Crich, David published the artcileCyclofunctionalization of unsaturated alcohols, phenols, acids, and sulfonamides with 1-benzenesulfinyl piperidine and trifluoromethanesulfonic anhydride, HPLC of Formula: 4972-31-0, the publication is Heterocycles (2004), 827-830, database is CAplus.
The combination of a benzenesulfinamide, trifluoromethanesulfonic anhydride, and Huenig’s base brings about the cyclofunctionalization of unsaturated alcs., phenols, acids, and sulfonamides to give the corresponding α-phenylsulfanylmethyl cyclic ethers, lactones and sulfonamides, resp. In an unanticipated twist the products are isolated at the sulfur (II) oxidation state denoting an overall reduction in the oxidation state of the sulfur based electrophile in the course of the reaction.
