专利号:US-7247752-B2 优先权日:2004-10-01 标 题 :Methods for the synthesis of astaxanthin 发明人:LOCKWOOD SAMUEL F; TANG PENG CHO; NADOLSKI GEOFF; JACKSON HENRY L; FANG ZHIQIANG; DU YISHU; YANG MIN; GEISS WILLIAM; WILLIAMS RICHARD; BURDICK DAVID 权利人:CARDAX PHARMACEUTICALS INC 摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.
