Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach

open access: yesAngewandte Chemie, EarlyView.
An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

A Cholesterol Analogue for Cell‐Surface Enzyme Display

open access: yesAngewandte Chemie, EarlyView.
We report a non‐genetic strategy for bacterial cell surface enzyme immobilisation using cholesterol‐based artificial lipids containing Ni2+‐NTA binding groups that can integrate into biological membranes. The engineered cells can capture His‐tagged enzymes directly from cell lysates while preserving intracellular and surface activity, allowing for ...

A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling

open access: yesAngewandte Chemie, EarlyView.
An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...
