• Enantioselective Cross-Coupling of <i>meso</i>-Epoxides with Aryl Halides
  作者：Yang Zhao、Daniel J. Weix

  DOI：10.1021/jacs.5b01909

  日期：2015.3.11

  The first enantioselective cross-electrophile coupling of aryl bromides with meso-epoxides to form trans-β-arylcycloalkanols is presented. The reaction is catalyzed by a combination of (bpy)NiCl2 and a chiral titanocene under reducing conditions. Yields range from 57 to 99% with 78–95% enantiomeric excess. The 30 examples include a variety of functional groups (ether, ester, ketone, nitrile, ketal

  首次提出了芳基溴化物与内消旋环氧化物形成反式-β-芳基环烷醇的对映选择性交叉亲电偶联。该反应由(bpy)NiCl 2 和手性二茂钛在还原条件下的组合催化。产率范围为 57% 至 99%，对映体过量为 78-95%。这 30 个例子包括各种官能团（醚、酯、酮、腈、缩酮、三氟甲基、磺酰胺、磺酸酯）、芳基和乙烯基卤化物以及五至七元环。一氧化环辛烯向芳基[3.3.0]双环辛醇的转化强烈暗示了碳自由基的中介作用。

  This study explores a Pd-catalyzed decarboxylative Heck-type Csp3–Csp2 coupling reaction of 2,5-cyclohexadiene-1-carboxylic acid derivatives with vinyl halides to provide γ-olefination products. The olefinated 1,3-cyclohexadienes can be further oxidized to produce meta-alkylated stilbene derivatives. Additionally, the conjugated diene products can also undergo a Diels–Alder reaction to produce a bicyclo[2

  We report the synthesis of N-(α,β-unsaturated acyl)-substituted sulfonimidamides through a Pd-catalyzed carbonylation protocol, employing sulfonimidamides as nucleophiles using CO gas released ex situ, and vinyl/aryl halides and triflates as reagents. The reaction is general and offers a unique class of products in moderate to good yields for a wide range of substrates and electrophiles; for example

• One-Pot Double-Annulation Strategy for the Synthesis of Unusual Fused Bis-Heterocycles
  作者：Shukree Abdul-Rashed、Georgios Alachouzos、William W. Brennessel、Alison J. Frontier

  DOI：10.1021/acs.orglett.0c01351

  日期：2020.6.5

  A novel metal-free double-annulation cascade for the construction of unusual fused heterocyclic systems is described. This simple protocol enables the sequential assembly of two rings in one pot from two simple precursors. Acidic conditions promote the condensation and the intramolecular alkynyl Prins reaction of an enyne or arenyne alcohol with a cyclic hemiaminal to form a five-, six-, or seven-membered

  描述了一种新颖的无金属双环环反应级联，用于构造不寻常的稠合杂环系统。这个简单的协议使得两个简单的前体可以在一个罐中顺序组装两个环。酸性条件促进烯炔或芳烃与环状半缩醛的缩合和分子内炔基普林斯反应，形成五元，六元或七元的氧杂环，然后形成七元或八元的氮杂环。在这种转变中，在一个合成操作中形成三个新的键（一个C–O，一个C–C和一个C–N）会迅速产生化学复杂性。该策略是模块化的，相对通用，可访问一系列独特的稠合双环支架。
• Formation of Enehydrazine Intermediates through Coupling of Phenylhydrazines with Vinyl Halides: Entry into the Fischer Indole Synthesis
  作者：Fuxu Zhan、Guangxin Liang

  DOI：10.1002/anie.201207173

  日期：2013.1.21

  Cut to the chase: Direct formation of an enehydrazine, an intermediate in the classic Fischer indole synthesis, solves the regioselectivity problem associated with indolization. This approach not only achieves selective synthesis of indoles through proper selection of the vinyl halide, but also leads to quick construction of desoxyeseroline and esermethole, as well as the key structural motif in the

  追逐目标：直接形成烯肼（Fischer吲哚经典合成中的中间体）可解决与吲哚化有关的区域选择性问题。这种方法不仅通过卤乙烯的适当选择实现吲哚的选择性合成，而且导致快速施工desoxyeseroline和esermethole的，以及在关键结构基序Akuammiline生物碱vincorine。
