Imidazoline‐Proline and Imidazoline‐Prolinate Ligands for Copper‐Catalyzed Asymmetric Exo‐Selective [3 + 2] Cycloaddition of Iminoesters with Nitroalkenes

ChemistryEurope, Volume 4, Issue 1, January 2026.
From a modular synthesis of nonphosphine chiral nitrogen‐based chiral imidazoline–amino acid ligands, two new chiral imidazoline–proline‐copper catalysts are developed for targeting exo‐selective [3 + 2] cycloaddition reaction. Density functional theory studies rationalize the observed stereoselectivity and the distinct chiral pockets of the two ...

Aldehyde Electrophilicity and Ring Strain Govern Xylose Acetalization Pathways for Biobased Chemical Production

ChemSusChem, Volume 19, Issue 1, January 2026.
Reaction kinetics and operando heteronuclear single quantum coherence nuclear magnetic resonance studies revealed the reaction pathway of xylose acetalization with different aldehydes. Product distribution and yields were significantly influenced by aldehyde electrophilicity and the orientation of xylose hydroxyl groups.

The Silk Route to Green Catalysis: Silk Fibroin as a Recyclable Ligand for Iron‐Catalyzed Olefin Epoxidation

ChemSusChem, Volume 19, Issue 1, January 2026.
Iron coordinated on silk fibroin from Bombyx mori is easily prepared and catalyzes olefin epoxidation under mild, sustainable conditions with O2. With minimal iron loading, the catalyst is highly recyclable and fully regenerable, offering a green route to heterogeneous catalysis.
