  来自手性磷酸硼配合物和水的手性布朗斯台德酸：吲哚的不对称还原。

  摘要：

  由手性磷酸硼（CPAB）配合物和水原位生成的新手性布朗斯台德酸已成功地用于不对称吲哚还原。如DFT计算所建议的，这种“设计酸催化剂”比TsOH酸性更强，可实现C2-芳基取代的N-未保护的吲哚空前的直接不对称还原，并具有良好的对映选择性，并具有宽泛的官能团耐受性。DFT计算和机理实验表明该反应经历了C3质子化和氢化物转移过程。此外，庞大的C 2-烷基取代的N-未保护的吲哚也适用于该体系。

  New Indole Tubulin Assembly Inhibitors Cause Stable Arrest of Mitotic Progression, Enhanced Stimulation of Natural Killer Cell Cytotoxic Activity, and Repression of Hedgehog-Dependent Cancer

  摘要：

  We designed 39 new 2-phenylindole derivatives as potential anticancer agents bearing the 3,4,5-trimethoxyphenyl moiety with a sulfur, ketone, or methylene bridging group at position 3 of the indole and with halogen or methoxy substituent(s) at positions 4-7. Compounds 33 and 44 strongly inhibited the growth of the P-glycoprotein-overexpressing multi-drug-resistant cell lines NCI/ADR-RES and Messa/Dx5. At 10 nM, 33 and 44 stimulated the cytotoxic activity of NK cells. At 20-50 nM, 33 and 44 arrested >80% of HeLa cells in the G2/M phase of the cell cycle, with stable arrest of mitotic progression. Cell cycle arrest was followed by cell death. Indoles 33, 44, and 81 showed strong inhibition of the SAG-induced Hedgehog signaling activation in NIH3T3 Shh-Light II cells with IC50 values of 19, 72, and 38 nM, respectively. Compounds of this class potently inhibited tubulin polymerization and cancer cell growth, including stimulation of natural killer cell cytotoxic activity and repression of Hedgehog-dependent cancer.

  An efficient synthesis of ketimines was achieved through a regioselective Hg(I)-catalyzed hydroamination of terminal acetylenes in the presence of anilines. The Pd(II)-catalyzed cyclization of these imines into the 2-substituted indoles was satisfactorily carried out by a C-H activation. In a single-step approach, a variety of 2-substituted indoles were also generated via a Hg(I)/Pd(II)-catalyzed,

  在苯胺存在下，通过区域选择性 Hg(I) 催化的末端乙炔加氢胺化，实现了酮亚胺的有效合成。Pd(II) 催化的这些亚胺环化成 2-取代的吲哚通过 CH 活化令人满意地进行。在单步法中，还通过 Hg(I)/Pd(II) 催化的一锅两步法从苯胺和末端乙炔开始生成各种 2-取代吲哚。事实证明，芳基乙炔比烷基衍生物更有效。

  chemistry, and therefore, novel and efficient approaches to their synthesis are in high demand. Among indoles, 2‐aryl indoles have been described as privileged scaffolds. Advanced herein is a straightforward, practical, and transition‐metal‐free assembly of 2‐aryl indoles. Simply combining readily available 2‐fluorotoluenes, nitriles, LiN(SiMe3)2, and CsF enables the generation of a diverse array of indoles

  A new synthesis of 4-halo-1H-indoles has been developed from easily available 2,3-dihalophenol derivatives. The key steps are Smiles rearrangement and a one-pot or stepwise Sonogashira coupling/NaOH-mediated cyclization. Subsequent functionalization allows access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles.

  一种新的合成方法已经从易得的2,3-二卤苯酚衍生物中开发出4-卤代-1H-吲哚。关键步骤是Smiles重排和一步法或分步的Sonogashira偶联/ NaOH介导的环化。随后的功能化允许获得多种2,4-或2,3,4位置选择性功能化的吲哚。

  2,3-Dihaloanilines have been proved as useful starting materials for synthesizing 4-halo-1H-indoles. Subsequent or in situ functionalization of the prepared haloindoles allows the access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles in good overall yields. As no efficient synthetic routes to 2,3-dihaloanilines have been described in the literature, different approaches

  已经证明2，3-二卤代苯胺是用于合成4-卤代-1 H-吲哚的有用的起始原料。所制备的卤代吲哚的随后或原位官能化使得能够以良好的总收率获得各种2,4-或2,3,4-区域选择性官能化的吲哚。由于在文献中没有描述制备2，3-二卤代苯胺的有效合成途径，因此现在提出了制备这些1,2,3-官能化的芳族前体的不同方法。最一般的涉及从相应的2，3-二卤代苯酚的Smiles重排，并允许以直接且合成上有用的方式制备2，3-二卤代苯胺。
