  • Process for Synthesis of (3S)- and (3R)-3-Hydroxy-Beta-Ionone, and Their Transformation to Zeaxanthin and Beta-Cryptoxanthin

    (3R)-3-Hydroxy-β-ionone and (3S)-3-hydroxy-β-ionone are two important intermediates in the synthesis of carotenoids with β-end group such as lutein, zeaxanthin, β-cryptoxanthin, and their stereoisomers. Among the various stereoisomers of these carotenoids, only (3R,3′R,6′R)-lutein, (3R,3′R)-zeaxanthin, and (3R)-β-cryptoxanthin are present in commonly consumed fruits and vegetables. There are 3 possible stereoisomers for zeaxanthin, these are: dietary (3R,3′R)-zeaxanthin (1), non-dietary (3S,3′S)-zeaxanthin (2), and non-dietary (3R,3′S;meso)-zeaxanthin (3) which is a presumed metabolite of dietary lutein. Dietary lutein as well as 1 and 3 are accumulated in the human macula and have been implicated in the prevention of age-related macular degeneration. (3R)-β-Cryptoxanthin (4) is also present in selected ocular tissues at a very low concentration whereas its enantiomer (3S)-β-cryptoxanthin (5) is absent in foods and human plasma. The present invention relates to a process for the synthesis of (3R)-3-hydroxy-β-ionone and its (3S)-enantiomer in high optical purity from commercially available (rac)-α-ionone. The key intermediate for the synthesis of these hydroxyionones is 3-keto-α-ionone ketal that was prepared from (rac)-α-ionone after protection of this ketone as a 1,3-dioxolane. Reduction of 3-keto-α-ionone ketal followed by deprotection, lead to 3-hydroxy-α-ionone that was transformed into (rac)-3-hydroxy-β-ionone by base-catalyzed double bond isomerization in 46% overall yield from (rac)-α-ionone. The racemic mixture of these hydroxyionones was then resolved by enzyme-mediated acylation in 96% ee. (3R)-3-Hydroxy-β-ionone and its (3S)-enantiomer were respectively transformed to (3R)-3-hydroxy-(β-ionylideneethyl)triphenylphosphonium chloride [(3R)—C 15 -Wittig salt] and its (3S)-enantiomer [(3S)—C 15 -Wittig salt] according to known procedures. Double Wittig condensation of these Wittig salts with commercially available 2,5-dimethylocta-2,4,6-triene-1,8-dial provided all 3 stereoisomers of zeaxanthin (1-3). Similarly, (3R)—C 15 -Wittig and its (3S)-enantiomer were each coupled with β-apo-12′-carotenal to yield 4 and 5.
    (3R)-3-羟基-β-离子酮和(3S)-3-羟基-β-离子酮是合成带有β末端基团的类胡萝卜素如叶黄素、玉米黄质、β-隐黄素及其立体异构体的两个重要中间体。在这些类胡萝卜素的各种立体异构体中,只有(3R,3′R,6′R)-叶黄素、(3R,3′R)-玉米黄质和(3R)-β-隐黄素存在于常见的水果和蔬菜中。玉米黄质有3种可能的立体异构体,分别是:膳食(3R,3′R)-玉米黄质(1)、非膳食(3S,3′S)-玉米黄质(2)和非膳食(3R,3′S;meso)-玉米黄质(3),后者被认为是膳食叶黄素的代谢产物。膳食叶黄素以及1和3在人类黄斑中积累,并被认为有助于预防年龄相关性黄斑变性。 (3R)-β-隐黄素(4)也以极低浓度存在于选定的眼部组织中,而其对映异构体(3S)-β-隐黄素(5)在食物和人类血浆中不存在。本发明涉及一种从市售的(rac)-α-离子酮合成(3R)-3-羟基-β-离子酮及其(3S)对映体的高光学纯度的过程。合成这些羟基酮的关键中间体是从(rac)-α-离子酮制备的3-酮-α-离子酮缩酮,在保护该酮为1,3-二氧兰后得到。随后对3-酮-α-离子酮缩酮进行还原和去保护,得到3-羟基-α-离子酮,再经碱催化的双键异构化,从(rac)-α-离子酮中总产率为46%地转化为(rac)-3-羟基-β-离子酮。然后通过酶介导的酰化将这些羟基酮的外消旋混合物在96%纯度下分离。 (3R)-3-羟基-β-离子酮及其(3S)对映体分别按照已知程序转化为(3R)-3-羟基-(β-离子乙基)三苯基膦盐[(3R)—C15-Wittig盐]和其(3S)对映体[(3S)—C15-Wittig盐]。这些Wittig盐与市售的2,5-二甲基辛-2,4,6-三烯-1,8-二醛进行双Wittig缩合,提供了叶黄素的3种立体异构体(1-3)。类似地,(3R)—C15-Wittig及其(3S)对映体分别与β-脱氧-12'-类胡萝卜醛偶联,得到4和5。
