CuH‐Catalyzed Asymmetric Desymmetrization of Cyclobutenes via Stereodivergent Hydroamination

ChemistryEurope, EarlyView.
The CuH‐catalyzed stereodivergent hydroamination through asymmetric desymmetrization of cyclobutenes has been achieved, yielding a range of trisubstituted aminocyclobutanes with excellent results. A series of subsequent transformations, including the first asymmetric synthesis of two pharmaceutically active molecules, have been realized, and density ...
