  2-(2-alkylethynyl)benzonitrile with sodium methoxide in refluxing methanol for 12 h gave 3-alkyl-1(2H)-isoquinolone in modest yield. Under the same reaction conditions, methanolysis of 2-(2-arylethynyl)benzonitrile lead to the formation of 3-alkylidene isoindol-1-one. Partial hydrolysis of 2-(1-hexynyl)benzonitrile to the corresponding benzamide, followed by treatment of the benzamide with sodium methoxide

  在回流的甲醇中用甲醇钠处理2-（2-烷基乙炔基）苄腈12小时，得到3-烷基-1（2H）-异喹诺酮，收率适中。在相同的反应条件下，2-（2-芳基乙炔基）苄腈的甲醇分解导致3-亚烷基异吲哚-1-酮的形成。2-（1-己炔基）苄腈部分水解成相应的苯甲酰胺，然后在回流的甲醇中用甲醇钠处理苯甲酰胺，以49％的收率得到3-亚戊叉基异吲哚-1-酮。这表明苯甲酰胺不参与该环化反应。

  Exploration of elementary reactions in organometallic catalysis is an important method with which to discover new reactions. In this article, we report a gold(I)‐catalyzed iodo‐alkynylation of benzyne involving the merging of challenging migratory insertion and an oxidative addition process in gold catalytic cycle. A wide range of structurally diverse alkynyl iodides are good coupling partners in this iodo‐alkynylation transformation. Both aliphatic and aromatic alkynyl iodides can react with benzynes smoothly to afford highly functionalized 1,2‐disubstituted aromatics in moderate to good yields. Its good functional group compatibility and late‐stage application of complex molecules demonstrate its synthetic robustness. Studies of the mechanism reveals the feasibility of oxidative addition and the DFT calculations demonstrate the possible migratory insertion of benzyne into Au^III‐carbon bonds in the Au^I/Au^III redox catalytic cycle, representing an important step towards an elementary reaction in gold chemistry research.

  摘要 探索有机金属催化中的基本反应是发现新反应的重要方法。本文报告了一种金（I）催化的苄基碘炔化反应，涉及金催化循环中具有挑战性的迁移插入和氧化加成过程的合并。在这种碘-炔基转化过程中，多种结构不同的炔基碘化物都是很好的偶联剂。脂肪族和芳香族炔基碘化物都能与苄基化合物顺利发生反应，以中等至良好的收率得到高度官能化的 1,2-二取代芳烃。其良好的官能团兼容性和复杂分子的后期应用证明了它的合成稳定性。对其机理的研究揭示了氧化加成的可行性，而 DFT 计算则证明了在 AuI/AuIII 氧化还原催化循环中，苄基可能会迁移插入 AuIII 碳键，这代表着向金化学研究的基本反应迈出了重要的一步。

  Treatment of 2-((Z)-6-substituted-3-hexene-1,5-diynyl)benzonitriles with sodium methoxide in refluxing methanol in the presence of a polar aprotic solvent, such as DMSO, HMPA, THF, or 18-crown-6, gave phenanthridinones in 21-77% yields. In these cases, addition of 10% DMSO into the reaction mixture gave the highest yield. On the other hand, methanolysis of 2-(2-(2-dalkynylphenyl)ethynyl)benzonitriles under the same reaction conditions gave benzo[c]phenanthridinones in 31-57% yields. Methanolysis of (Z)-1-aryl-3-hexen-1,5-diynes in the presence of 2 equiv of tetrabutylammonium iodide gave biaryls in 14-64% yields. It is found that the reactions with aryl groups bearing electron-withdrawing groups proceeded at greater rates and gave better yields.

  The activities of a series of acyclic enediynes, 2-(6-substituted hex-3-ene-1,5-diynyl)benzonitriles (1-5) and their derivatives 7-23 were evaluated against several solid tumor cell lines and topoisomerase I. Compounds 1-5 show selective cytotoxicity with Hepa cells, and 2-[6-phenylhex-3-ene-1,5-diynyl]benzonitrile (5) reveals the most-potent activity. Analogues 8-10 and 13-22 also have the same effect with DLD cells; 1-[(Z)-dec-3-ene-1,5-diynyl]-4-nitrobenzene 21 shows the highest activity among them. Moreover, 1-[(Z)-dec-3-ene-1,5-diynyl]2-(trifluoromethyl)benzene (20) exhibits the strongest inhibitory activity with the Hela cell line. Derivatives 9, 10, 18, and 23 display inhibitory activities with topoisomerase I at 87 mum. The cell-cycle analysis of compound 5, which induces a significant blockage in S phase, indicates that these novel enediynes probably undergo other biological pathways leading to the cytotoxicity, except the inhibitory activity toward topoisomerase I.
