Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

Angewandte Chemie, EarlyView.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

Bis(azuleno)pentalenes with Six Consecutive Odd‐Membered Rings

Angewandte Chemie, EarlyView.
A new class of non‐alternant, non‐benzenoid polycyclic hydrocarbons with a unique 7‐5‐5‐5‐5‐7 odd‐membered ring topology has been synthesized. These compounds possess distinct electronic structures that integrate aromatic azulene and antiaromatic pentalene units, resulting in narrow band gaps, near‐infrared absorption, reversible acid‐base ...

Organocatalyzed Atom Transfer Radical Polymerization (O‐ATRP) Using a Super‐Reducing Photoredox Catalyst

Angewandte Chemie, EarlyView.
A super‐reducing organic photocatalyst expands the scope of O‐ATRP to challenging initiators and monomers. The system enables controlled polymerizations with air tolerance, temporal regulation, and grafting‐from strategies, highlighting the transformative potential of super‐reducing PCs in reversible‐deactivation radical polymerization.
