regioselectively with the formation of the corresponding 2-adamantyl-5-aryl-2H-tetrazoles. Nitration of these compounds leads to 2-(adamantan-1-yl)-5-(3-nitroaryl)-2Htetrazoles. The structures and composition of the obtained novel 2-adamantyl-5-aryltetrazoles were proven by IR spectroscopy, 1H and 13C NMR spectroscopy, high-resolution mass spectrometry, and also by X-ray structural analysis. According to
5-芳基-NH-四唑与金刚烷-1-醇在浓硫酸中的反应区域选择性地进行,形成相应的2-金刚烷基-5-芳基-2 H-四唑。这些化合物的硝化产生 2-(金刚烷-1-基)-5-(3-硝基芳基)-2 H四唑。所获得的新型2-金刚烷基-5-芳基四唑的结构和组成通过红外光谱、1 H和13 C NMR光谱、高分辨率质谱以及X射线结构分析进行了证明。根据同步热分析数据,所得化合物在高达约 150°C 的温度下是热稳定的。体外研究表明,一些 2-金刚烷基-5-芳基四唑对甲型流感 (H1N1) 病毒具有中等抑制活性。2-[2-(adamantan-1-yl)-2 H -tetrazol-5-yl]-6-bromo-4-nitroaniline 的抗病毒选择性指数 (SI) 显着高于参考 (SI 11)药物金刚乙胺(SI 5)。
