report the one‐pot synthesis of several N‐heterocyclic compounds by rearrangement reactions of N‐aryl‐2‐vinylaziridines. The optimization of the synthetic methodology employed allowed us to obtain differently substituted 2,5‐dihydro‐1H‐benzo[b]azepines in good yields and purities. The relationship between the nature of the starting N‐aryl‐2‐vinylaziridine and the obtained N‐heterocycle was also investigated
