  A Convenient Synthesis of the Echinacea-Derived Immunostimulator and HIV-1 Integrase Inhibitor (−)-(2R,3R)-Chicoric Acid

  摘要：

  The Echinacea-derived immunostimulator and HIV-1 integrase inhibitor (-)-chicoric acid (=2,3-bis([3(3,4-dihydroxyphenyl)-1-oxoprop-2-enyl]oxy)butanedioic acid; 1a) was conveniently prepared via a silane-promoted Pd-mediated chemoselective hydrogenolysis of its perbenzylated derivative 12a, which was generated from an efficient and reliable carbodiimide-mediated coupling reaction between the caffeic acid dibenzyl ether derivative 7 and commercially available (+)-dibenzyl L-tartrate (9a). The other naturally occurring dextrorotatory chicoric acid (1b) can be similarly prepared.

  recent years. Among these foods, cocoa and dark chocolate are particularly rich in procyanidins, one of the major dietary families of polyphenols. We developed the first asymmetric total synthesis of procyanidin B2 and applied it to the preparation of a regioselectively radiolabeled 14C-analogue, which will be used to strengthen our knowledge on the metabolism of procyanidins.(© Wiley-VCH Verlag GmbH & Co

  近年来，为了纯粹的愉悦而消费的食物可以提供健康益处的想法得到了很多认可。在这些食物中，可可和黑巧克力富含原花青素，这是多酚的主要膳食家族之一。我们开发了第一个原花青素 B2 的不对称全合成，并将其应用于制备区域选择性放射性标记的 14C 类似物，这将用于加强我们对原花青素代谢的了解。（© Wiley-VCH Verlag GmbH & Co. KGaA， 69451 魏因海姆，德国，2008）

  debenzylation of cinnamic amides 45–49 with the anilino moiety provided our desired cinnamic amides 6–10 without inducing the intramolecular Michael addition. Debenzylation of cinnamic amides 43, 48, and 53 with a 2,4-dibenzyloxyphenyl group was also successfully accomplished using BBr3 to give 4, 9, and 14. Among the nine compounds that inhibited mushroom tyrosinase more potently at 25 μM than kojic acid, four

  在调节黑色素生物合成的三种酶，酪氨酸酶及其相关蛋白TYRP-1和TYRP-2中，酪氨酸酶是最重要的，因为它能够限制黑色素细胞中黑色素的产生速率。对于治疗由黑色素过量引起的皮肤色素沉着症，酪氨酸酶的抑制是迄今为止最成熟的策略。肉桂酸是一种安全的天然产物，具有（E）-β-苯基-α，β-不饱和羰基，我们先前已证明其在抑制酪氨酸酶中起重要作用。由于肉桂酸相对亲水，这阻碍了它在皮肤上的吸收，因此少了十五种亲水性肉桂酰胺衍生物（1 – 15）被设计为安全且更有效的酪氨酸酶抑制剂，并通过Horner-Wadsworth-Emmons反应合成。使用浓的去苄基化-HCl和乙酸ö苄基-保护的肉桂酰胺40 - 54产生以下三个结果。1）肉桂酰胺类43，48，和53与2,4-组二苄，无论胺类型的酰胺的，产生具有高极性配位化合物。2）肉桂酰胺类40 - 42，44，50 - 52，和54用苄基氨基，或二乙胺基取代产生了所需的脱苄基肉桂酰胺13，5，10

  tyrosinase activity, and the fact that cinnamic acid is a safe natural substance with a scaffolded structure, it was speculated that appropriate cinnamic acid derivatives may exhibit potent tyrosinase inhibitory activity. Thus, ten cinnamamides were designed, and synthesized by using a Horner-Emmons olefination as the key step. Cinnamamides 4 (93.72% inhibition), 9 (78.97% inhibition), and 10 (59.09% inhibition)

  色素沉着障碍归因于酪氨酸酶可能产生过多的黑色素。因此，酪氨酸酶被认为是治疗与色素沉着过度有关的疾病的重要靶标。根据我们先前的发现，（E）-β-苯基-α，β-不饱和羰基支架可以在抑制酪氨酸酶活性方面发挥关键作用，而肉桂酸是具有支架结构的安全天然物质，据推测，适当的肉桂酸衍生物可表现出有效的酪氨酸酶抑制活性。因此，设计了十种肉桂酰胺，并以霍纳-埃蒙斯烯化为关键步骤合成了十种肉桂酰胺。肉桂酰胺4（抑制93.72％），9（抑制78.97％）和10具有2,4-二羟基苯基或4-羟基-3-甲氧基苯基取代基的化合物（抑制率为59.09％）在25 µM处的蘑菇酪氨酸酶抑制作用比曲酸（抑制作用为18.81％）高得多，后者用作阳性对照。特别地，具有2，4-二羟基苯基的两种肉桂酰胺4和9显示出最强的抑制作用。与酪氨酸酶对接模拟显示，这三个cinnamamides，4，9，和10，与曲酸相比，与酪氨酸酶的活性位点的

  construction of chiral 3-substituted tetrahydroquinoline derivatives based on asymmetric dihydroxylation and CoCl2-catalyzed reductive cyclization of nitro cyclic sulfites with NaBH4 has been described with high optical purities. This method has been successfully applied in the formal synthesis of PNU 95666E and anachelin H chromophore.
