AbstractN-Heterocyclic carbenes were round to be efficient catalysts for the formal [2 + 2] cycloaddition of aryl(alkyl)ketenes and diazenedicarboxylates to give the corresponding aza-beta-lactams in good yields with up to 91% ee. The N-substituent (carboxylate vs benzoyl) of diazenes played an Important role to control the reaction modes (formal [2 + 2] vs [4 + 21 cycloaddtions).
