The transition-metal-catalyzed cross-coupling of enamines is an attractive method for producing compounds with an N–C chiral axis; however, it faces considerable challenges that remain unresolved. Herein, a palladium-catalyzed amination method was developed to construct structurally diverse five–six biaryl and six–six nonbiaryl N–C atropisomers. The reaction mechanism was explained using density functional
