A new strategy involving three-component functionalization of olefins with sulfoxyimidoylsulfonium salt and a nucleophilic reagent for the synthesis of β-amino alcohols and β-amino ethers by photoredox catalysis was developed. The sulfoxyimidoylsulfonium salt is important and serves as the N-centred radical precursor. β-Amino alcohols and β-amino ethers bearing various functional groups are synthesized in good yields under mild conditions. Furthermore, the advantages of this strategy are greater safety, no additives, and easy to obtain raw materials.
