  • Gold-Catalyzed Asymmetric Thioallylation of Propiolates via Charge-Induced Thio-Claisen Rearrangement
    作者:Hanbyul Kim、Jiwon Jang、Seunghoon Shin
    DOI:10.1021/jacs.0c09783
    日期:2020.12.9
    A gold(I)-catalyzed enantioselective thioallylation of propiolates with allyl sulfides is described. The key mechanistic element is a sulfonium-induced Claisen rearrangement which helps minimize the allyl dissociation and render higher enantioselectivity. This protocol features remarkable scope of the allyl moiety, allowing enantiocontrolled synthesis of all-carbon quaternary centers, and exhibits
    描述了金 (I) 催化的丙炔酸酯与烯丙基硫化物的对映选择性硫代烯丙基化。关键的机制元素是锍诱导的克莱森重排,这有助于最大限度地减少烯丙基离解并提供更高的对映选择性。该协议具有显着的烯丙基部分范围,允许全碳四元中心的对映控制合成,并与许多路易斯碱和 π 键表现出卓越的官能团兼容性。Claisen 重排的这种分子间变体同时形成 CS 和 CC 键,为获得有趣的光学活性有机硫化合物提供了有效的途径,这些化合物可以通过乙烯基硫化物作为功能手柄进一步转化。对于烯丙基硫化物,反应速率为零级,这表明可逆抑制,为催化剂提供静止状态。哈米特图显示了与 σp 值的相关性,表明限制周转的 σ 重排,其中硫上电子密度的降低加速了重排。

  • Pheromone study on acarid mites. Part IX. Syntheses of alarm pheromone analogues of the mold mite, Tyrophagus putrescentiae, and their biological activities.
    作者:Yasumasa KUWAHARA、Lica SAKUMA
    DOI:10.1271/bbb1961.46.1855
    日期:——
    Against the mold mite, Tyrophagus putrescentiae, 3, 7-dimethyl-(Z)-2-octenyl formate (II) is the most active compound as an alarm pheromone besides the natural pheromone, neryl formate (I), and this activity is equal to I (1-10ppm). In order to elucidate the structural requisites for inducing alarm pheromone activity, a total of 16 analogues of I were prepared by modifying the structure of II. For preparation of 3-methyl- and 3-ethyl-(Z)-2-alkenyl formates, the Wittig reaction of ethoxy- or methoxy-carbonylmethylene triphenyl phosphorane with 2-alkanone or 3-alkanone was used. The reaction with 2-alkanone gave a mixture of (Z)-2-alkenoate (ca. 40%) and (E)-2-alkenoate (ca. 60%) in an average 60% yield. The reaction with 3-alkanone gave a mixture of (Z)-2-alkenoate (56%) and (E)-2-alkenonate (44%). Alarm pheromone activities were demonstrated on 14 compounds of (Z)-2-alkenyl formates. The presence of the (Z)-allylic primary alcohol formate moiety in a molecule was clarified as the key to induce pheromone activity, and no necessity for an acyclic monoterpene carbon skeleton was demonstrated.
    针对霉菌螨(Tyrophagus putrescentiae),3, 7-二甲基-(Z)-2-辛烯酸甲酯(II)是除了天然信息素(奈尔酸甲酯 I)外,作为警报信息素最活跃的化合物,其活性与 I 相当(1-10ppm)。为了阐明诱导警报信息素活性的结构要求,制备了16个 I 的类似物,通过改造 II 的结构。为制备3-甲基和3-乙基-(Z)-2-烯酸甲酯,采用了乙氧基或甲氧基碳酰基甲烯三苯基膦与2-烷酮或3-烷酮的威蒂格反应。与2-烷酮的反应产生了约40%的(Z)-2-烯酸酯和约60%的(E)-2-烯酸酯,平均产率为60%。与3-烷酮的反应则得到了56%的(Z)-2-烯酸酯和44%的(E)-2-烯酸酯。在14种(Z)-2-烯酸甲酯化合物中展示了警报信息素活性。研究表明,分子中存在(Z)-烯丙基初级醇酸甲酯基团是诱导信息素活性的关键,且不需要非环状单萜碳骨架。
