access various arylsulfur(VI) fluorides from commercially available aryl halides in a divergent fashion is presented. Firstly, a novel sulfenylation reaction with the electrophilic N‐(chlorothio)phthalimide (Cl‐S‐Phth) and arylzinc reagents afforded the corresponding Ar‐S‐Phth compounds. Subsequently, the S(II) atom was selectively oxidized to distinct fluorinated sulfur(VI) compounds under mild conditions
Compounds of Formula 1, or pharmaceutically acceptable salts thereof, are provided:
which are modulators of secreted frizzled related protein-1. The compounds, and compositions containing the compounds, can be used to treat a variety of disorders, including osteoporosis.

A practical electrochemical strategy for the direct synthesis of arenesulfonylfluorides from industrial feedstock nitroarenes is described. The key to success lies in using a cheap ionic liquid N-methylimidazolium p-toluenesulfonate ([Mim]TolSO3) as an effective additive and electrolyte to facilitate the selective reduction of nitroarenes to the corresponding aniline intermediate, promoting the desired

The synthesis and muscarinic binding properties of compounds based on the 1-[4-(4-arylsulfonyl)phenylmethyl]-4-(1aroyl-4-piperidinyl)-piperazine skeleton are described. For Compounds. substituted with appropriately configured methyl groups at the benzylic center and at the piperazine 2-position. high levels of selective, M-2 subtype affinity could be obtained. particularly when the terminal N-aroyl residue was ortho-substituted.
