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 from esters. 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
通过环加成重排的不同框架:叠氮化物-烯醇环加成重排应用于酰胺和内酰胺的直接 α-胺化,以及从酯合成烯-γ-内酰胺。反应的结果因底物而异,这取决于环加成中产生的三唑啉中间体的命运。这些过程构成了更广泛的环加成重排反应流形的一部分,提供了对不同框架的简洁访问。
