Reported herein is a visible-light-induced sulfonation of α-trifluoromethylstyrenes with sodium sulfinates, which provides a series of α-trifluoromethyl-β-sulfonyl tertiary alcohols. This new synthetic protocol is enabled by a charge-transfer complex between oxygen and sulfinates, featuring broad substrate scope and scalability. Excellent functional group compatibility and chemoselectivity render this method suitable for sulfonation of pharmaceutically relevant molecules. In the presence of D2O, deuteriotrifluorinated products were also obtained, further demonstrating the flexibility and synthetic potentials of this strategy.

Background: Peptic ulcer and urolithiasis are largely due to infection caused by urease-producing bacteria. Therefore, the discovery of urease inhibitors is an important area of medicinal chemistry research. Objective: The main aim of the work was to identify novel urease inhibitors with no cytotoxicity. Method: During the current study, a series of β-ketosulfones 1-26 was synthesized in two steps and evaluated for their in vitro urease inhibition potential. Results: Out of twenty-six compounds, seventeen have shown good to significant urease inhibitory activity with IC50 values ranging between 49.93-351.46 μM, in comparison to standard thiourea (IC50 = 21 ± 0.11 μM). Moreover, all compounds found to be non-cytotoxic against normal 3T3 cell line. Conclusion: This study has identified β-ketosulfones as novel and non-cytotoxic urease inhibitors.
