Ketone reductive amination
WebRecently, we have found a sub-class of IREDs that display a remarkable reductive amination activity in some cases at near-stoichiometric ketone to amine ratios, prompting us to name them reductive aminases (RedAms) due to the importance of this transformation in synthetic organic chemistry. Web10 mrt. 2024 · This dissertation focuses on the development of amine-boranes and their novel monotrifluoroacetoxy-derivatives as efficient and environmentally friendly reagents for reductive amination. Trimethyl borate, as a lewis acid, is shown to improve the chemoselectivity of amine-boranes while promoting faster imine formation. Refinement of …
