    摘要:
    描述了花青素-B3(一种儿茶素缩合二聚体)的立体选择性合成。在路易斯酸的存在下,苄基儿茶素与各种4 - O-烷基化的flavan-3,4-二醇衍生物作为亲电试剂的缩合导致被保护的原花青素-B3及其非对映异构体。特别地,在TMSOTf存在下,使用(2 R,3 S,4 S)-3-乙酰氧基-5,7,3',4'-四苄氧基-4-(2“-乙氧基乙氧基)黄酮作为亲电试剂的反应在-78℃下,得到具有高立体选择性和优良分离产率的八-O-苄基化花青素-B3。此外,我们成功地完成了保护性原花青素B3的立体选择性克级合成。

    Deuterium labeled procyanidin syntheses
    摘要:
    Deuterium-labeled procyanidins have been prepared by hemisynthesis from taxifolin in order to investigate their metabolism in human. The structures of the desired deuterated natural compounds B3 10D (R-1=D, R-2=H) and B4 13D (R-1=D, R-2=H) were proven by spectroscopic and physical properties means, including H-2 NMR spectrum. By-products with unatural absolute configuration at some centers were also formed along the process and were characterised. (C) 1997 Elsevier Science Ltd.

  • Stereoselection of 3,4-<i>cis</i> and 3,4-<i>trans</i> Catechin and Catechin Condensation under Intramolecular Coupling Method

    DOI:10.1055/s-2004-830848
    日期:——
    A high level of stereoselection between 3,4-cis and 3,4-trans catechin-catechin condensation under intramolecular coupling method has been realized by changing the diester linker between the nucleophile and the electrophile. The azelaic acid ­linker gave exclusively 3,4-trans catechin-catechin dimer, whereas glutaric acid linker gave 3,4-cis catechin-catechin dimer as the sole product.
    通过改变亲核体和亲电子体之间的二酯连接体,在分子内偶联法下实现了 3,4-顺式和 3,4-反式儿茶素-儿茶素缩合的高度立体选择性。壬二酸连接体只产生 3,4-反式儿茶素-儿茶素二聚体,而戊二酸连接体则只产生 3,4-顺式儿茶素-儿茶素二聚体。

    日期:2003.7
    TMSOTf-catalyzed intramolecular condensation for catechin and epicatechin units are described. A potential electrophile and a nucleophile were connected with diester linkers and TMSOTf-catalyzed condensation was examined. In comparison with intermolecular catechin and catechin condensation, the intramolecular condensation required high reaction temperature and reversed 3,4-cis product was obtained
