Abstrakt: The main objective of the present work is to better delineate the positive impact of N‐alkoxy versus N‐alkyl moieties in domino reactions. The key role of the metallic counterion of the basic reagent via a templating effect has been established, giving an insight over the superiority of N‐alkoxy α‐bromoacetamides compared to their N‐alkyl analogues. The former demonstrated enhanced reactivity and efficiency, thus requiring milder conditions and leading to a wider scope of γ‐lactams in good to excellent yields ranging from 67 to 98%. Overall, this study contributes to the emerging point of view that N‐alkoxy nitrogenated compounds are useful building blocks with powerful but still under‐developed synthetic potential, in particular in domino reactions.
