  Synthesis of (7Z,9Z)-dodecadienyi acetate, a component of sex pheromones of the leafrollersEpinotia andEucosma, using conjugated diynols

  摘要：

  Two analogous routes to the title pheromones were elaborated based on organocuprate cross-coupling of Z,Z-dienic electrophiles, (2Z,4Z)-1-acetoxy-2,4-heptadiene (6) and (3Z,5Z)-1-bromoctadiene (8), with omega-tert-butoxy-1-chloropentane and -butane, respectively. Optimal conditions for the reduction of 2,4-heptadiyn-1-ol and 3,5-octadiyn-1-ol to the respective Z,Z-alkadienols as precursors for the electrophiles were found. Treatment of diynols with activated zinc in aqueous alcohol provided high geometrical purity of the product (greater-than-or-equal-to 94 %). In both cases, copper-catalyzed cross-coupling afforded 1-tert-butoxy-7,9-dodecadiene (four stereoisomers), acetolysis of which gave the target pheromone contaminated by stereoisomers. In the case of allylic electrophile 6, the reaction occurred with the loss of the initial configurational purity, whereas the use of homoallylic bromide 8 ensured almost complete retention of the configuration of the double bonds and obtaining the target pheromone of 87 % configurational purity.

  从 1-丁炔到 2E,4Z-heptadien-1-ol 合成路径的比较研究

  摘要：

  摘要 2E,4Z-Heptadien-1-ol (1) 是合成葡萄蛾性信息素的关键中间体，通过多种替代方法从 1-丁炔中获得，包括共轭 E 立体控制构建的各种变体， Z-二烯系统（Cadiot-Chodkiewicz 交叉偶联，炔烃-由钯配合物催化的卤乙烯交叉偶联，阴离子烯丙基重排，三键的部分顺式和反式还原）。它们都不能提供 1 的构型均匀性。以多克的量获得 1 的最可接受的途径似乎是通过共轭二炔醇和烯醇中间体以及随后的催化顺式加氢进行的。

• Synthesis of 1,3-Diynes via Cadiot–Chodkiewicz Coupling of Volatile, in Situ Generated Bromoalkynes
  作者：Phil C. Knutson、Haleigh E. Fredericks、Eric M. Ferreira

  DOI：10.1021/acs.orglett.8b02975

  日期：2018.11.2

  A convenient Cadiot–Chodkiewicz protocol that facilitates the use of low molecular weight alkyne coupling partners is described. The method entails an in situ elimination from a dibromoolefin precursor and immediate subjection to copper-catalyzed conditions, circumventing the hazards of volatile brominated alkynes. The scope of this method is described, and the internal 1,3-diyne products are preliminarily

  描述了一种方便的 Cadiot–Chodkiewicz 方案，该方案有利于使用低分子量炔烃偶联伙伴。该方法需要从二溴烯烃前体中原位消除并立即置于铜催化条件下，从而避免了挥发性溴化炔烃的危害。描述了该方法的范围，并对钌催化的叠氮化物-炔环加成反应中的内部1,3-二炔产物进行了初步评估。
