  Enamines and enol ethers are versatile synthons for chemical synthesis. While several methods have been developed to access such molecules, prefunctionalized starting materials are usually required, and direct desaturation methods remain rare. Herein, we report direct desaturation reactions of N-protected cyclic amines and cyclic ethers using a mild I(III) oxidant, PhI(OAc)2, and an electron-deficient

  烯胺和烯醇醚是用于化学合成的通用合成子。尽管已经开发出几种方法来接近这些分子，但是通常需要预官能化的起始材料，并且直接去饱和方法仍然很少。在这里，我们报告了使用温和的I（III）氧化剂PhI（OAc）2和电子不足的五氟苯基卟啉锰Mn（TPFPP）Cl的N-保护的环胺和环醚的直接去饱和反应。该系统显示出各种环状胺和醚的α，β-去饱和的高效率。机理探针表明，去饱和反应是通过最初的α-CH羟基化途径发生的，这可以保护产物免于过氧化。
