triazine electrophiles are obtained in good yield and react with amine nucleophiles to afford aminotriazine products in good to excellent yield. The nucleophilic aromatic substitution reaction is broad in scope and proceeds smoothly with both aromatic and aliphatic (primary, secondary, and branched) amines in the presence of non-participating functional groups including alcohols, carboxylic acids, indoles
各种二氟甲基-均三嗪是按照简单的合成方案,由简单的市售起始原料制备而成。以良好的产率获得三氯甲基取代的三嗪亲电子试剂,并与胺亲核试剂反应,以良好至优异的产率提供氨基三嗪产物。亲核芳香族取代反应范围广泛,并且在非参与官能团(包括醇、羧酸、吲哚和常见胺保护基团)存在下,芳香族和脂肪族(伯、仲和支链)胺均可顺利进行。此外,大多数反应仅需要催化量的 4-DMAP,无需化学计量的碱,并且在环境温度下两小时内完成。
