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 ...

Surface Modification via Click Chemistry Enhances CO2 Reduction Selectivity between C2+/C1 on Shape‐Controlled Cu2O

ChemistryEurope, EarlyView.
Nearly identical molecular modifications of two differently shaped cuprous oxide via click chemistry lead to a striking divergence in product selectivity in CO2 electrolysis—favoring either methane or C2+ compounds. This contrast reveals dual roles of the organic layer : forming distinct functional sites that act synergistically and disrupting copper ...

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...
