• An Efficient Method for the Glycosylation of Isoflavones
  作者：Nawaf Al-Maharik、Nigel P. Botting

  DOI：10.1002/ejoc.200800803

  日期：2008.11

  A new efficient, high-yielding glycosylation procedure is described for isoflavones, which employs 2,2,2-trifluoro-N-(p-methoxyphenyl)acetamidates as the glycosyl donors. This methodology was used to prepare the 7-O-glycosides of the three main isoflavones, daidzein, genistein and glycitein. The isoflavones were protected with hexanoyl groups which improved their solubility in organic solvents and

  异黄酮植物雌激素因其正面和负面的健康益处而受到当前的关注。然而，关于它们的吸收、代谢和生物利用度，仍有许多悬而未决的问题。该领域的研究需要获取异黄酮 7-O-葡萄糖苷（在植物中发现的形式）和 7-O-葡萄糖醛酸苷（它们是重要的哺乳动物代谢物）的样本。描述了一种新的高效、高产的异黄酮糖基化程序，它采用 2,2,2-三氟-N-（对甲氧基苯基）乙酰胺作为糖基供体。该方法用于制备三种主要异黄酮、黄豆苷元、染料木黄酮和黄豆黄素的 7-O-糖苷。异黄酮用己酰基保护，这提高了它们在有机溶剂中的溶解度并提高了反应效率。然后采用相同的方法合成类似的 7-O-葡糖苷酸。新的合成将为进一步的生物学研究提供大量这些化合物。(© Wiley-VCH Verlag GmbH & Co.

• A facile synthesis of isoflavone 7-O-glucuronides
  作者：Nawaf Al-Maharik、Nigel P. Botting

  DOI：10.1016/j.tetlet.2006.10.034

  日期：2006.12

  An efficient method is presented for the synthesis of isoflavone 7-glucuronides using a N-(4-methoxyphenyl)-trifluoroacetimidate glucuronsyl donor. A 4-hexanoyl derivative of the isoflavone is used in the coupling reaction, both for protection and to improve solubility. These glucuronides are the human metabolites of estrogenic dietary isotlavones, but their biological activity and pharmacokinetics have yet to be established as until now there were no good methods for their synthesis.

• Highly regioselective dehexanoylation in fully hexanoylated flavonoids

  Highly selective removal of the 7-O-hexanoyl group in fully hexanoylated flavones, isoflavones, flavanone, and flavonol was achieved under mild conditions using K2CO3 in a 1:1 mixture of CH3OH-CH2Cl2. The resulting 7-OH flavonoids are valuable intermediates for the synthesis of flavonoid 7-O-glycosides via phase-transfer-catalyzed (PTC) glycosylation. (C) 2018 Elsevier Ltd. All rights reserved.
