Photocatalytic selective synthesis of ()-β-aminovinyl sulfones and ()-β-amidovinyl sulfones using Ru(bpy)Cl as the catalyst.

Selectively producing a variety of valuable compounds using controlled chemical reactions starting from a common material is an appealing yet complex concept. Herein, a photocatalytic approach for the selective synthesis of ()-β-aminovinyl sulfones and ()-β-amidovinyl sulfones from allenamides and sodium sulfinates was established. This reaction exhibits the traits of an eco-friendly solvent and adjustable amide cleavage, and can accommodate a diverse range of substrates with exceptional functional group tolerance. Based on control experiments and deuterium labeling experiments, a plausible radical reaction pathway is proposed.
