  Gold-Catalyzed Tandem Cyclizations of 1,6-Diynes Triggered by Internal N- and O-Nucleophiles

  摘要：

  Investigations on gold-catalyzed tandem cyclization reactions of 1,6-diynes, tethered to nucleophilic functionalities such as amine, carboxylic acid, amide, and sulfonamide, are reported. The ability of such substrates to undergo tandem cyclization, triggered by internal nucleophiles, has been examined. Depending on the substrate, the catalytic system, and reaction conditions, different regioisomers of monocyclic and bridged bicyclic products were obtained.

• Ni(NHC)]-Catalyzed Cycloaddition of Diynes and Tropone: Apparent Enone Cycloaddition Involving an 8π Insertion

  calculations show that the apparent enone cycloaddition occurs through a distinctive 8π insertion of tropone. The initial intramolecular oxidative cyclization of diyne produces the nickelacyclopentadiene intermediate. This intermediate undergoes an 8π insertion of tropone, and subsequent reductive elimination generates the [5–6–7] fused tricyclic product. This initial product undergoes two competing

  Ni/N-杂环卡宾催化剂将二炔偶联到托酮的 C(α)–C(β) 双键上，这种反应在金属催化的环加成与芳香托酮之间是前所未有的。许多不同的二炔有效偶联以提供 [5-6-7] 稠合三环产物，而在少数情况下，[5-7-6] 稠合三环化合物作为次要副产物获得。该反应具有广泛的底物范围和广泛的官能团，并且发现不对称二炔具有优异的区域选择性。理论计算表明，明显的烯酮环加成是通过独特的 8π 插入特酮而发生的。二炔的初始分子内氧化环化产生环戊二烯镍中间体。这个中间体经历了一个 8π 的转酮插入，随后的还原消除产生 [5-6-7] 稠合三环产物。这种初始产物经历了两个相互竞争的异构化，导致观察到的 [5-6-7] 和 [5-7-6] 稠合三环产物。
• An Expeditious Route to Eight‐Membered Heterocycles By Nickel‐Catalyzed Cycloaddition: Low‐Temperature CC Bond Cleavage

  diynes undergo a cycloaddition reaction catalyzed by Ni/IPr to give dihydroazocine compounds (see scheme; IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazolidene). The reaction involves a challenging CC bond cleavage step, yet, surprisingly, proceeds at low temperature.
