Bis(ketenimines) and bis(carbodiimides) derived from 1,4-bis(2-aminophenyl)-1,3-butadiynes via two independent biradical cyclizations provided, respectively, axially chiral bis(benzocarbazoles) and bis(quinindolines). Mixed biheteroaryls, consisting of benzocarbazole and quinindoline units, have been also prepared by a slightly modified strategy.
通过两个独立的双自由基环化作用分别衍生自1,4-双(2-氨基苯基)-1,3-丁二炔的1,4-双(酮亚胺)和双(碳二亚胺),分别是轴向手性的双(苯并咔唑)和双(喹啉)。由苯并咔唑和喹喔啉单元组成的混合双杂芳基也已通过略微修改的策略制备。
