We report a method for cobalt-catalyzed, aminoquinoline-directed sp C-H bond carbonylation of sulfonamides. The reactions proceed in a dichloroethane solvent, and employ diisopropyl azodicarboxylate as a carbon monoxide source, Mn(OAc) as a cooxidant and potassium pivalate as a base. Halogen, ester, and amide functionalities are compatible with the reaction conditions. This method allows for a short and efficient synthesis of saccharin derivatives.
我们报道了一种钴催化、氨基喹啉导向的磺酰胺sp C-H键羰基化反应方法。该反应在二氯乙烷溶剂中进行，使用偶氮二羧酸二异丙酯作为一氧化碳源、醋酸锰作为共氧化剂、特戊酸钾作为碱。卤素、酯和酰胺官能团与反应条件兼容。该方法可实现糖精衍生物的短程高效合成。
