  从酪醇或高香草醇方便地合成羟基酪醇及其亲脂性衍生物。

  摘要：

  羟基酪醇是一种天然存在的具有抗氧化性能的邻酚类化合物，它是通过三步高产率程序从天然和低成本的化合物（例如酪醇或高香草醇）合成的。首先，通过使用碳酸二甲酯（DMC）作为试剂/溶剂，对这些化合物的醇基进行有效的化学选择性保护。其次，用2-碘氧基苯甲酸（IBX）或Dess-Martin高碘烷试剂（DMP）氧化并用连二亚硫酸钠（Na 2 S 2 O 4）原位还原，可以制备羧甲基化羟基酪醇。最终，通过温和的水解步骤，以高收率和高纯度获得了羟基酪醇，这已通过NMR光谱和HPLC谱图得到了证实。通过类似的方法，亲脂性羟基酪醇衍生物被用作药物，食品，和化妆品制剂，都准备好了。实际上，首先，通过使用酰氯在没有任何催化剂的情况下对酪醇和高香草醇的醇基团进行化学选择性保护，以获得相应的亲脂性衍生物，然后将这些化合物以高收率和高纯度转化为羟基酪醇衍生物。 IBX或DMP和Na2S2O4的氧化/还原途径。

  models indicated that hydroxytyrosol fatty acid esters (HTy-Es) could be hydrolyzed by pancreatic lipase to slow-release of free fatty acids (FAs) and HTy. Meanwhile, the HTy-Es, the liberated FAs and the HTy could cross the membrane and were transported into blood circulation. HTy-Es were further hydrolyzed by carboxylesterase in in vitro rat plasma hydrolysis model, which also showed slow-release of

  大鼠外翻肠囊的 HPLC-UV 分析和体外模拟消化模型表明，羟基酪醇脂肪酸酯 (HTy-Es) 可被胰脂肪酶水解，从而缓慢释放游离脂肪酸 (FAs) 和 HTy。同时，HTy-Es、游离的 FAs 和 HTy 可以穿过细胞膜进入血液循环。HTy-Es 在体外被羧酸酯酶进一步水解大鼠血浆水解模型，也显示 FAs (C1-C4) 和 HTy 的缓慢释放。特别是，随着烷基链长度的增加，水解和转运速率先升高后降低。此外，直链HTy-Es的上述速率大于其支链异构体的速率。因此，上述 FAs 和 HTy 在小肠和血液中的持续和缓慢释放清楚地表明 HTy-Es 将是提高游离脂肪酸和羟基酪醇口服生物利用度的有效方法。

  Our group has recently observed a nonlinear tendency in antioxidant capacity of different hydroxytyrosol fatty acid esters in fish oil-in-water emulsions, where a maximum of antioxidant efficiency appeared for hydroxytyrosol octanoate. These results appear to disagree with the antioxidant polar paradox. Because the physical location of the antioxidants in an oil water interface has been postulated as an important factor in explaining this behavior, we have prepared a series of tyrosol and hydroxytyrosol fatty acid esters with different chain length and studied their surface-active properties in water, because these physicochemical parameters could be directly related to the preferential placement at the interface. We have found that tyrosol and hydroxytyrosol fatty acid esters are relevant surfactants when the right hydrophilic-lipophilic balance (HLB) is attained and, in some cases, as efficient as emulsifiers commonly used in industry, such as Brij 30 or Tween 20. Moreover, a nonlinear dependency of surfactant effectiveness is observed with the increase in chain length of the lipophilic antioxidants. This tendency seems to fit quite well with the reported antioxidant activity in emulsions, and the best antioxidant of the series (hydroxytyrosol octanoate) is also a very effective surfactant. This potential explanation of the nonlinear hypothesis will help in the rational design of antioxidants used in oil-in-water emulsions.

  chemoselective protection of the alcoholic group of these compounds was performed by using dimethyl carbonate (DMC) as reagent/solvent; second, the oxidation with 2-iodoxybenzoic acid (IBX) or Dess-Martin periodinane reagent (DMP) and in situ reduction with sodium dithionite (Na2S2O4) allowed the preparation of carboxymethylated hydroxytyrosol; finally, by a mild hydrolytic step, hydroxytyrosol was
