  咔唑系列硝化

  摘要：

  在乙酸酐溶液中硝化9-甲苯磺基咔唑得到1-硝基（28％），2-硝基（19％）和3-硝基（53％）衍生物。由9-乙酰基咔唑得到的硝基化合物的混合物分别包含10％，48％和42％的异构体。在类似条件下，9-亚硝基咔唑显示出不同的异构体分布：34％的1-硝基和66％的3-硝基咔唑。咔唑的硝化是两步过程，涉及9-硝基咔唑的形成和重排。1,3,6,8-四氯咔唑的硝化作用和9-硝基咔唑的氧化作用以及硝化条件下9-硝基咔唑的重排结果支持了这一假设。

  carbazoles, benzothiophenes and benzofurans are important motifs in the pharmaceutical industry. Herein we report a novel, regioselective method to introduce alkyl substituents into position ortho of nitro groups by the addition of a Grignard reagent followed by subsequent oxidation with DDQ.

  取代的吲哚，咔唑，苯并噻吩和苯并呋喃是制药行业的重要主题。在本文中，我们报道了一种新颖的区域选择性方法，该方法通过添加格氏试剂将烷基取代基引入硝基邻位，随后用DDQ进行氧化。

  Transition metal-catalyzed diamination by hydroxylamines is a common approach for making three-membered aziridines, while its use for building the larger N-heterocycles is still underdeveloped. Herein, we report an efficient Pd(0)-catalyzed inter-molecular [4+1] annulation of o-bromo(or chloro)-biaryls with bifunctional secondary hydroxylamines for the one-step assembly of synthetically useful carbazoles

  羟胺的过渡金属催化二化是制备三元氮丙啶的常用方法，而其用于构建较大的N-杂环的用途仍未开发。在此，我们报告了一种有效的 Pd(0) 催化的分子间 [4+1] 环化邻溴（或氯）-联芳基与双功能仲羟胺，用于一步组装合成有用的咔唑。值得注意的是，这种多米诺骨牌反应的关键是明智地选择氨基源和 Pd(0)-催化剂，以便在具有不稳定 NO 的羟胺存在下将芳基卤化物氧化加成到 Pd(0)-物种中。键。

  Deploying N-nitrosaccharin reagents in combination with Lewis acid activation enables the facile, regio- and chemoselective nitration of (het)aryl silanes, allowing the introduction of nitro group under unprecedently mild conditions suitable for the late-stage nitration of complex and polyfunctionalized molecules. Theoretical and experimental mechanistic investigations formulate a plausible mechanism

• Carbazole N-substituent effect upon DTMA: stabilizing and photochromic modulating
  作者：Zhiming Huo、Zhipeng Li、Tingting Wang、Heping Zeng

  日期：2013.10

  Dithienylmaleimide derivatives 7-27 were synthesized by introducing N-substituted carbazole for photo-stabilizing purpose, and the structures were fully confirmed. The photochromism and photo-stability were recorded via UV-vis spectra. Only ortho compounds 8-17 with N-substituents on carbazole moiety showed escalated photochromic change, while compound 7 and the para counterparts 18-27 showed no appreciable photochromism. Additionally, compounds 8-18 exhibited good photo-stability except 17 under 254 nm irradiation. The unstability of 17 may probably due to overrunning hindrance. These photochromic patterns indicated that hindrance and electronic effect mutually paid a decisive influence on the photochromism and photo-stability, which potentially exploited a new way to construct novel photochromic materials with regulable and conceivable performance.

  日期：2011.7.15

  A Pd-catalyzed oxidative C-H amination of N-Ts-2-arylanilines under ambient temperature using Ozone as an inexpensive, safe, and easy-to-handle oxidant has been developed. This process represents a green and practical method for the facile construction of carbazoles with a broad substrate scope and wide functional group tolerance.
