We report the development of the intramolecular Juliaolefination of imides. This original reaction produces N-fused bicyclic enamide compounds, which are interesting precursors in the synthesis of alkaloids. We show that this transformation enables access to [5,6], [6,5], and [6,6] fused bicyclic lactam enamides. The scope and the limitations of the reaction are presented as well as computational
我们报告了酰亚胺的分子内 Julia 烯化的发展。这种原始反应产生 N-稠合双环烯酰胺化合物,它们是生物碱合成中有趣的前体。我们表明,这种转化能够获得 [5,6]、[6,5] 和 [6,6] 稠合双环内酰胺烯酰胺。介绍了反应的范围和局限性,以及有关标题反应新机理方面的计算研究。
