pharmaceutical and functional material chemistries. We have accomplished the efficient synthesis of various naphthalene‐linked arenes and heteroarenes as biaryls and heterobiaryls by the FeCl3‐catalyzed Friedel‐Crafts reactions accompanied by the ring‐opening of the 1,4‐epoxy moiety of 1,4‐epoxy‐1,4‐dihydronaphthalenes. Especially, it is noteworthy that 1‐silylated substrates were regioselectively transformed
联芳基和杂联芳基化合物是包括药物和功能材料化学在内的许多领域的重要框架。通过FeCl 3催化的Friedel-Crafts反应以及1,4-环氧-1的1,4-环氧部分的开环,我们已经完成了各种萘联芳烃和杂芳烃作为联芳基和杂联芳基的有效合成,4-二氢萘 尤其值得一提的是,1硅烷化的底物被区域选择性地转化为3芳基1甲硅烷基萘,使用噻吩衍生物的两次Friedel-Crafts反应可以直接产生相应的双萘酚化噻吩衍生物。
