    摘要:
    描述了一系列4-官能化的2,5-二苯基恶唑的制备。已经在电离辐射的存在下评估了每个“闪烁脂质”分子的闪烁效率。在各种制备条件下,已经评估了每个“闪烁脂质”与其他脂质组装成脂质体的能力。已经监测了每种脂质体制剂在电离辐射存在下闪烁的能力。就有效脂质体形成和闪烁效率而言,均已确定最佳的“闪烁脂质”。

    摘要:
    提出了一种电化学碘介导的烯胺酯转化方法,用于合成 2 H-氮丙啶-2-羧酸酯。此外,描述了无需纯化即可定量产率地将氮杂环热转化为 4-羧基-恶唑。 2 H-氮丙啶-2-羧酸酯和 4-羧基-恶唑都是天然产物中的子结构,因此引起了合成化学家和药物化学家的极大兴趣。优化不是以传统方式进行,即一次一个因素的过程,而是采用实验设计( DoE ) 方法。除了广泛的底物范围外,该反应还用于鲁棒性筛选、灵敏度评估,并补充了循环伏安法实验的机制考虑。
