Exclusive Hydroformylation of Terminal Olefins: A Phosphorus‐Free Ruthenium System for the Selective Functionalization of Complex Mixtures

Angewandte Chemie, EarlyView.
Development of a phosphorus‐free Ru/DBU catalyst enabling highly chemo‐ and regioselective hydroformylation of terminal olefins, sparing internal double bonds. Optimization of reaction parameters, ligand effects, and substrate scope including industrial feedstocks was realized.

A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

Angewandte Chemie, EarlyView.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

White‐Light‐Mediated Imidazole Catalysis Toward Terpene‐Based Thermosets

Angewandte Chemie, EarlyView.
White‐light irradiation enables the photoinitiator‐free curing of fully bio‐based terpene epoxy–anhydride systems. A light‐induced switch in epoxide ring‐opening selectivity leads to colorless, transparent thermosets with enhanced thermomechanical performance, revealing an unexpected pathway for sustainable terpene‐based network formation.

Palladium‐Catalyzed Annulations of an Anti‐Bredt Olefin

Angewandte Chemie, EarlyView.
We report metal‐catalyzed trappings of a [2.2.1]‐bridged bicyclic anti‐Bredt olefin (ABO). The methodology yields unusual heterocyclic products and is expected to prompt the further development of unconventional reactions, including metal‐catalyzed processes of ABOs and other strained olefins. ABSTRACT A famous class of alkene‐containing compounds that

Protonation‐Gated Orthogonal Control of Highly Efficient Molecular Motors With Broad Visible‐Light Responsiveness

Angewandte Chemie, EarlyView.
Reversible protonation gates coumarin‐based overcrowded‐alkene molecular motors by dynamically reshaping their conjugation topology. This strategy enables efficient, near‐quantitative unidirectional photoisomerization from blue–green to red‐shifted visible light up to 600 nm, while preserving motor function and allowing orthogonal light, heat, and acid/
