  • Publication number: 20210238200
    Abstract: The method relates to the field of asymmetric allylic amination and comprises preparing a chiral N-substituted allylic amine compound from the corresponding allylic substrates and substituted hydroxylamines, in the presence of a catalyst, said catalyst comprising copper compounds and a chiral ligand. Examples of chiral amine compounds which can be made using the method include Vigabatrin, Ezetimibe Terbinafine, Naftifine 3-methylmorphine, Sertraline, Cinacalcet, Mefloquine hydrochloride, and Rivastigmine. There are over 20,000 known bioactive molecules with chiral N-substituted allylic amine substructure. The method may also be used to produce non-natural chiral ?-aminoacid esters, a sub-class of chiral N-substituted allylic amine compounds. Examples of ?-aminoacid ester which can be produced by the disclosed method, include, but are not limited to, N-(2-methylpent-1-en-3-yl)benzenamine and Ethyl 2-methylene-3-(phenylamino)butanoate.
