- Abstract: A highly enantioselective Pd‐catalyzed amination of allenyl phosphates generating 2, 3‐allenyl amines with central chirality has been developed. Under the optimized conditions, chiral 2, 3‐allenyl amines with or without (an) additional CC double or triple bond(s) have been prepared at 0 °C with up to 90 % yield and 94 % ee by identifying ( R )‐3, 4, 5‐(MeO)3 ‐MeOBIPHEP as the ligand. Abstract : Chirale 2, 3‐Allenylamine mit oder ohne zusätzliche C‐C‐Doppel‐ oder C‐C‐Dreifachbindung(en) können durch asymmetrische Pd‐katalysierte Aminierung von Allenylphosphaten aufgebaut werden. Unter optimierten Bedingungen, die die Verwendung von ( R )‐3, 4, 5‐(MeO)3 ‐MeOBIPHEP als Ligand und die Durchführung der Reaktionen bei 0 °C beinhalten, wurden die Produkte mit Ausbeuten von bis zu 90 % und 88–94 % ee erhalten.
