
