  Synthesis and biological activity of the tea catechin metabolites, M4 and M6 and their methoxy-derivatives

  摘要：

  Syntheses are reported for metabolites M4 (1) and M6 (2) of the green tea polyphenols epicatechin (EC) and epigallocatechin (EGC) and their gallate derivatives. Several methoxy-derivatives of 1 and 2 were also prepared. Compounds 1 and 2 were evaluated for growth inhibitory activity against a panel of immortalized and malignant human cell lines with 1 being the more active compound. The possible antiinflammatory activity of 1 and its trimethoxy derivative was also evaluated. Neither compound inhibited the release of arachidonic acid, although 1 inhibited NO production by 50% at 20 muM. (C) 2005 Elsevier Ltd. All rights reserved.

  as ligands for PdII-promoted organic reactions are reported for the first time. These ligands were utilized as catalytic sites and integrated into the skeleton of conjugated microporous polymers. By employing these CMP materials as selective regulators, oxidative Heck reactions between arylboronic esters and electronically unbiased alkenes provide highly selective linear products.

  首次报道了含有相邻的C≡C基团作为Pd II促进的有机反应的配体的噻吩。这些配体被用作催化位点并整合到共轭微孔聚合物的骨架中。通过将这些CMP材料用作选择性调节剂，芳基硼酸酯与电子无偏烯烃之间的氧化Heck反应可提供高度选择性的线性产物。

  chelate-controlled intermolecular oxidative Heck reaction is reported that proceeds with a wide range of nonresonance stabilized alpha-olefin substrates and organoboron reagents to afford internal olefin products in good yields and outstanding regio- and E: Z stereoselectivities. Pd-H isomerization, common in many Heck reactions, is not observed under these mild, oxidative conditions. This is evidenced

  据报道，一种新型螯合物控制的分子间氧化 Heck 反应与各种非共振稳定的 α-烯烃底物和有机硼试剂一起进行，以良好的收率和出色的区域和 E:Z 立体选择性提供内烯烃产品。在许多 Heck 反应中常见的 Pd-H 异构化在这些温和的氧化条件下未观察到。这可以通过出色的 E:Z 选择性（在所有检查的情况下 >20:1）、近端立体中心的光学纯度没有侵蚀以及对未受保护的醇的耐受性来证明。值得注意的是，单一金属/配体组合，Pd/双-亚砜配合物 1，在广泛的偶联伙伴上催化该反应。鉴于高选择性和广泛的范围，
