  日期：2015.4

  An efficient selectfluor-mediated cyclisation of 2-arylethynyl-benzyl azides at 80 °C in MeCN yielded 12 arylated triazolo-isoindoline derivatives (seven of which are novel). Products bearing either electron-donating or electron-withdrawing groups on the aromatic ring were formed in comparable yields.

  在 80 °C、MeCN 条件下，以选择氟为介质对 2-芳基乙炔基苄基叠氮化物进行高效环化反应，得到了 12 种芳基化的三唑异吲哚啉衍生物（其中 7 种为新型衍生物）。芳香环上带有电子奉献基团或电子吸收基团的产物产量相当。
• Synthesis of Bicyclic Imidazoles via [2 + 3] Cycloaddition between Nitriles and Regioselectively Generated α-Imino Gold Carbene Intermediates

  The cyclic alpha-imino gold carbene intermediate B is most likely generated in situ via regioselective nitrene transfer from an azido group to a tethered terminal alkyne in the presence of a gold catalyst and at ambient temperature. This highly electrophilic intermediate can react with a weakly nucleophilic nitrile, which is used as the reaction solvent, to deliver a bicyclic imidazole rapidly in an overall bimolecular [2 + 2 + 1] cycloaddition and in mostly serviceable yield. The competing intramolecular Huisgen reaction, although likely also catalyzed by gold, is minimized by using AuCl3 as the catalyst.
• Facile Synthesis of [1,2,3]-Triazole-Fused Isoindolines, Tetrahydroisoquino­lines, Benzoazepines and Benzoazocines by Palladium-Copper Catalysed Heterocyclisation­

  An elegant method for the synthesis of 1,2,3-triazoles fused with five-, six-, seven- and eight-membered benzoheterocycles, including isoindoline, tetrahydroisoquinoline, benzoazepine and benzoazocine, has been developed via palladium-copper catalysed reactions in one-pot. The broad scope of this reaction was illustrated by effecting bis-heteroannulations, synthesis of uracil derivatives of biological interest, and employment of acetylene gas as an inexpensive substrate. The reactions are experimentally simple and utilise easily accessible substrates of different types.
