Abstract

An efficient and straightforward three-component reaction of enamides, aryldiazonium tetrafluoroborates, and 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) (DABSO) for the direct C(sp²)-H arylsulfonylation of enamides has been developed. This Cu(OTf)₂-mediated SO₂ insertion reaction proceeds smoothly to afford a diverse range of β-amidovinyl sulfones bearing manifold functional groups in moderate to excellent yields with high regio- and stereoselectivities.
