Keywords: amide preparation continuous flow asym hydrogenation enamide dehydroamino acid; heterogeneous chiral rhodium catalyst acid base electrostatic interaction. Let’s learn more about this compound (cas:36620-11-8).
Heterogeneous chiral Rh catalysts based on acid-base and electrostatic interactions have been developed. The robust catalysts demonstrate high activity and selectivity in the continuous-flow asym. hydrogenation of a wide variety of enamides and dehydroamino acids, providing optically active amides without leaching of metal species. The chiral environments can be easily tuned by changing the chiral ligands, demonstrating the high versatility of the heterogeneous catalysts. By applying these efficient catalysts, continuous synthesis of several active pharmaceutical ingredient intermediates was achieved.
