    以对甲氧基苄基奎宁酸酯为关键中间体,通过直接酯化反应高效合成5- O-酰基奎宁酸
    摘要:
    从市售(-)-奎宁酸完成了5- O-酰基奎宁酸的有效和通用合成。我们设计了对甲氧基苄基奎宁酸酯作为关键中间体,并解决了两个问题,即空间位阻的5-OH基团的酯化,以实现简洁的发散合成和最终脱保护步骤的收率低。对于第一个问题,我们通过添加i -Pr 2 NEt改进了田边的方法,即使用游离羧酸的TsCl / NMI介导的酯化反应。对于第二个问题,我们为最终的脱保护步骤建立了TFA或BCl 3 / C 6 HMe 5催化的脱保护反应。5 Ø-酰基奎尼酸通过七个步骤合成,总收率为45-60%。

  • Essential structure of co-pigment for blue sepal-color development of hydrangea
    作者:Tadao Kondo、Yuki Toyama-Kato、Kumi Yoshida
    DOI:10.1016/j.tetlet.2005.07.146
    日期:2005.9
    Blue sepal-color of Hydrangea macrophylla might be due to a supramolecular metal-complex pigment consisting of delphinidin 3-glucoside (1), co-pigments (5-O-caffeoylquinic acid (2), and/or 5-O-p-coumaroylquinic acid (3)) and Al3+ in an aqueous solution around pH 4.0. To clarify the mechanism of blue sepal-color development of hydrangea, we tried to reproduce the blue color in vitro by mixing 1 with designed synthetic co-pigments in the presence of Al3+ at pH 4.0. We at first succeeded in clarifying the essential functional structure in the co-pigment that could form the stable blue solution. Here, we present the structure of the blue pigment caused by an Al-complex coordinating of I at ortho-dihydroxyl groups of the B-ring, 1-hydroxy, 1-carboxylic acid, and the carbonyl residue in the ester at 5-position of 2 and/or 3. The hydrophobic interaction between the aromatic acyl residue at 5-position and the nucleus of 1 may also contribute to stabilize the complex. (c) 2005 Elsevier Ltd. All rights reserved.
  • Efficient and versatile synthesis of 5-O-acylquinic acids with a direct esterification using a p-methoxybenzyl quinate as a key intermediate

    An efficient and versatile synthesis of 5-O-acylquinic acids from commercially available (−)-quinic acid was accomplished. We designed p-methoxybenzyl quinate as a key intermediate, and two problems, the esterification of the sterically hindered 5-OH group for the concise divergent synthesis and the low yield of the final deprotection step, were solved. For the first problem, we improved Tanabe's method
