  • General synthesis of epi-series catechins and their 3-gallates: reverse polarity strategy
    作者:Ken Ohmori、Takahisa Yano、Keisuke Suzuki
    DOI:10.1039/c003464a
    日期:——
    A general synthetic route to the epi-series catechins was developed based on the reverse polarity strategy. Aromatic nucleophilic substitution reaction followed by the sulfinyl–metal exchange and cyclization enabled stereo-controlled access to various members of epi-series catechins and their 3-gallates.
    基于反极性策略,开发了一条合成表儿茶素类化合物的通用合成路线。通过芳香族亲核取代反应、亚磺酰基-金属交换及环化反应,实现了多种表儿茶素及其3-没食子酸酯的立体控制合成。

    DOI:10.1248/cpb.38.856
    日期:——
    A chemical examination of the polyphenolic constituents of the fern, Dicranopteris pedata HOUTT., has led to the isolation of eight new proanthocyanidins possessing a doubly-linked (A-type) unit, together with known flavan-3-ols and proanthocyanidins. On the basis of chemical and spectroscopic evidence, they are characterized as epiafzelechin-(4β→8, 2β→O→7)-eniafzelechin-(4α→8)-epiafzelechin(8), epicatechin-(4β→8, 2β→O→7)-epiafzelechin-(4α→8)-epiafzelechin(9), epiafzelechin-(4β→8, 2β→O→7)-epizfzelechin-(4α→8)-epicatechin(10), epiafzelechin-(4β→8, 2β→O→7)-epicatechin-(4α→8)-epicatechin (11), epicatechin-(4β→8, 2β→O→7)-epiafzelechin-(4α→8)-epicatechin (12), epicatechin-(4β→8, 2β→O→7)-epicatechin-(4α→8)-epiafzelechin (13), epicatechin-(4β→8, 2β→O→7)-epicatechin-(4α→8)-epigallocatechin (14) and epiafzelechin-(4β→8)epicatechin-(4β→8, 2β→O→β→7)-epicatechin-(4α→8)-epicatechin (15).
    通过对蕨类植物 Dicranopteris pedata HOUTT.的多酚类成分进行化学研究,分离出了 8 种新的原花青素,它们与已知的黄烷-3-醇和原花青素都具有双链(A 型)单元。根据化学和光谱证据,它们的特征是表儿茶素-(4β→8, 2β→O→7)-epeniafzelechin-(4α→8)-epiafzelechin(8), 表儿茶素-(4β→8、2β→O→7)-epiafzelechin-(4α→8)-epiafzelechin(9), epiafzelechin-(4β→8, 2β→O→7)-epizfzelechin-(4α→8)-epicatechin(10), epiafzelechin-(4β→8, 2β→O→7)-epicatechin-(4α→8)-epicatechin (11)、表儿茶素-(4β→8, 2β→O→7)-epiafzelechin-(4α→8)-epicatechin (12)、表儿茶素-(4β→8, 2β→O→7)-epicatechin-(4α→8)-epiafzelechin (13)、表儿茶素-(4β→8、2β→O→7)-epicatechin-(4α→8)-epigallocatechin (14) 和 epiafzelechin-(4β→8)epicatechin-(4β→8, 2β→O→β→7)-epicatechin-(4α→8)-epicatechin (15)。
