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.
