  General and Facile Synthesis of Indoles with Oxygen-Bearing Substituents at the Benzene Moiety

  摘要：

  Indoles with oxygen-bearing substituents such as a methoxy or (triisopropylsilyl)oxy group at all of the positions of the benzene moiety were synthesized by cyclization of tert-butyl methoxy(or (triisopropylsilyl)oxy)-2-((trimethylsilyl)ethynyl)phenyl)carba- mates with potassium tert-butoxide in tert-butyl alcohol. The (ethynylphenyl)carbamates were synthesized by the palladium-catalyzed reaction of (trimethylsilyl)acetylene and the corresponding (iodophenyl)carbamates, which were selectively synthesized by directed lithiation of the phenylcarbamates and subsequent iodination.

  protecting group is described, using down to near-stoichiometric amounts of hydrogen chloride gas in solvent-free conditions. We demonstrate the ex situ generation of hydrogen chloride gas from sodium chloride and sulfuric acid in a two-chamber reactor, introducing a straightforward method for controlled and stoichiometric release of HCl gas. The solvent-free conditions allow deprotection of a wide variety of

  描述了一种有效、可扩展且可持续的方法，用于在无溶剂条件下使用低至接近化学计量的氯化氢气体对氨基甲酸叔丁酯 ( N -Boc) 保护基团进行定量脱保护。我们展示了在两室反应器中从氯化钠和硫酸异位生成氯化氢气体，介绍了一种用于控制和化学计量释放 HCl 气体的简单方法。无溶剂条件允许对多种N进行脱保护-Boc衍生物以定量产率获得盐酸盐。该程序消除了对任何后处理或纯化步骤的需要，为标准方法提供了一种简单的绿色替代方案。由于无溶剂、无水条件，该方法对酸敏感官能团具有高耐受性，并提供扩展的官能团正交性。

  preferential inhibitor of insulin-like growth factor 1 receptor (IGF-1R) in a panel of 22 protein kinases and in cells. Consistently, 6ha inhibited tumor cell growth in the NCI 60 cell line panel and induced apoptosis. The results indicate that the 5′-position provides limited space for chemical modifications and identify 6ha as a potent water-soluble indirubin-based IGF-1R inhibitor.

  靛玉红已被确定为有效的ATP竞争性蛋白激酶抑制剂。已经对5-和3'-位的结构修饰进行了广泛研究，但是对5'-位的取代基的影响尚未得到充分研究。在这里，我们介绍了通过引入基本中心，在寻找水溶性靛玉红中合成新的靛玉红3'和5'衍生物。评估所有化合物在肿瘤细胞中的抗增殖活性以及所选化合物的激酶抑制作用。结果表明3'-位耐受大取代基而不损害活性，而5'-位的本体和刚性取代基似乎是不利的。筛选水溶性3'-肟醚的分子靶标显示6ha是一组22种蛋白激酶和细胞中胰岛素样生长因子1受体（IGF-1R）的优先抑制剂。一致地，6ha抑制了NCI 60细胞系中肿瘤细胞的生长并诱导了细胞凋亡。结果表明5'-位提供了有限的空间用于化学修饰，并将6ha鉴定为有效的水溶性基于靛玉红的IGF-1R抑制剂。
