Manganese‐Catalyzed Enantioselective Dearomative Epoxidation of Naphthalenes with Aqueous Hydrogen Peroxide

Angewandte Chemie, EarlyView.
The enantioselective epoxidation of naphthalenes into their corresponding arene oxides with aqueous hydrogen peroxide is described. The reaction combines dearomatization with installation of chemically versatile functionality in an enantioselective manner.

Nanochanneling and Local Crystallization Engineering Accelerate Multiphase Single‐Atom Catalysis for Rapid Water Decontamination

Angewandte Chemie, EarlyView.
Crystallinity engineering is applied to carbon microspheres for fabricating transition metal single atoms confined in hydrophilic graphitic nanochannels by precisely etching the amorphous carbon realm. This fine‐tuned nanoenvironment enhances tri‐phase mass transfer and optimizes O3 nonradical activation thermodynamics by inducing the bidental “side‐on”

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

Angewandte Chemie, EarlyView.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction

Angewandte Chemie, EarlyView.
Organoautocatalyzed transamination metathesis of cyclic tertiary amines is disclosed as a high‐yielding, scalable reaction that proceeds under mild, catalyst‐free conditions. It operates via a multi‐step domino reaction mechanism, where an in situ‐formed pyrrolidinium salt functions as a HBD organoautocatalyst.
