    Designed Bifunctional Phosphine Ligand-Enabled Gold-Catalyzed Isomerizations of Ynamides and Allenamides: Stereoselective and Regioselective Formation of 1-Amido-1,3-dienes
    摘要:
    By using designed biphenyl-2-ylphosphines functionalized with a remote basic groups as ligands, N-alkynyl-o-nosylamides are directly converted to (1E,3E)-1-amido-1,3-dienes with excellent diastereoselectivities under gold catalysis. With allenamides as substrates, the gold-catalyzed isomerizations are high yielding and applicable to a broad substrate scope including various nitrogen protecting groups and exhibit unprecedented (3E)-selectivities for the distal C-C double bond and good regioselectivities. Combining this gold catalysis with one-pot Diels-Alder reactions leads to rapid assembly of valuable bicyclic compounds.

  • Stille Reactions Catalytic in Tin:  A “Sn−F” Route for Intermolecular and Intramolecular Couplings
    作者:William P. Gallagher、Robert E. Maleczka
    DOI:10.1021/jo0484169
    日期:2005.2.1
    hypercoordinate by KF(aq) allows Me3SnH to be recycled during a Pd(0)-catalyzed hydrostannation/Stille cascade. Starting with a variety of alkynes, in situ vinyltin formation is followed by Stille reaction with aryl, styryl, benzyl, or vinyl electrophiles present in the reaction mixture. Both inter- and intramolecular versions of the process are possible with tin loads of approximately 6 mol %. Regeneration
    由KF (水溶液)超配位的聚甲基氢硅氧烷(PMHS)使Me 3 SnH在Pd(0)催化的氢化锡锡烷/ Stille级联反应过程中得以回收。从各种炔烃开始,在原位形成乙烯基锡,然后与反应混合物中存在的芳基,苯乙烯基,苄基或乙烯基亲电子试剂进行斯蒂勒反应。该方法的分子间和分子内版本都可能具有约6 mol%的锡负载量。认为有机锡氢化物的再生通过Me 3进行SnF中间体。考虑到有机锡氟化物的聚集性质以及以低于化学计量的量使用这些有机锡的能力,与从反应混合物中去除有机锡废料有关的危害和纯化问题被最小化。

  • Synthesis and Solid-State Polymerization of Triyne and Enediyne Derivatives with Similar π-Conjugated Structures
    作者:Kana Mizukoshi、Shuji Okada、Tatsumi Kimura、Satoru Shimada、Hiro Matsuda

    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。
  • Stille Couplings Catalytic in Tin:  The “Sn−O” Approach
    作者:William P. Gallagher、Ina Terstiege、Robert E. Maleczka
    DOI:10.1021/ja0035295
    日期:2001.4.1
    lle coupling protocol for the stereoselective generation of vinyltins and their subsequent union, employing only catalytic amounts of tin, is described. By recycling the organotin halide Stille byproduct back to organotin hydride, a hydrostannylation/cross-coupling sequence can be carried out with catalytic amounts of tin. Such a process is most effective with Me(3)SnCl serving as the tin source. This
    描述了一种一锅串联 Pd 催化的氢化锡烷基化/Stille 偶联方案,用于立体选择性生成乙烯基锡及其随后的结合,仅使用催化量的锡。通过将有机锡卤化物 Stille 副产物再循环回有机锡氢化物,可以用催化量的锡进行氢化锡酰化/交叉偶联序列。这种过程对于作为锡源的 Me(3)SnCl 最为有效。该协议允许将锡需求量减少 94%,同时为各种 Stille 产品保持良好的产量(高达 90%)。此外,由于一个循环需要锡经历至少四次转化,因此在氢化锡烷基化/Stille 序列的过程中,三烷基锡的每个部分都经历了至少 60 次反应。
  • Synthesis, Crystal Structures, and Solid-State Polymerization of 8-[4-(Dimethylamino)phenyl]octa-5,7-diynyl Carbamates

    Six butadiyne monomers with (dimethylamino)phenyl and N-substituted urethane substituents were synthesized and their crystal structures and solid-state polymerization were investigated. In five of the six monomers, directions of the butadiyne stacking and the intermolecular hydrogen bonding between urethane groups coincided, and translational distance d between adjacent butadiyne moieties was around
    合成了六种具有(二甲氨基)苯基和N-取代的氨基甲酸酯取代基的丁二炔单体,研究了它们的晶体结构和固相聚合。在六个单体中的五个中,丁二炔堆叠的方向和氨基甲酸酯基团之间的分子间氢键重合,并且平移距离d相邻的丁二炔部分之间的间距大约为5Å。其中,四种单体的单体的平移轴与丁二炔部分之间的夹角θ约为45°,适用于常规的1,4-加成聚合。这些几何形状导致形成具有特征性的激子吸收和相对高的转化率的聚二乙炔。发现一种单体具有大的θ,并且未发现规则聚合的转化率非常低。然而,在6中的剩余一个单体,丁二炔堆叠和分子间氢键的方向是不同的,并且d比5Å长得多。然而,用于1,4-加成的反应碳之间的距离足够短,导致可比较的转化而无需常规聚合。尽管引入氨基甲酸酯基团对于增加丁二炔的固态聚合的可能性是有效的,但是发现氢键合方向,亚甲基链构象和芳族环的无序提供了在适当条件下的变化。
