    N-氯化诱导的1,4-二甲氧基酞嗪的氧化环收缩
    摘要:
    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。

    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

    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.
