Stereoselective Bio‐Organocatalytic Cascade to Chiral Amides as Active Pharmaceutical Ingredient Intermediates Using ω‐Transaminase and Choline Chloride Under Microwave Irradiation

open access: yesChemSusChem, Volume 19, Issue 6, 27 March 2026.
Amide bond formation is central to active pharmaceutical ingredient (API) synthesis. A bio‐organocatalytic cascade is reported, merging stereoselective ω‐transaminase (ω‐TA) transamination in neat organic solvent with choline chloride‐mediated amidation under solvent‐free microwave conditions.

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.
