    日期:2015.11.6
    A new synthesis of dibenzo[a,c]anthracene (4) is described that features the generation, from tetrabromo-bis-triflate 1 and phenyllithium, of a 1,3,6-naphthotriyne (2) synthetic equivalent that is trapped with 3 equiv of furan to form Diels–Alder tris-adduct 3. A subsequent two-step deoxygenation of 3 represents the first synthesis of dibenz[a,c]anthracene (4) that involves a tandem aryne Diels–Alder

  • Synthesis of Substituted Trinaphthylenes via Aryne Cyclotrimerization
    作者:Philip T. Lynett、Kenneth E. Maly

    日期:2009.8.20
    The first synthesis of a series of substituted trinaphthylene derivatives via a palladium-catalyzed aryne cyclotrimerization is reported. This method provides an approach for the preparation of novel disk-shaped polycyclic aromatic hydrocarbons that self-assemble via π−π interactions and may form columnar liquid crystal phases. Although the trinaphthylenes prepared in this study do not exhibit columnar
    据报道,通过钯催化的芳烃环三聚反应首次合成了一系列取代的三萘撑衍生物。该方法提供了一种制备新型盘状多环芳烃的方法,该盘状多环芳烃通过π-π相互作用自组装并可能形成柱状液晶相。尽管在此研究中制备的三萘嵌苯不显示柱状中间相,但可变浓度的1 H NMR研究提供了在溶液中聚集的证据。

  • Naphthalene derived chromogenic enzyme substrates
    申请人:Glycosynth Limited
    公开号:US10443084B2
    公开(公告)日:2019-10-15
    Conjugates of 2,3-dihydroxynaphthalene and its derivatives with enzyme cleavable groups are chromogenic substrates that form colored compounds when complexed with metal ions, e.g. iron ions, on cleavage by enzymes, and are useful in microbial detection and identification. The cleavage products form purple or red-brown colored complexes, that can easily be observed by the naked eye. Microbes can be grown in the presence of the substrates and the metal salts that provide the metal ion for complexing with the 2,3-dihydroxynaphthalene product. Substituents in the naphthalene ring may affect the solubility of the substrates and also the diffusibility and color of the metal complexes. Some of the substrates yield soluble complexes on cleavage and are of particular value in liquid growth media. Other substrates produce less soluble complexes that are more suitable for use in solid agar media. Some substrates are new compounds, such as those having the general formula II wherein one of the following applies i) m=0, R4═R5=Z1═H, Y1 is selected from the group consisting of D-glucuronyl and D-ribofuranosyl; ii) m=2, each R6 is Br, R4═R5═H or Br, Z1═H, Y1 is glycosyl or phosphate; iii) m=1, R6 is —SO3X, X is H or M+ wherein M+ is an alkali metal cation or a non-metal cation, Y1 is glycosyl and R4═R5=Z1═H; iv) m=0, R4═NO2, R5═Z1═H, Y1=glycosyl. Methods of synthesizing the substrates are described.
    2,3-二羟基萘及其衍生物与酶可裂解基团的共轭物是一种发色底物,当与金属离子(如铁离子)络合时,在酶的裂解作用下形成有色化合物,可用于微生物检测和鉴定。裂解产物形成紫色或红棕色的复合物,很容易用肉眼观察到。微生物可在底物和金属盐的存在下生长,金属盐可提供与 2,3-二羟基萘产物络合的金属离子。萘环上的取代基可能会影响底物的溶解度以及金属络合物的扩散性和颜色。一些底物在裂解时会产生可溶性络合物,在液体生长介质中具有特殊价值。其他底物产生的络合物溶解度较低,更适合在固体琼脂培养基中使用。 有些底物是新化合物,如通式 II 其中下列情况之一适用 i) m=0,R4═R5=Z1═H,Y1选自由D-葡萄糖醛酸基和D-呋喃核糖基组成的组; ii) m=2,每个 R6 是 Br,R4═R5═H 或 Br,Z1═H,Y1 是糖基或磷酸; iii) m=1,R6 是-SO3X,X 是 H 或 M+,其中 M+ 是碱金属阳离子或非金属阳离子,Y1 是糖基,R4═R5=Z1═H; iv) m=0,R4═NO2,R5═Z1═H,Y1=糖基。 说明了底物的合成方法。
