β-amino sulfones are important motifs found in
natural products
and active pharmaceutical compounds. Herein, we report a general and
highly regioselective intermolecular aminosulfonylation of alkenes
via the homolysis of sulfinyl oximes from ketoximes and sulfinyl
chloride. This method features catalyst-free, step-efficient functionalization
and prominent functional group tolerance, providing a straightforward,
green, and widely applicable approach to accessing β-amino sulfone
derivatives.
