The discovery and development of the o-iodoxybenzoic acid (IBX) reaction with certain unsaturated N-aryl amides (anilides) to form heterocycles are described. The application of the method to the synthesis of delta-lactams, cyclic urethanes, hydroxy amines, and amino sugars among other important building blocks and intermediates is detailed. In addition to the generality and scope of this cyclization
描述了邻碘氧基苯甲酸 (IBX) 与某些不饱和 N-芳基酰胺(苯胺)反应形成杂环的发现和发展。详细介绍了该方法在 δ-内酰胺、环氨基甲酸酯、羟基胺和氨基糖等重要结构单元和中间体的合成中的应用。除了这种环化反应的一般性和范围外,本文还描述了许多机理研究,表明单电子从苯胺官能团转移到 IBX,并暗示了该反应的基于自由基的机制。
