  One-Pot Synthesis of 2,4-Disubstituted Indoles fromN-Tosyl-2,3-dichloroaniline Using Palladium–Dihydroxyterphenylphosphine Catalyst

  摘要：

  4-Chloroindoles were synthesized from readily available 2,3-dichloroaniline derivatives and terminal alkynes. The catalyst composed of palladium and dicyclohexyl(dihydroxyterphenyl)phosphine (Cy-DHTP) enabled ortho-selective Sonogashira coupling, and subsequent cyclization afforded 4-chloroindoles in high yields. This transformation was successfully applied to the one-pot synthesis of 2,4-disubstituted indoles via Suzuki-Miyaura coupling after indole formation.

• Silver(I)-Mediated CH Amination of 2-Alkenylanilines: Unique Solvent-Dependent Migratory Aptitude
  作者：So Won Youn、Tae Yun Ko、Min Jung Jang、Su San Jang

  DOI：10.1002/adsc.201400759

  日期：2015.1.12

  A highly effective silver(I)‐mediated CH amination of 2‐alkenylanilines has been developed to afford a diverse range of substituted indoles. High functional group tolerance, broad substrate scope, simple/fast/high‐yielding reaction, and recovery/reuse of the inexpensive silver oxidant are noteworthy. Furthermore, an uncommon migratory process of β‐monosubstituted 2‐alkenylanilines with solvent‐dependence

  已开发出一种高效的银（I）介导的2-烯基苯胺的CH胺化反应，以提供各种取代的吲哚。值得注意的是，高官能团耐受性，广泛的底物范围，简单/快速/高产率的反应以及廉价的银氧化剂的回收/再利用。此外，还证明了具有溶剂依赖性的β-单取代2-烯基苯胺的不常见迁移过程。

  Intramolecular hydroamination of alkynyl amides was effected by a catalytic amount of Et2Zn (20 mol %) to form indole derivatives, and a tandem cyclization/nucleophilic addition procedure involving reaction of the indole zinc salt intermediate with acid chlorides or halides was developed to provide an efficient approach to C3-substituted indole derivatives when an excess of Et2Zn (120 mol %) was used

  通过催化量的Et 2 Zn（20 mol％）进行炔酰胺的分子内加氢胺化反应，以形成吲哚衍生物，并开发了涉及吲哚锌盐中间体与酰氯或卤化物反应的串联环化/亲核加成方法，以提供当使用过量的Et 2 Zn（120 mol％）时，一种有效的C3取代的吲哚衍生物的方法。

  The polystyrene supported palladium (Pd@PS) nanoparticles (NPs) catalyzed decarboxylative coupling (DC) of arylhalides and alkynyl carboxylic acids was developed for the synthesis of diaryl alkynes. Indole and 3-pyrroline heterocycles were also synthesized from 2-iodo anilines/amino benzocycloheptene bromide and alkynyl carboxylic acids, following a domino decarboxylative coupling-cyclization (DCC)

  Abstract The cyclization reaction of 2-ethynyl- N -sulfonylanilides proceeded efficiently in water with the presence of a catalytic amount of K 2 CO 3 under transition metal-free condition to give indoles in high yields. The recovery and reusability of the present catalytic system were investigated.

  The reaction of 2-alkenylanilines with SOCl2 in DMSO was found to selectively afford 3-unsubstituted indoles and 3-methylthioindoles. This switchable approach was found to be temperature-dependent: at room temperature, the reaction afforded 3-unsubstituted indoles through intramolecular cyclization and elimination; while at higher temperature, the reaction gave 3-methylthioindoles via further electrophilic

  发现2-烯基苯胺与SOCl 2在DMSO中的反应选择性地提供3-未取代的吲哚和3-甲基硫代吲哚。发现这种可转换的方法是温度依赖性的：在室温下，该反应通过分子内环化和消除得到3-未取代的吲哚；在较高温度下，反应通过进一步的亲电甲基硫醇化反应生成3-甲基硫吲哚。
