the central module, common to all our compounds, is a norbornyl moiety. The acenes are attached to this module using the Diels–Alder reaction, which also forms one of the acene rings. Manipulation of the Diels–Alder adducts provides the desired geometrically defined bis-acenes. The modular nature of this synthesis affords flexibility and allows for the preparation of a variety of acene dimers, including
我们报告降冰片基桥接的并苯二聚体(2和3)的第一个合成与并发生色团亚基之间的定义明确和受控的空间关系。我们采用模块化的2-D策略,其中所有化合物共有的中心模块是降冰片基部分。并苯通过Diels-Alder反应连接到该模块上,该反应也形成并苯并环之一。Diels–Alder加合物的操作提供了所需的几何定义的双并苯。该合成的模块化性质提供了灵活性,并允许制备多种并苯二聚体,包括官能化的并四苯二聚体。
