An iodine-catalyzed versatile green method for the synthesis of mono- and 2,3-bis-sulfenyl indoles has been presented. Various indoles can react with alkyl or aryl sodium sulfinates using hydrogen peroxide as an oxidizing agent in PEG400 under microwave conditions. This simple method enabled the rapid synthesis of mono- and 2,3-bis-sulfenylindoles with good to excellent yields under metal free conditions
提出了一种用于合成单-和 2,3-双-亚磺基吲哚的碘催化多功能绿色方法。在微波条件下,使用过氧化氢作为氧化剂在 PEG400 中,各种吲哚可以与烷基或芳基亚磺酸钠反应。这种简单的方法能够在无金属条件下快速合成单-和 2,3-双-亚磺基吲哚,收率良好至极好。该协议的显着特点包括环境友好、无味、反应时间短、操作简便、反应条件温和、官能团耐受性好。
