7a-hexahydro-3,4,7-metheno-7H-cyclopenta[a]pentalene-7,8-dicarboxylate (3, a 9,10-dihydrofulvalene pincer cycloadduct) was found to be a versatile building block for the synthesis of polynorbornyl scaffolds containing various end functionalities such as porphyrins, pyrimidine, and the phenanthroline ligand in the free and complexed forms. The block is stable under various cycloaddition reaction conditions and
Dimethyl-3,3a,3b,4,6a,7a-hexahydro-3,4,7-metheno-7H-cyclopenta[a]pentalene-7,8-dicarboxylate(3,一种 9,10-二氢富瓦烯钳形环加合物)是被发现是用于合成聚降冰片基支架的通用结构单元,该支架含有各种末端官能团,例如自由和复合形式的卟啉、嘧啶和菲咯啉配体。该嵌段在各种环加成反应条件下稳定,具有较高的π键反应性。使用基于半经验的方法 (AM1) 的分子建模表明,将这种二烯嵌段掺入聚降冰片基系统对其整体结构具有重要影响。特别是,嵌段的加入导致通常在聚降冰片基分子中观察到的曲率变直,从而形成几乎理想的线性多环刚性间隔物。
