Tandem Chiral Cu(II) Phosphate-Catalyzed Deoxygenation of Nitrones/Enantioselective Povarov Reaction with Enecarbamates
Résumé
A new catalytic enantioselective tandem deoxygenation/aza‐Diels‐Alder reaction of nitrones with enecarbamates was serendipitously discovered in the presence of chiral copper(II) diphosphate complexes. This process affords a wide range of 4‐aminotetrahydroquinolines in respectable yields under mild conditions with good to excellent ee values.
