  • Keto–enol equilibrium: stable tautomers of <i>ortho</i>-, <i>meta</i>-, and <i>para</i>-hydroquinones in large aromatics
    作者:Vincent Silber、Christophe Gourlaouen、Romain Ruppert

    the 1,4-hydroquinone and 1,4-dihydroxynaphthalene, the stable tautomers for the [4] and [6]helicenes were the aromatic diketones. These experimental results were corroborated by calculations. Additional calculations showed that these tautomeric species were indeed the stable forms of 1,4 and 1,3-hydroquinones when present in larger aromatics, in drastic contrast with 1,2-dihydroxy-aromatics (known as
    提出了以1,4-二甲氧基-[6]螺烯衍生物为原料合成[6]螺烯对醌。三溴化硼的去甲基化反应产生了意想不到的结果。分离出二酮互变异构形式,而不是预期的对氢醌。与1,4-氢醌和1,4-二羟基萘相反,[4]和[6]螺烯的稳定互变异构体是芳香族二酮。这些实验结果通过计算得到了证实。额外的计算表明,这些互变异构体确实是 1,4 和 1,3-氢醌存在于较大芳香族化合物中时的稳定形式,与 1,2-二羟基芳香族化合物(称为儿茶酚)形成鲜明对比。
  • Use of Thiazyl Chlorides, Alkyl Carbamates, and Thionyl Chloride To Fuse 1,2,5-Thiadiazoles to Quinones and To Oxidize, Chlorinate, and Aminate Them
    作者:Shuhao Shi、Thomas J. Katz、Bingwei V. Yang、Longbin Liu
    DOI:10.1021/jo00110a036
    日期:1995.3
    Thiazyl chlorides in a simple one-step procedure fuse 1,2,5-thiadiazole rings to quinones. So do alkyl carbamates mixed with excess thionyl chloride and pyridine. Evidence is put forward to support the hypothesis that NSCl or a related thiazyl derivative is the reactive species that brings about the transformations. Selenoyl chloride mixed with an alkyl carbamate, pyridine, and quinones similarly gives 1,2,5-selenodiazoloquinones. Thionyl chloride in pyridine chlorinates quinones and oxidizes hydroquinones. 2,3-Dichloro-1,4-quinones with S4N4 or. with alkyl N-sulfinylcarbamates give 1,2,5-thiadiazoloquinones. Quinones and their 2 3-dichloro derivatives with TsNSO in pyridine give betaine derivatives of 2,3-diaminoquinones, which pyrrolidine converts into 2-amino-3(tosylamino)quinones. A unified set of mechanisms is presented that accounts for these transformations.

  • Improved Synthesis of 1,4-Phenanthrenequinones from Diels-Alder Cycloadditions of 2-(p-Tolylsulfinyl)-1,4-benzoquinone

    日期:1997.4
    A wide range of substituted 1,4-phenanthrenequinones 5a-g and benz[c]- and benz[a]-1,4-phenanthrenequinones (5h) and (5i) were synthezised in one step through Diels-Alder cycloadditions of 2-(p-tolylsulfinyl)-1,4-benzoquinone 2 and vinylaromatic derivatives 1a-i under thermal and high pressure conditions in moderate to good yields (33-80%).
