Title:
カロチノイドポリエン鎖化合物の製造方法及びそれを製造するための中間体
Document Type and Number:
Japanese Patent JP3975434
Kind Code:
B2
Abstract:
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.
