    通过双环化/开环机制的1,4-二甲氧基邻苯二甲酰氮的N-氯化环收缩
    摘要:
    发现并利用亲电子氯化试剂三氯异氰尿酸(TCICA)对1,2-二嗪进行了前所未有的N-氯化环收缩。通过优化和机理分析,确定了n -Bu 4 NCl作为外源性亲核试剂的辅助作用,并将优化的反应条件应用于一系列1,4-二甲氧基邻苯二甲酰肼衍生物。同样,通过使用不稳定的O证明了整体效率的提高。-硅烷基。提出了一种由Favorskii重排启发的双环化/开环机制,并得到DFT计算的支持。此外,在范围扩大方面的努力以及对其他亲电性启动子的评估表明,新开发的环收缩反应性是1,4-二甲氧基邻苯二甲酰胺骨架和TCICA的独特特征。

  • N-Chlorination-induced, oxidative ring contraction of 1,4-dimethoxyphthalazines
    作者:Jeong Kyun Im、ByeongDo Yang、Ilju Jeong、Jun-Ho Choi、Won-jin Chung
    DOI:10.1016/j.tetlet.2020.152048
    日期:2020.6
    A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition
    描述了很少探索的富电子的1,2-二嗪的氧化环收缩。用亲电子氯化试剂(TCICA)处理后,1,4-二甲氧基邻苯二甲azine嗪会经历N-氯化诱导的环收缩,并伴有一个氮原子的损失。用一系列的1,4-二甲氧基邻苯二甲醛衍生物检查了这种异常反应性的范围。另外,基于分离的反应中间体和DFT计算,提出了经由双环物质进行的机理。

    Methods of imaging distribution of myeloperoxidase activity in a subject are disclosed. These methods include the use of bioluminescent substrates, including luminol and wavelength-shifted analogues of luminol. Bioluminescent myeloperoxidase substrates that emit light at longer wavelengths compared to luminol are shown to be useful for imaging myeloperoxidase activity in vivo. The disclosed methods can be used for imaging sites of inflammation and other pathological conditions associated with abnormal levels of MPO activity in vivo. Methods of synthesis of luminol analogues are also disclosed.
