Considering the biological and chemical relevance of guanidine containing derivatives, we have devised a novel and efficient two-step synthesis of 2-arylamino-1,4,5,6-tetrahydropyrimidines. We have found that the coupling of aryl bromides with 2-aminopyrimidine is a very effective method for the high yielding synthesis of 2-arylaminopyrimidines. Moreover, the employment of Pd-catalysed hydrogenation
考虑到含有胍的衍生物的生物和化学相关性,我们设计了一种新型有效的 2-芳基氨基-1,4,5,6-四氢嘧啶的两步合成方法。我们发现芳基溴化物与 2-氨基嘧啶的偶联是一种非常有效的 2-芳基氨基嘧啶合成方法。此外,使用 Pd 催化的氢化来选择性地还原嘧啶环产生了一条非常高产的途径,以获得具有生物学意义的 2-芳基氨基-1,4,5,6-四氢嘧啶。
