VerwendenEthynyl p-tolyl sulfone (Tosylacetylene) may be used in the synthesis of 2-(4-methylphenylsulfonyl)ethenyl (tosvinyl, Tsv) protected derivatives. It may be used as starting reagent for the synthesis of optically active indan-2-ols.
synthetischeEthynyl p-Tolyl Sulfone has been prepared by several groups over the years employing a variety of synthetic strategies including ethynyl Grignard addition to p-toluenesulfonyl fluoride, dehydroiodination of (E)-2-iodo-1- tosyl-1-ethene, oxidative elimination of β-[(4-methylphenyl)seleno]vinyl sulfone, dehydrobromination of cis-and trans-2-bromovinyl 4-methylphenyl sulfone,23 diazotization of 4-[(4-methylphenyl)sulfonyl]-5- aminoisoxazole, and oxidation of ethynyl thioether. The modified strategy commonly used today is an established Friedel-Crafts based procedure first performed by Bhattacharya et al. but recently exploited by Waykole and Paquette (eq 1). Its simplicity and mildness has shown it to be broadly useful since it bypasses the need for immoderate conditions encountered in the earlier strategies.
