β-Amido sulfone motif reprents a particularly useful scaffold for the biologically active molecules. The hydrogenation ofβ-amidovinyl sulfon is an alternative method to synthesizeβ-amido sulfone. Herein, one electrochemical method to synthesizeβ-amido sulfone using sodium sulfites and tertiary amines as substrates is presented. OnlyE-configurations ofβ-amidovinyl sulfonyl were synthesized under metal catalyst- and oxidant-free condition. Cyclic voltammetry (CV) and control experiments indicate that this electrosynthesis reaction goes through a radical process which the sulfonyl radical adds to enamine to form the carbon radical.

Key words: β-amido sulfone, β-amidovinyl sulfon, sodium sulfites, tertiary amines
