摘要:
AbstractAn oxidative dearomatizing cyclization of arylamines promoted by iodobenzene bis(trifluoroacetate) [PhI(CF3CO2)2] has been explored, leading to a novel synthetic approach to functionalized spirocyclic building blocks containing the structurally unique dieniminium moiety. This unprecedented methodology, featuring oxidative dearomatization and carbon‐carbon bond‐forming cyclization, to some extent, not only expands the synthetic potential of hypervalent iodine chemistry, but also enriches the oxidation chemistry of arylamines.magnified image
