Different chemoselectivities of phenols and thiophenols were observed in a Tf2O-promoted C3 functionalization of simple anthranils. The reaction of phenols and anthranils gives 3-aryl anthranils via a C–C bond formation, whereas thiophenols afford 3-thio anthranils through a C–S bond formation. Both reactions have a broad substrate scope and tolerate a wide range of functional groups, affording the
在 Tf 2 O 促进的简单邻氨基苯甲酸 C3 官能化中观察到苯酚和苯硫酚的不同化学选择性。苯酚和邻氨基苯甲醚的反应通过 C-C 键形成生成 3-芳基邻氨基苯甲醚,而苯硫酚通过 C-S 键形成反应生成 3-硫代邻氨基苯甲醚。两种反应都具有广泛的底物范围并耐受多种官能团,从而提供具有特定化学选择性的相应产物。
