Photosensitized 1,2-Sulfonylamination of Alkenes With Sulfonylamide

Herein, we developed a metal-free, photosensitized strategy for difunctionalization of olefin feedstocks to access β-amino sulphone architectures, enabled by a tailor-made, readily accessible sulfonylamide bifunctional reagent. This protocol could accommodate a wide range of alkenes and a variety of sulfonylamides, with high yields and excellent regioselectivity. Given remarkably mild reaction conditions, readily accessible starting materials, excellent functional group tolerance, and well-defined regioselectivity, this approach would enable an efficient platform for the assembly of densely functionalized molecular scaffolds.
