Regioselective amination of polyhalogenated heteroarenes (especially pyrimidines) has extensive synthetic and commercial relevance for drug synthesis applications but is plagued by the lack of effective synthetic strategies. Herein, we report the Cu(II)/PTABS-promoted highly regioselective nucleophilic aromatic substitution (SNAr) of polychlorinated pyrimidines assisted by DFT predictions of the bond
多卤杂芳烃(尤其是嘧啶)的区域选择性胺化对于药物合成应用具有广泛的合成和商业相关性,但由于缺乏有效的合成策略而受到困扰。在此,我们报告了 Cu(II)/PTABS 促进的多氯嘧啶的高度区域选择性亲核芳香取代 (S N Ar),并通过 DFT 预测不同 C-Cl 键的键解离能。Cu(II)-PTABS 的独特反应性归因于已知在这些反应中起作用的配位/活化机制,但也提供了对催化物质的进一步见解。
