A rapid construction of enantioenriched benzo‐fused quinolizidines, indolizidines, and their analogues by ruthenium‐catalyzed asymmetric cascade hydrogenation/reductive amination of quinolinyl‐ and quinoxalinyl‐containing ketones has been developed. This reaction proceeds under mild reaction conditions, affording chiral benzo‐fused aliphatic N‐heterocyclic compounds with structural diversity in good...
Eine Übergangsmetall‐katalysierte asymmetrische Reaktionskaskade aus Hydrierung und reduktiver Aminierung von Chinolinyl‐ und Chinoxalinyl‐Ketonen wird von Q.‐H. Fan et al. in ihrer Zuschrift auf S. 3849 ff. beschrieben. Mit Wasserstoff als Reduktionsmittel arbeiten chirale Ru‐Komplexe ähnlich wie ein chinesisches Wasserrad: Sie überführen Chinolinyl‐ und Chinoxalinyl‐Ketone in enantiomerenangereicherte...
