Harnessing 'Unproductive' Pathways: Organocatalyst-Mediated Dynamic Kinetic Resolutions via Controlled Racemization

Design trifunctional organocatalysts that combine three activities: (1) perform the desired enantioselective transformation (e.g., aldol addition), (2) catalyze controlled racemization of the starting racemic material to interconvert enantiomers, and (3) spatially separate these functions to prevent racemization of the product. This self-contained dynamic kinetic resolution system would convert 100% of a racemic mixture into a single enantiomeric product, overcoming the 50% yield limitation of traditional asymmetric synthesis from racemates. This approach builds on bifunctional catalyst concepts but applies them in a novel temporal and spatial context, with significant implications for industrial and medicinal chemistry.
