The incorporation of the trifluoromethoxy group into organic molecules has become very popular due to the unique properties of the named substituent that has a “pseudohalogen” character, while the chemical properties of the synthesized compound, especially heterocycles with such a group, are less studied. As trifluoromethoxy-substituted pyrazines are still unknown, we have developed efficient and scalable
由于具有“伪卤素”特征的命名取代基的独特性质,将三
氟甲氧基并入有机分子已变得非常流行,而合成化合物的
化学性质,尤其是具有此类基团的杂环,研究较少。由于三
氟甲氧基取代的
吡嗪仍然未知,我们开发了用于 2-
氯-5-三
氟甲氧基
吡嗪合成的有效且可扩展的方法,显示了该分子在 Buchwald-Hartwig 胺化以及 Kumada-Corriu 和 Suzuki 和 Sonogashira 偶联反应中的合成效用。已经对这些转化中的
氯原子和三
氟甲氧基稳定性进行了一些比较。
