碳-碳键的形成与构建是有机合成中的重要研究内容，其中重排反应是形成新的碳-碳键的重要方法之一。因此，新颖的重排反应和模式，不仅具有理论研究的价值，也是开拓新颖反应和键合模式的途径。申请人在前期的工作中，研究了苯并氧杂七元环的重排过程，发现了苯并氧杂七环结构体重排为萘环结构的过程，并进一步发展了一种从简单易得的底物合成萘环衍生物的高效方法。根据文献的调研，氧杂七环的反应性研究是一个尚未涉猎的研究点，具有巨大的理论意义和潜在价值，迫切需要进行深入研究。因此本项目将详细的研究这一反应的转化过程，并利用这一反应实现芳香家族的其它基本结构体（如苯环，苯并杂环，蒽环）的合成，同时将对各种杂七环的重排及开环反应作进一步的研究，以期发现新的重排反应过程和碳-碳键形成的新方法。

The formation of carbon-carbon bond is a basic research topic in organic synthesis, while rearrangement reaction is one of the most important way in the formation of new carbon-carbon bonds. Thus, the novel rearrangement reactions and patterns, not only have the value of theoretical research , but also open up new reaction pathways and bonding process. In recent work of our reseach on benzo[c]oxepine, a novel rearrangement process was found and which was further exploited to develop an efficient approach for the construction of naphthalenes from simple and commercially available reagents. According to the research literature, the rearrangement process of this benzo[c]oxepine is an uncovered reseach field with great theoretical significance and potential value and urgent need for further research. Therefore, this project will be a detailed study of this rearrangement process, and using the conversion for the synthesis of other basic structures of aromatic family (eg.benzene, benzo-heterocyclic, polycyclic aromatic). Addition work will focus on the rearrangement and ring-opening reaction of other heteroatom contained seven-numbered rings in order to discover novel rearrangement processes and new paths of carbon-carbon bond formation.
