Direct Synthesis of Substituted Naphthalenes from 1,3-Dicarbonyl Compounds and 1,2-Bis(halomethyl)benzenes Including a Novel Rearrangement Aromatization of Benzo[<i>c</i>]oxepine
unexpected rearrangement aromatization of benzo[c]oxepine has been revealed to synthesize substituted naphthalenes. This observation was further exploited to develop an efficient approach for the construction of naphthalenes from simple and commercially available 1,3-dicarbonylcompounds and 1,2-bis(halomethyl)benzene compounds via a new domino reaction sequence.
苯并[ c ]氧杂环丁烷的意外重整芳构化已表明可以合成取代的萘。进一步利用这一观察结果,开发了一种有效的方法,可通过简单的和可商购的1,3-二羰基化合物和1,2-双(卤甲基)苯化合物通过新的多米诺反应序列来构建萘。
