Diverse frameworks via cycloaddition-rearrangement: Azide-enolate cycloaddition-rearrangements were applied to the direct α-amination of amides and lactams, and synthesis of ene-γ-lactams fromesters. The outcome of the reaction varied by substrate, depending on the fate of triazoline intermediates generated in the cycloaddition. These processes form part of a wider cycloaddition-rearrangement reaction
