  摘要：

  描述了蛋白质磷酸酶抑制剂 motuporin 1a 的高度收敛不对称合成。单个肽片段 [34 + 35 --> 51] 的合成和偶联，然后进行大环化，得到完全保护的 motuporin 前体 33，通过脱水和酯水解将其转化为天然产物。使用不对称巴豆基硅烷键构建方法引入与天然产物相关的八个立体中心中的六个。我们的方法的特点是在构型明确的乙烯基锌中间体 22 和 (E)-乙烯基碘化物 7 之间进行有效的 Pd(0) 催化交叉偶联反应，得到化合物 43，从而构建了三取代的 (E, E)-motuporin 侧链的二烯系统。

  element of the cell. There is a diverse group of toxic natural products that inhibit certain phosphatases, thereby disrupting normal biochemical pathways. These toxins can be useful for dissecting the individual biochemical pathways associated with each of these enzymes. This Article describes the first total synthesis of one such toxin, the cyclic heptapeptide microcystin-LA. The synthesis features a convergent

  由激酶和磷酸酶介导的可逆蛋白磷酸化是细胞的主要控制元件。有多种有毒的天然产物会抑制某些磷酸酶，从而破坏正常的生化途径。这些毒素可用于剖析与这些酶中的每一种相关的个体生化途径。本文描述了一种此类毒素的首次全合成，即环状七肽微囊藻毒素-LA。该合成具有收敛路线，可用于寻找选择性磷酸酶抑制剂的类似物制备。描述了一种不寻常的氨基酸 Adda 的新途径，它通过 Suzuki 偶联反应结合了有效的非对映选择性天冬氨酸烷基化和二烯合成。

  Nodularin and microcystins are complex natural cyclic isopeptidic hepatotoxins that serve as subnanomolar inhibitors of the eukaryotic serine–threonine protein phosphatases PP1 and PP2A, enzymes that are intimately involved in controlling cellular metabolism. Previously we described a solution-phase synthesis of stripped-down nodularin analogues; cyclo[-β-Ala-(R)-Glu-α-OMe-γ-Sar-(R)-Asp-α-OMe-β-(S)-Phe-]
