A selective method for the synthesis of 3-iodo-1,5-benzothiazepin-4-ones via the intramolecular iodocyclization of N-[2-(methylthio)phenyl]propiolamides has been developed. In the presence of I2, iodocyclizations of N-[2-(methylthio)phenyl]propiolamides were conducted smoothly to afford the corresponding 3-iodo-1,5-benzothiazepin-4-ones in moderate to good yields.
开发了一种选择性合成3-碘-1,5-苯噻嗪啶-4-酮的方法,该方法通过N-[2-(甲硫基)苯基]丙炔酰胺的分子内碘环化反应实现。在I2的存在下,N-[2-(甲硫基)苯基]丙炔酰胺的碘环化反应顺利进行,得到了相应的3-碘-1,5-苯噻嗪啶-4-酮,产率中等至良好。
