Novel improved PMR polyimides [PDF]

A series of N-phenylnadimide (PN) modified PMR polyimide composites reinforced with graphite fibers was investigated. The improved flow matrix resins consist of N-phenylnadimide (PN), monomenthyl ester of 5-norbornene-2, 3-dicarboxylic acid (NE ...

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

ChemSusChem, 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.
