controllable and synthetically useful base‐promoted intramolecular detosylative cyclization of bis‐N‐tosylhydrazones has been achieved, affording N‐containing heterocycles and cyclic olefins under transition‐metal‐free or gold‐catalyzed procedures, respectively. Moreover, an effective and practical metal‐free or gold‐catalyzed approach to synthesize polycyclic aromatic compounds is also reported.
已实现了对双N-甲苯磺酰hydr的高度选择性,可控和合成有用的碱促进的分子内去甲苯基化环化反应,分别在无过渡金属或金催化的程序下提供了含N的杂环和环烯烃。此外,还报道了一种有效且实用的无金属或金催化的合成多环芳族化合物的方法。
