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。
