  Orthogonal Cu- and Pd-Based Catalyst Systems for the O- and N-Arylation of Aminophenols

  摘要：

  O- or N-arylated aminophenol products constitute a common structural motif in various potentially useful therapeutic agents and/or drug candidates. We have developed a complementary set of Cu- and Pd-based catalyst systems for the selective O- and N-arylation of unprotected aminophenols using aryl halides. Selective O-arylation of 3- and 4-aminophenols is achieved with copper-catalyzed methods employing picolinic acid or CyDMEDA, trans-N,N'-dimethyl-1,2-cyclohexanediamine, respectively, as the ligand. The selective formation of N-arylated products of 3- and 4-aminophenols can be obtained with BrettPhos precatalyst, a biarylmonophosphine-based palladium catalyst. 2-Aminophenol can be selectively N-arylated with CuI, although no system for the selective O-arylation could be found. Coupling partners with diverse electronic properties and a variety of functional groups can be selectively transformed under these conditions.

  Copper(II)-catalyzed boronic acid promoted chemoselective N-arylation of unprotected aminophenols has been developed. Selective N-arylation of 3-aminophenol is achieved with a Cu(OAc)2/AgOAc combination in MeOH at rt, whereas the chemoselective N-arylated products of 4-aminophenol can be obtained with a Cu(OAc)2/Cs2CO3 system and benzoic acid as an additive. These ligand-free conditions and “open-flask”

  已经开发了铜（II）催化的硼酸促进未保护的氨基酚的化学选择性N-芳基化。在室温下，使用MeOH中的Cu（OAc）2 / AgOAc组合可实现3-氨基苯酚的选择性N-芳基化，而使用Cu（OAc）2 / Cs 2 CO可获得4-氨基苯酚的化学选择性N-芳基化产物3体系中以苯甲酸为添加剂。这些无配体的条件和“开瓶”化学反应稳定且可与多种官能团兼容。这种选择性氮的机理研究已经通过考虑密度泛函理论（DFT）计算研究了芳基化。
