dihalo-substituted analogues of Trogers base. By using paraformaldehyde and TFA, yields of 2-85% of these potential supramolecular building blocks were obtained. Even the inconceivable achievement of condensing anilines unsubstituted in para-position to analogues of Trogers base was successful. Adding our present results to our previous, makes it now possible to synthesize analogues of Trogers base halo-substituted
首次将邻位和间位卤代苯胺与甲醛成功缩合成 Trogers 碱的二卤代类似物。通过使用多聚甲醛和 TFA,这些潜在超分子结构单元的产率为 2-85%。即使是将未取代的苯胺与 Trogers 碱的类似物缩合的不可思议的成就也是成功的。将我们目前的结果添加到我们之前的结果中,现在可以合成 Trogers 碱基的类似物,在其两个芳环中的每一个的几乎任何所需位置上都被卤代取代。此外,Trogers 碱的二卤取代类似物的第一个 X 射线结构,3,9-二溴-4,10-二甲基-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine (17),提出。(© Wiley-VCH Verlag GmbH & Co.
