  设计和合成非肽Ras CAAX模拟物作为有效的法呢基转移酶抑制剂。

  摘要：

  ras癌基因产物Ras的半胱氨酸法呢基化对于其转化活性是必需的，并且被法呢基转移酶（FTase）催化。Ras羧基末端四肽CAAX（C是半胱氨酸，A是任何脂肪族氨基酸，X是蛋氨酸或丝氨酸）是FTase识别的最小序列。我们在这里报告Ras CAAX非肽模拟物的设计，合成和生物学特性，其中半胱氨酸通过还原的伪肽键与4-氨基-3'-羧基联苯相连。这些非肽模拟物是FTase的有效抑制剂（IC50 = 40 nM，是最有效的抑制剂），对FTase的选择性高于GGTase I（香叶基香叶基转移酶I）。它们不是法呢基化的底物，没有肽特征，也没有可水解键。结构活性研究揭示了芳基环上羧酸位置以及半胱氨酸酰胺键还原的重要性。在4-氨基-3'-羧基联苯的2-位取代可提高抑制能力，而羧酸的去除则会导致抑制活性降低10倍。

  甲硅烷基硼烷的异常反应性：芳基、烯基和烷基卤化物与甲硅烷基硼烷/烷氧基碱系统的无过渡金属硼基取代

  摘要：

  已经观察到在烷氧基碱的存在下有机卤化物与甲硅烷基硼烷的意外硼酸化。这种形式上的亲核硼基取代可以应用于具有高官能团兼容性的广泛基材。即使是空间位阻的芳基溴化物也能以高产率提供相应的硼基化合物。初步的机理研究表明，这种硼基取代既不是由过渡金属污染也不是由自由基介导的过程促进的。

  successful synthesis of arylated stibine 3 a in a scale of 34.77 g demonstrates high synthetic potential of this transformation. The formed stibines (R3Sb) were then used for the palladium‐catalyzed carbon–carbon bond forming reaction with aryl boronic acids [R−B(OH)2], giving biaryls with high selectivity, even the structures of two organomoieties (R and R′) are very similar. Plausible catalytic pathways

  镍催化的halostibines交叉偶联，开发了一种形成锑-碳键的策略。该方法已被用于从相应的环状和非环状halostibines合成各种三芳基和二芳基烷基stibines。该方案显示了广泛的底物范围（72个实例），并且与各种官能团（如醛，酮，烯烃，炔烃，卤代芳烃（F，Cl，Br，I）和杂芳烃）兼容。成功合成规模为34.77 g的芳基锑化3a证明了这种转化的高合成潜力。然后将形成的stibines（R 3 Sb）用于与芳基硼酸[ RB （OH）2的钯催化的碳-碳键形成反应，从而产生具有高选择性的联芳基，甚至两个有机基团（R和R'）的结构也非常相似。根据控制实验提出了合理的催化途径。
