  Stereoselective Synthesis of 1,3-Dienes from Propargylic Alcohols by LiAlH₄/AlCl₃

  摘要：

  Herein we report that LiAlH4/AlCl3 is a very efficient reagent for the reductive dehydration of aryl propargylic alcohols in tetrahydrofuran solvent at reflux to give 1,3-dienes with good yields and high E selection. The reaction conditions are mild and easy to operate, and a variety of aryl functional groups, such as bromo, fluoro, butyl, and methoxyl groups, are tolerated. With our protocol, useful (E,E)-1,3-dienes can be synthesized. Supplemental materials are available for this article.

  摘要：

  聚甲基氢硅氧烷（PMHS）与CsF的结合有助于炔烃或苯并噻唑与一系列乙烯基，苯乙烯基和芳基卤化物或壬二酸酯以及酰基氯的交叉偶联。实验和光谱证据表明，这些反应涉及甲硅烷氧基中间体的原位生成。这些交叉偶联在室温和无胺条件下进行得相对较快。为了证明该方法的适用性，进行了全细胞毒性丁醇内酯（-）-可可内酯A的合成。

• Lithium Binaphtholate-Catalyzed Enantioselective Enyne Addition to Ketones: Access to Enynylated Tertiary Alcohols
  作者：Hua Cai、Jing Nie、Yan Zheng、Jun-An Ma

  DOI：10.1021/jo5005839

  日期：2014.6.20

  A new catalytic enantioselective enyne addition to ketones has been developed. In the presence of chiral lithium binaphtholate, the addition reaction proceeded smoothly to produce a series of enynylated tertiary alcohols in up to 96% yield and 94% enantiomeric excess. Convenient transformation of the adduct via Pauson–Khand cycloaddition reaction afforded the bicyclic product without detectable loss

  已经开发了一种向酮中添加新的催化对映选择性烯炔的方法。在手性联萘甲酸锂的存在下，加成反应顺利进行，从而产生一系列烯化的叔醇，产率高达96％，对映体过量达94％。通过Pauson-Khand环加成反应对加合物进行方便的转化，得到了双环产物，对映选择性没有可检测到的损失。此外，将三氟甲基酮中的催化不对称烯炔加成用于依夫韦伦类似物的合成中。
• Polymethylhydrosiloxane (PMHS) as an Additive in Sonogashira Reactions
  作者：Robert E. Maleczka Jr.、William P. Gallagher

  日期：——

  Polymethylhydrosiloxane (PMHS) in combination with CsF facilitates the Sonogashira reaction of a variety of alkynes and electrophiles. These couplings appear to involve the in situ formation and reaction of an alkynylsiloxane. Such couplings can be run amine free at room temperature, reaction times are short, workup is easy, and product purification is straightforward. Thus, the advantages (and disadvantages) of running Sonogashira couplings with 1-silylalkynes are realized, without the need to preform the alkynyl silane.

  聚甲基氢硅氧烷（PMHS）与氟化铯（CsF）结合，促进了多种炔烃与电亲核试剂的索诺加希拉反应。这些偶联反应似乎涉及到原位形成和反应炔基硅氧烷。这些偶联反应可以在室温下无胺进行，反应时间短，后处理简单，产品纯化直观。因此，利用1-硅基炔烃进行索诺加希拉偶联反应的优点（和缺点）得以实现，而无需预先制备炔基硅烷。

  Three diacetylene monomer model compounds with similar π-conjugation systems, 10-phenyl-5,7,9-decatriynyl N-phenylcarbamate (1), (E)-10-phenyldec-9-en-5,7-diynyl N-phenylcarbamate (2), and (E)-10-phenyldec-5-en-7,9-diynyl N-phenylcarbamate (3), were synthesized and their properties and solid-state polymerization were investigated. Based on the absorption spectra of the monomers, it was found that the conjugation effect of a double bond was different from that of a triple bond in solution. Monomers 1, 2, and 3 gave one, two, and five crystal forms, respectively, of which 1 and one of the crystal forms of 2 (2a) could be polymerized in the solid state. The conversions after γ-ray irradiation (1 MGy dose) were 53% and 20%, respectively. The longest-wavelength absorption maxima of the polymers prepared from 1 and 2a were 645 and 655 nm, respectively. The polymerizable crystals 1 and 2a were found to have layered monomer structures with spacing of 3.1–3.6 nm. Based on solid-state 13C NMR spectra, the polymerization sites of 1 were determined to be the 1,4- and 3,6-positions with respect to the phenyl ring, and that of 2a was determined to be the 3,6-position with respect to the phenyl ring.

  合成了三种具有相似π-共轭体系的二乙炔单体模型化合物，即10-苯基-5,7,9-十碳三炔基N-苯基氨基甲酸酯（1）、（E）-10-苯基-9-十碳烯-5,7-二炔基N-苯基氨基甲酸酯（2）和（E）-10-苯基-5-十碳烯-7,9-二炔基N-苯基氨基甲酸酯（3），并研究了它们的性质和固态聚合性。根据单体的吸收光谱，发现溶液中双键的共轭效应与三键不同。单体1、2和3分别呈现一种、两种和五种晶型，其中单体1和单体2的一种晶型（2a）可以在固态下聚合。经过γ射线辐照（剂量为1 MGy）后，转化率分别为53%和20%。由单体1和2a制备的聚合物的最长波长吸收最大值分别为645 nm和655 nm。可聚合的晶体1和2a被发现具有层状单体结构，间距为3.1-3.6 nm。根据固态13C NMR光谱，确定了单体1的聚合位点为苯环的1,4-和3,6-位，单体2a的聚合位点为苯环的3,6-位。

  A novel carbonyl alkynylation has been accomplished based on utilization of the Meerwein-Ponndorf-Verley (MPV) reaction system. The success of the MPV alkynylation crucially depends on the discovery of the remarkable ligand acceleration effect of 2,2'-biphenol. For example, the alkynylation of chloral (2c) with the aluminium alkoxide 6(R = Ph), prepared in situ from Me(3)Al, 2,2'-biphenol and 2-me

  基于Meerwein-Ponndorf-Verley（MPV）反应系统的利用，已经完成了新型羰基炔化反应。MPV炔基化的成功关键取决于对2,2'-双酚的显着配体促进作用的发现。例如，由Me（3）Al，2,2'-联苯酚和2-甲基-4-苯基-3-丁炔-原位制备的铝醇盐6（R ​​= Ph）将氯醛（2c）烷基化2-醇（1a）作为炔基来源，在室温下在CH（2）Cl（2）中平稳进行，得到所需的炔丙醇3ca，搅拌5 h后，收率几乎定量。通过不带任何金属炔烃的新转化的特征，可以通过以下事实可视化：带有酮羰基的炔基成功转移到醛羰基上，而酮羰基上没有任何副反应。

  The copper(II)—mediated coupling reaction of alkenyldialkyl- or trialkyl-boranes with alkynylcopper compounds (generated in situ), in the presence of appropriate solvents and a small amount of water, gives (E)-1,3-enynes (or disubstituted alkynes) with various functional groups in reasonable yields.
