Herein, we report a synthesis of medicinally relevant β-ketosulfonamides via a photomediated 1,3-rearrangement of alkenyl sulfamates. This protocol tolerates a wide array of sensitive functional groups including alkenes, alkynes, and nitrogen-based heterocycles. Additionally, this work provides a general approach toward alkenyl sulfamates via a two-step Sulfur(VI) Fluoride Exchange (SuFEx) sequence capitalizing on SO2F2 as a linchpin to efficiently couple readily available ketones and amines without a large excess of either partner.

Highly enantioselective transfer hydrogenation of β-keto sulfonamides was developed via dynamic kinetic resolution using a chiral Ru(ii) catalyst with an azeotropic solution of HCO2H/Et3N as a hydrogen donor, affording α-substituted β-hydroxyl sulfonamides in good yields with excellent diastereo- and enantioselectivities. This method is featured with mild conditions, easy operation, and a broad substrate scope, which make it possible to find wide applications in the synthesis of natural products and biologically active compounds containing the α-substituted β-hydroxyl sulfonamide core.
