A straightforward strategy was developed for the arylation and olefination at the C5-position of the N-(alkyl)pyrimidin-2-amine core with readily available aryl halides and alkenes, respectively. This approach was highly regioselective, and the transformation was achieved based on two different (Pd(ii)/Pd(iv)) and (Pd(0)/Pd(ii)) catalytic cycles.
针对N-(烷基)
嘧啶-2-胺核心的C5-位的芳基化和烯化反应,开发了一种简单的策略,分别使用易得的芳基卤化物和烯烃。这种方法是高度区域选择性的,并且基于两个不同的(Pd(ii)/ Pd(iv))和(Pd(0)/ Pd(ii))催化循环实现了转化。
