Oxy-sulfonylation of terminal alkynesviaC-S coupling enabled by copper photoredox catalysis

We report the first literature example using visible light-induced trimethylsilyl azide (TMS-N3)-assisted copper-catalyzed oxy-sulfonylation of terminal C-C bonds to form β-keto sulfones (C-S bond formation). TMS-N3promotes the reaction by facilitating the formation of sulfonyl radicals, which later decompose into N2gas upon light irradiation. This method involves the use of commercially available and stable starting materials. Also, a wide range of functional groups have been well-tolerated under the current photoredox process, evading the side product formation. Potent biologically active compounds, such as CES1, 11β-HSD1 inhibitors, anti-analgesic agents, and reactive synthesis intermediates were synthesized to demonstrate the synthetic utility of the current methodology. Moreover, green chemistry metrics and Eco-scale evaluation for the current photochemical method show that the protocol is eco-friendly and highly efficient.

Cu(OTf)2-Catalyzed efficient sulfonylation of vinyl azides with sodium sulfinates

A simple oxidative cross-coupling reaction between vinyl azides and sodium sulfinates was developed. This reaction uses commercial arylsulfinates that are more efficient, cheaper, and more stable as sulfonylation reagents, for efficiently, cheaply, and environmentally friendly synthesis of β-keto sulfones. And the reaction has the advantages of simple operation, high efficiency, good yield, and also has a wide range of functional group tolerance.

Copper-catalyzed aerobic oxidative cross-coupling reactions of vinylarenes with sulfinate salts: A direct approach to β-ketosulfones

A copper-catalyzed aerobic oxidative cross-coupling reactions for the synthesis of β-ketosulfones via formation of a C[sbnd]S bond has been demonstrated. Promoted by the crucial copper catalyst, perfect selectivity and good to excellent yields could be achieved. This method, including inexpensive copper catalyst, wide functional group tolerance, and open air conditions, make it very attractive and practical. More importantly, it also provides a versatile tool for the construction of β-ketosulfones from basic starting materials under mild conditions.
