    名称:
    Synthesis and platelet aggregation inhibitory activity of 4,5-bis(substituted)-1,2,3-thiadiazoles
    摘要:
    Routine screening of compounds for inhibition of collagen-induced platelet aggregation in vitro revealed 4,5-bis-(4-methoxyphenyl)-1,2,3-thiadiazole (2) was active and it represents the first example of a 1,2,3-thiadiazole with possible antithrombotic activity. In order to develop a structure-activity relationship for this heterocycle, a number of new 4(5)-mono- and -disubstituted 1,2,3-thiadiazoles were synthesized. These were tested in our screen and a number of additional active compounds were found. The most active compounds (2, 5a, 5b, and 6c) were those in which the heterocycle was substituted with benzene rings possessing para electron-donating groups.

  • Sequential One-Pot Synthesis of Tri- and Tetrasubstituted Thiophenes and Fluorescent Push–Pull Thiophene Acrylates Involving (Het)aryl Dithioesters as Thiocarbonyl Precursors
    作者:Anand Acharya、G. Parameshwarappa、B. Saraiah、H. Ila

    日期:2015.1.2
    An efficient, one-pot three component synthesis of highly functionalized tri- and tetrasubstituted thiophenes has been reported involving (het)aryl dithioesters as thiocarbonyl precursors. Thus, sequential base mediated condensation of readily available (het)aryl active methylene ketones with (het)aryl dithioesters followed by S-alkylation of the resulting enethiolate salts with activated halomethylene
    已经报道了一种高效,一锅三组分的高度官能化的三和四取代噻吩的合成方法,其中涉及(杂)芳基二硫代酯作为硫代羰基前体。因此,容易获得的(杂)芳基活性亚甲基酮与(杂)芳基二硫代酯的顺序碱介导的缩合,然后用活化的卤代亚甲基化合物对所得的烯硫醇盐进行S-烷基化,同时S-烷基化的化合物的分子内醇醛缩合型提供了取代基。噻吩的收率极高。通过使用溴巴豆酸酯作为活化的亚甲基烷基化剂,该方法也已扩展到合成高荧光推挽式取代的噻吩-5-丙烯酸酯。
  • Identification and Quantification of Defect Structures in Poly(2,5-thienylene vinylene) Derivatives Prepared via the Dithiocarbamate Precursor Route by Means of NMR Spectroscopy on <sup>13</sup>C-Labeled Polymers

    routes toward the low band gap polymer poly(2,5-thienylene vinylene) (PTV) and derivatives have been studied. This study describes an extensive NMR characterization of 13C-labeled 3-octyl-PTV and its precursor polymer prepared via the dithiocarbamate route which is, since stable monomers are available, a promising route toward PTV derivatives. By introducing 13C-labeled vinylene carbons, we were able to
    在过去的几十年中,已经研究了几种朝向低带隙聚合物聚(2,5-亚噻吩乙烯)(PTV)及其衍生物的合成途径。这项研究描述了通过二硫代氨基甲酸酯路线制备的13 C标记的3-辛基-PTV及其前体聚合物的广泛NMR表征,由于可获得稳定的单体,因此这是通往PTV衍生物的有希望的路线。通过介绍13C标记的亚乙烯基碳,我们能够定量地表征这些聚合物,同时考虑了会干扰共轭体系的端基和结构聚合缺陷。几种NMR技术和模型化合物的合成被用来完全指定质子和碳的化学位移。此外,将前体向共轭聚合物的经典使用热转化与更平滑,酸诱导的消除过程进行了比较。

    DOI:10.14233/ajchem.2013.15607

    Since alkyl Lewis acids are Brønsted bases, they give a non-acidic reaction media. In this context, acylation of thiophene is investigated in the presence of EtAlCl2 and non-acidic media. Besides 8 examples of thiophene, one example for pyrrole is synthesized in moderate to high yields (up to 99 %).

    日期:2021.7
    A new approach to the synthesis of fused benzothiophene derivatives was developed based on iodine-promoted photocyclization of 4,5-diaryl-substituted thiophenes obtained in three steps from commercially­ available compounds. Comparative analysis showed that photochemical cyclization is a more efficient method for the preparation of fused benzo[b]thiophene derivatives, compared to oxidative coupling
