The first example of direct reductive amination (DRA) of ketones with electron-deficient amines (EDA) such as Cbz-, Boc-, EtOCO-, Fmoc-, Bz-, ArSO2-, etc. protected amines have been achieved using catalytic Re2O7/NaPF6. Excellent chemoselectivities as well as diastereoselectivity (for 2-alkyl cyclohexanones) were obtained.
首次实现了使用催化剂Re2O7/NaPF6直接还原胺化(DRA)酮与电子贫乏的胺(E
DA)如Cbz-、Boc-、EtOCO-、Fmoc-、Bz-、ArSO2-等保护的胺。获得了优异的
化学选择性和对映选择性(对于2-烷基
环己酮)。
