Electrochemical Sulfenylation of 4-Hydroxycoumarins with Aryl Thiols Catalyzed by Potassium Iodide

A KI-catalyzed indirect electrochemical oxidative method for the synthesis of sulfenylated 4-hydroxycoumarins via cross-coupling of 4-hydroxycoumarins and aryl thiols at a low potential has been reported. The electrocatalytic activity of KI for sulfenylat

HBr/H2O2-mediated formation of C–S bond with thiosulfates

A novel, efficient, and green protocol to construct C–S bond has been developed via HBr/H2O2-mediated sulfenylation of styrenes and 4-hydroxycoumarins leading to unsymmetrical sulfides. Various unsymmetrical sulfides were prepared in one step with moderate to good yields using environmentally-friendly H2O2 as oxidant and HBr as catalyst. Based on the preliminary experimental results, a plausible reaction mechanism was proposed for HBr/H2O2-mediated formation of C–S bond with thiosulfates.

Synthesis, antibacterial, and analgesic activity of novel 4-hydroxy-3-(phenylthio)-2H-chromen-2-ones and 4-Hydroxy-3-[imidazol/tetrazolo- 2-yl)thio]-2H-chromen-2-ones

A mild and efficient synthesis of new 4-hydroxy-3-(phenylthio)-2H-chromen- 2-ones 4a-k and 4-hydroxy-3-[imidazol/tetrazolo-2-yl)thio]-2H-chromen-2-ones 6a-d is described. The compounds 4a-c were further subjected to oxidation by m-CPBA to obtain 3-(phenylsulfonyl)-4-hydroxy-2H-chromen-2-ones 5a-c. The structures of the resulted new compounds were established by IR, 1H NMR, mass, and elemental analysis. All the synthesized compounds were subjected to antibacterial activity against the Gram positive bacteria Staphylococcus aureus, Bacillus subtilis, and Streptococcus haemolytius and the Gram negative bacteria Salmonella typhi, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumonia. The analgesic activity was carried out using Swiss albino male mice by abdominal concentration method. Supplemental materials are available for this article.
