  • Carotenoids and Related Polyenes, Part 12 First Total Synthesis and Absolute Configuration of 3'-Deoxycapsanthin and 3,4-Didehydroxy-3'-deoxycapsanthin
    作者:Yumiko Yamano、Mahankhali Venu Chary、Akimori Wada

    The synthesis of 3'-deoxycapsanthin (1) and 3,4-didehydroxy-3'-deoxycapsanthin (2), carotenoids of paprika, has been achieved by employing Lewis acid-promoted regio- and stereoselective rearrangement of the C(15)-epoxy dienal 5a. The absolute stereochemistry of the newly formed C-5 chiral center of rearrangement product 6a was determined to be (R) from its alternative synthesis derived from (+)-(R)-camphonanic

While the total synthesis of 1 has been previously reported in a poor overall yield, the total synthesis of the other seven stereoisomers of lutein has not yet been accomplished. We have developed a relatively straightforward methodology for the total synthesis of 1 and three of its stereoisomers, (3R,3′S,6′S)-lutein (2), (3R,3′S,6′R)-lutein or 3′-epilutein

    (3R,3′R,6′R)-Lutein and (3R,3′R)-zeaxanthin are two dietary carotenoids that are present in most fruits and vegetables commonly consumed in the US. These carotenoids accumulate in the human plasma, major organs, and ocular tissues. In the past decade, numerous epidemiological and experimental studies have shown that lutein and zeaxanthin play an important role in the prevention of age-related macular degeneration (AMD) that is the leading cause of blindness in the U.S. and Western World. The invention provides a process for the synthesis of (3R,3′R,6′R)-lutein and its stereoisomers from commercially available (rac)-α-ionone by a C 15 +C 10 +C 15 coupling strategy. In addition, the present invention also provides access to the precursors of optically active carotenoids with 3-hydroxy-ε-end group that are otherwise difficult to synthesize. The process developed for the synthesis of lutein and its stereoisomers is straightforward and has potential for commercialization.
    (3R,3′R,6′R)-叶黄素和(3R,3′R)-玉米黄质是两种膳食类胡萝卜素,广泛存在于美国常见的大多数水果和蔬菜中。这些类胡萝卜素在人类血浆、主要器官和眼部组织中积累。在过去的十年里,许多流行病学和实验研究表明,叶黄素和玉米黄质在预防年龄相关性黄斑变性(AMD)中起着重要作用,这是美国和西方世界导致失明的主要原因。本发明提供了一种从商业可获得的(rac)-α-离子酮通过C15+C10+C15偶联策略合成(3R,3′R,6′R)-叶黄素及其立体异构体的方法。此外,本发明还提供了一种获得具有3-羟基-ε-末端基团的光学活性类胡萝卜素前体的方法,否则这些类胡萝卜素前体很难合成。用于合成叶黄素及其立体异构体的方法是简单明了的,并具有商业化潜力。
