The parallel synthesis of O-aryloxyamines remains an unfulfilled need in the field of medicinal chemistry and fragment-based approaches. To fill this gap a solution-phase two-step process based on (1) a copper-catalyzed cross-coupling of aryl boronic acids with a fluorous tagged N-hydroxyphthalimide, and (2) a supported aminolysis was designed and optimized using Taguchi’s method.

Herein, we report an unprecedented regioselective and entirely atom‐economic cobalt(III)‐catalyzed method for the non‐annulative, intermolecular carboamination of alkenes. The methodology enables the direct synthesis of unnatural aminoacid derivatives and proceeds under redox‐neutral conditions with a completely regioselective C−C bond and C−N bond formation. Furthermore, this reaction exemplifies
在此,我们报道了一种前所未有的区域选择性和完全原子经济的钴(III)催化方法,用于烯烃的非环状,分子间碳氨基化反应。该方法可以直接合成非天然氨基酸衍生物,并在氧化还原中性条件下进行,具有完全的区域选择性C-C键和C-N键形成。此外,该反应例证了Cp * Co III催化剂及其Cp * Rh III对应物固有的不同机理,特别是对于β-H-消除。
