  Synthesis of fluoroalkyl methyl thioethers by formal addition of methanesulfenyl fluoride to alkenes

  摘要：

  The electrophilic anti-1,2-addition of the elements of methanesulfenyl fluoride to carbon-carbon double bonds by a one-pot reaction of dimethyl(methylthio)sulfonium tetrafluoroborate and triethylamine trishydrofluoride with various types of alkenes is used for the synthesis of beta-fluoroalkyl methyl thioethers. This reaction is stereospecific: starting from cis-cycloalkenes (1) trans-1-fluoro-2-(methylthio)cycloalkanes (2) are formed, while trans-cyclododecene (3) gives the cis product 4 everytime in good yields. With unsymmetrical alkenes these reactions proceed regioselectively to produce Markovnikov-oriented fluoro thioethers. With 2,6-norbornadiene (26) exclusive exo attack on one double bond and subsequent transannular participation of the second pi-bond gives rise to two isomeric 3,5-disubstituted nortricyclanes, 28 and 29, while starting from the medium-sized cis,cis-1,5-cyclooctadiene (10) no transannular pi-participation is observed: the trans-1,2-addition product to one of the two double bonds in 11 is isolated. In contrast, in the reaction of the monoepoxide 30 of this diene in addition to the simple 1,2-adduct 31 a transannular oxygen participation occurs producing three oxa bicyclic compounds 32-34. The oxidation of 1-fluoro-2-(methylthio)cyclooctane (2a) by sodium periodate yields the expected mixture of two diastereomeric 1-fluoro-2-(methylsulfinyl)cyclooctanes (36) which on pyrolysis give 3-fluorocyclooctene (37).

  The present invention relates to a method for capturing a molecular target present in the aqueous phase of a water-in-oil emulsion, said method being based on the use of a binding system comprising (a) a surfactant bearing a functional moiety on its hydrophilic head group and (b) a chemoprobe that acts as a molecular staple between the functionalized surfactant and the molecular target and comprises at least two distinct domains namely (i) at least one capture moiety which is able to specifically bind the molecular target and (ii) at least one binding domain which is able to interact with the functional group of the surfactant through covalent or non-covalent interactions, directly or through a binding intermediary.
