CH Functionalization of Enamides: Synthesis of β‐Amidovinyl Sulfones via Visible‐Light Photoredox Catalysis

A mild, practical and environmentally friendly strategy to prepare β‐amidovinyl sulfones has been developed based on the sulfonation of enamides or enecarbamates via visible‐light photoredox catalysis. Direct CH functionalizations of enamides or enecarbamates under the optimized conditions proceeded with a wide scope of substrates and remarkable selectivity to give functionalized vinyl sulfones with good to excellent yields.
