  含有恶唑、异恶唑或异噻唑亚基的新型呋喃和噻吩衍生物的实验和理论研究

  摘要：

  摘要在此，我们对新设计的噻吩或呋喃基恶唑、异恶唑和异噻唑衍生物进行了联合实验和理论研究。我们制备目标化合物的合成方法基于范洛森反应。通过遵循该反应，从合适的呋喃或噻吩衍生物与甲苯磺酰甲基异氰化物 (TOSMIC) 的反应中获得含有相关杂环系统的恶唑 (1 和 2)。因此，还首次成功合成了呋喃或噻吩的三个环系，它们与恶唑环的 2 位和 5 位（3 位和 4 位）相连。2-位含有乙酰基的原料与二甲基乙缩醛反应，然后用盐酸羟胺处理，得到所需的异恶唑衍生物（5和6）。此外，异噻唑衍生物（7 和 8）是按照与异恶唑合成相似的方法制备的。所有这些环化反应都以良好到极好的产率发生。通过适当的光谱方法（UV-vis、FT-IR、LC-MS、1H-NMR、13C-NMR和元素分析）进行合成化合物的结构分析。我们还进行了理论研究，以确定结构-活性关系并确定所研究分子的化学性质。为此，我们获得了有关结构特性（键
