  Synthesis and Biological Evaluation of a Natural Ester Sintenin and Its Synthetic Analogues

  摘要：

  Synthesis of 3-(3,4-dimethoxyphenyl)propyl-3-(3,4-dimethoxyphenyl) propanoate (18), a cytotoxic natural ester, was carried out by a convenient synthetic path with a total yield of 49%. Sixteen of its analogues (19-34) were also prepared. Seventeen unsaturated derivatives of 18, compounds 1-17, were also synthesized to examine the structure-activity relationship of this type of ester. All of the synthetic compounds were passed through the cytotoxicity screenings on human tumor cell lines, such as PC-3, Hela, A549, BEL7404, CNE, and KB. Some of the esters exhibited moderate inhibitory effects on these tumor cell lines. The phenolic derivatives exhibited the highest cytotoxicity among these derivatives, while the unsaturated esters were more cytotoxic than the saturated analogues. Some of the compounds also exhibited inhibition on a-glucosidase.

  preliminary studies toward the synthesis of (+)-colveol B. Three strategies, centered on Sharpless asymmetric dihydroxylation, were explored to construct the vicinal syn-dihydroxyl system. The initial attempt involving direct asymmetric dihydroxylation of a chalcone derivative was unsuccessful. Alternatively, successful synthetic routes for (+)-colveol A involved Sharpless dihydroxylation of a cinnamyl

  我们提出了人类 MAO 抑制剂 (+)-colveol A 的第一个对映选择性全合成，并对 (+)-colveol B 的合成进行了初步研究。探索了以 Sharpless 不对称二羟基化为中心的三种策略来构建邻位顺式二羟基化系统。涉及查尔酮衍生物直接不对称二羟基化的最初尝试没有成功。或者，(+)-colveol A 的成功合成路线涉及肉桂酯的 Sharpless 二羟基化、间苯二酚部分的格氏加成、Wittig 反应和 BBr 3介导的 MOM 醚的整体脱保护作为关键步骤。(+)-colveol A 的合成经过 7 个步骤，收率为 30%。
