A new iterative bridge formation strategy has been employed in the synthesis of a series of [n](2,11)teropyrenophanes (n = 7â9). The generation of the nonplanar teropyrene system, which is calculated to be bent through 178.7° for the smallest homologue (n = 7), is accomplished using a VID reaction of a cyclophanemonoene precursor for the first time.
在合成一系列[n](2,11)teropyrenophanes (n = 7â9) 的过程中,我们采用了一种新的迭代桥形成策略。根据计算,最小同系物(n = 7)的非平面芘系统弯曲度为 178.7°,该非平面芘系统的生成首次使用了环番木烯烃前体的 VID 反应。

An improved synthetic pathway to the nanobelt‐like 1,1,9,9‐tetramethyl[9](2,11)teropyrenophane has been developed, and enables the synthesis of gram quantities of material. Key innovations are the development of a sequential chlorination/Friedel–Crafts alkylation reaction, a sequential iodination/Wurtz coupling reaction, and a room‐temperature teropyrene‐forming reaction. The teropyrenophane was found
