An efficient approach for the synthesis of unsymmetrically substituted Troger's base derivatives is reported. This approach is based on the N-alkylation of an arylamine by tert-butyl [2-(bromomethyl)aryl]carbamate to give the corresponding diamine, which is subsequently converted into a Troger's base derivative using paraformaldehyde in trifluoroacetic acid. The mild conditions of this approach allow
报道了一种合成不对称取代的 Troger 碱衍生物的有效方法。该方法基于芳胺被[2-(溴甲基)芳基]氨基甲酸叔丁酯N-烷基化,得到相应的二胺,随后在三氟乙酸中使用多聚甲醛将其转化为Troger碱衍生物。这种方法的温和条件允许制备带有对还原条件敏感的吸电子官能团的 Troger 碱衍生物,正如以 62% 至 76% 的总产率制备 12 种 Troger 碱衍生物所证明的那样。
