    摘要： The present invention provides an intermediate compound used for synthesis of polyene chain structure, that is an important moiety of carotenoid compounds, a process for preparing the same, and carotenoid polyene chain compounds prepared by using the intermediate, and, in particular, a process for preparing lycopene. The process for preparing the carotenoid polyene chain compound employs an allylic sulfone compound as starting material, which is reacted with C-5 sulfide compound to extend the carbon chain. The resultant thio-sulfone compound is oxidized, and the obtained disulfone compound is combined with C-10 di(haloallylic) sulfide compound to form a chain compound containing the desired number of carbon atoms. Then, the diallylic sulfone obtained by oxidation of the diallylic sulfide is subjected to Ramberg-Baklund reaction in order to form the central triene bond. After removal of sulfonyl groups, carotenoid polyene chain compound is obtained.

    摘要： New halogenated thioether compounds of the general formula R (SCH2-CHY-CH2X)n IN WHICH X represents a halogen atom, Y represents a hydrogen atom or a hydroxyl group, R is a mono or divalent cyclic or acyclic unsaturated hydrocarbon residue having up to 20 carbon atoms and n is 1 or 2 according to whether R is mono or divalent, are prepared by reacting thietane (thiacyclobutane or trimethylene sulphide) or 3-hydroxy thietane with a double-bonded halogen-substituted hydrocarbon derivative. By means of treatment with an aqueous solution of a base, the new thioether compounds in which Y is hydroxyl may be used to prepare corresponding new 2,3-epoxy-thiopropyl and bis(2,3-epoxy-thiopropyl) compounds.
