Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers

Angewandte Chemie, EarlyView.
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

1,3‐Brook Rearrangement of α‐Silyl Allylic Alcohols: Copper‐Catalyzed Enantiospecific Formation of Allenes and Copper‐Mediated ipso‐Substitution Reactions Affording Trisubstituted Alkenes

Angewandte Chemie, EarlyView.
A regioselective ruthenium catalyzed trans‐hydrosilylation of propargyl alcohols followed by a 1,3‐Brook rearrangement opens access to reactive organocopper intermediates, which evolve upon warming into allenes with strict chirality transfer to the emerging axis; alternatively, these reactive species can be trapped with a large variety of electrophiles

Control of Helix Screw‐Sense Preference in Dynamic Foldamers of meso Symmetry Built From Chiral Monomeric Units

Angewandte Chemie, EarlyView.
Sequence‐diverse meso and “near‐meso” oligourea foldamers are reported and exhibit stimulus‐responsive helix screw‐sense control governed by terminal‐group desymmetrization and sequence‐encoded helix stability. ABSTRACT Meso oligoureas are dynamic hydrogen‐bonded foldamers capable of reversible helix polarity inversion but have so far been limited to ...

Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase

Angewandte Chemie, EarlyView.
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.
