Synthesis of multisubstituted arylsulfones via a one-pot, three-component [3 + 3] benzannulation reaction

Abstract

A one-pot, three-component [3 + 3] benzannulation reaction of α,β-unsaturated carbonyl compounds, bromoallylic sulfones, and sodium sulfinates had been developed. A series of multisubstituted arylsulfones were prepared with moderate to good yields. This method has the advantages of good step-economy, broad substrate scope and operational simplicity.
