Probing N-Alkoxy Effects in Domino Reactions of α-Bromoacetamide Derivatives Towards Functionalized γ-Lactams
Résumé
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 equiring 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 Nalkoxy nitrogenated compounds are useful building blocks with powerful but still under-developed synthetic potential, in particular in domino reactions.
