    描述了光学活性低聚物 9 和 27 的合成。所需的步骤具有三个基本特征。(1) 溴引导光环化,同时阻断它占据的位置和相邻的位置。(2) 酸清除剂(环氧丙烷)可防止苯甲醚在光环化过程中被消除。(3) 一种碳的立体性控制螺旋缠绕的方向。低聚物是第一个制备的,其中茂金属通过双键的共轭系统连接。它们的光学活性非常高。9 的循环伏安图显示了两个阴极波,它们的接近意味着相邻单元之间的相互作用很弱。当 9 在 Pt 上被电化学还原时,会产生一层中性低聚物。该薄膜具有导电性,可催化电荷转移。它的重量,

To address this issue, herein, five-membered ring-fused selenium-bridged V-shaped binaphthalene with decyl substituents (C10-DNS-VW) is developed and synthesized by an efficient method.

    在高性能有机半导体 (OSC) 的发展过程中,载流子迁移率是下一代基于 OSC 的电子设备的最重要要求。该策略是由高度扩展的 π 电子核心组成的 OSC 表现出二维 (2D) 聚合结构,以提供有效的电荷传输。然而,此类 OSC 通常在常见有机溶剂中的溶解性较差,导致溶液加工性有限。这是开发同时具有高载流子迁移率和合适溶解度的 OSC 之间的关键权衡。为了解决这个问题,本文通过一种有效的方法开发和合成了具有癸基取代基的五元环稠合硒桥联 V 形联萘 (C10-DNS-VW)。C10-DNS-VW 在溶液过程中表现出非常高的溶解度。尤其,C10-DNS-VW 根据晶体生长条件形成一维 π 堆积填充图案(1D 图案)和二维人字形(HB)填充图案(2D 图案)。另一方面,通过溶液工艺和真空沉积技术制造薄膜仅形成 2D HB 图案。外部压力测试,如加热和暴露于溶剂蒸汽表明,一维和二维基序可以通过分子间
  • Determination of the gas-phase acidities of halogen-substituted aromatic compounds using the silane-cleavage method
    作者:Paul G. Wenthold、Robert R. Squires

    日期:1995.1
    The gas-phase acidities of halogen-substituted aromatic compounds have been determined in a flowing afterglowtriple quadrupole apparatus with use of the silane cleavage method developed by DePuy and co-workers [C. H. DePuy, S. Gronert, S. E. Barlow, V. M. Bierbaum and R. Damrauer, J. Am. Chem. Soc., 111, 1968 (1989)]. In this method the relative yields of siloxide ion products produced in reactions of OH− with trimethylsilyl- or phenyldimethylsilyl-substituted aromatic compounds are correlated with the difference in gas-phase acidity of the accompanying neutral products. Acidities are reported for different ring-positions in fluoro-, chloro- and bromobenzene, chloro- and bromonaphthalene and benzyl chloride. Excellent precision is achieved in most cases, with assigned uncertainties less than 2–3 kcal/mol. Good agreement is obtained between the acidities determined with use of two different types of silane precursor. Halogen-substitution increases the gas-phase acidities of benzene and naphthalene by similar amounts (13–14 kcal/mol). The effects on different ring-positions in benzene and naphthalene are shown to be primarily inductive in nature, falling-off by a consistent 2.5–3.5 kcal/mol per bond separating the acidic site from the halogen-bearing carbon in the chlorine and bromine-substituted systems. Larger effects are evident in the positional acidities of fluorobenzene. The meta and para position acidities of halobenzenes are shown to be linearly correlated with the acidities of the corresponding meta and para halophenols, haloanilines and halotoluenes.
    卤素取代的芳香化合物的气相酸性通过使用DePuy及其合作者开发的硅烷裂解法在流动后辉三重四极杆仪器中进行了测定[C. H. DePuy, S. Gronert, S. E. Barlow, V. M. Bierbaum和R. Damrauer, J. Am. Chem. Soc., 111, 1968 (1989)]。在该方法中,与OH−与三甲基硅基或苯基二甲基硅基取代芳香化合物反应所生成的硅氧负离子产物的相对产率与伴随的中性产物的气相酸性差异相关联。不同环位的氟、氯和溴苯、氯和溴萘以及苄氯的酸性结果已被报告。在大多数情况下实现了优异的精确度,赋值不确定性低于2-3 kcal/mol。使用两种不同类型的硅烷前体测定的酸性结果之间获得良好的一致性。卤素取代使苯和萘的气相酸性均增加了相似的值(13-14 kcal/mol)。氯和溴取代体系中,苯和萘中不同环位的影响主要是感应效应,酸性位点与含卤碳原子之间每隔一个键的酸性降低幅度一致为2.5-3.5 kcal/mol。在氟苯的位置酸性中,明显表现出更大的影响。卤苯的对位和间位酸性与相应的间位和对位卤酚、卤代苯胺和卤代甲苯的酸性呈线性相关。
  • Rapid access to substituted 2-naphthyne intermediates via the benzannulation of halogenated silylalkynes

    products undergo desilylation/dehalogenation in the presence of F– to generate the corresponding 2-naphthyne intermediate, as evidenced by furan trapping experiments. When these 2-naphthynes are generated in the presence of a copper catalyst, ortho-naphthalene oligomers, trinaphthalene, or binaphthalene products are formed selectively by varying the catalyst loading and reaction temperature.

    芳烃中间体是用于天然产物和聚合物合成的通用且重要的反应性中间体。2-萘环烷尚未被开发,因为很少有方法为这些中间体提供前体,特别是对于带有其他取代基的中间体。在这里,我们报告通过邻-(苯基乙炔基)苯甲醛与卤代甲硅烷基炔烃的Asao-Yamamoto苯甲环化来获得2-萘炔前体的一般合成策略。该转化提供具有完全区域选择性的2-卤代-3-甲硅烷基萘。这些呋喃捕获实验证明,这些萘产物在F-存在下进行甲硅烷基化/脱卤化生成相应的2-萘中间体。当这些2-萘在铜催化剂存在下生成时,邻萘低聚物,三萘,通过改变催化剂的负载量和反应温度选择性地形成二萘嵌苯或双萘产物。萘产品和萘炔中间体的效率,温和条件和多功能性将为许多新型功能性芳族体系提供有效途径。

  • Hypoxia-Activated Prodrugs: Substituent Effects on the Properties of Nitro <i>seco</i>-1,2,9,9a-Tetrahydrocyclopropa[<i>c</i>]benz[<i>e</i>]indol-4-one (nitroCBI) Prodrugs of DNA Minor Groove Alkylating Agents

    日期:2009.11.26
    Nitrochloromethylbenzindolines (nitroCBIs) are a new class of hypoxia-activated prodrugs for antitumor therapy. The recently reported prototypes undergo hypoxia-selective metabolism to form potent DNA minor groove alkylating agents and are selectively toxic to some but not all hypoxic tumor cell lines. Here we report a series of 31 analogues that bear an extra electron-withdrawing substituent that serves to raise the one-electron reduction potential of the nitroCBI. We identify a subset of compounds, those with a basic side chain and sulfonamide or carboxamide substituent, that have consistently high hypoxic selectivity. The best of these, with a 7-sulfonamide substituent, displays hypoxic cytotoxicity ratios of 275 and 330 in Skov3 and HT29 human tumor cell lines, respectively. This compound (28) is efficiently and selectively metabolized to the corresponding aminoCBI, is selectively cytotoxic tinder hypoxia in all 11 cell lines examined, and demonstrates activity against hypoxic tumor cells in a human tumor xenograft in vivo.
