wide substrate scope is reported. Benzamides with electron‐donating and ‐withdrawing groups and linear, branched, and cyclic alkyl azides are all applicable. Cesium carboxylate is crucial for both reactivity and regioselectivity of the reactions. Many biologically relevant molecules, such as amino acid, peptide, steroid, sugar, and thymidine derivatives can be introduced to arenes with high yields and
据报道,铱催化的芳烃CHH胺化具有广泛的底物范围。具有给电子和吸电子基团以及线性,支化和环状烷基叠氮化物的苯甲酰胺均适用。羧酸铯对于反应的反应性和区域选择性都至关重要。许多生物学上相关的分子,例如氨基酸,肽,类固醇,糖和胸苷衍生物,都可以高收率和100%手性保留率引入芳烃。
