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

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 me

Synthesis of thiophenes from allenyl sulfones involving α,β-unsaturated sulfines as intermediates

The synthesis of thiophenes starting from allenyl sulfones, via intermediate formation of α,β-unsaturated sulfines, is described.The allenyl sulfones were synthesized by a -sigmatropic rearrangement of appropriately substituted prop-2-ynyl sulfinates
