Ring-opening fluorination reactions of epoxides using tetrabutylammonium bifluoride (TBABF)-KHF2, or Et3N-3HF under microwave irradiation were applied for the introduction of a fluorine atom into the carbohydrate molecules. When TBABF-KHF2 was used as the fluorination reagent, a fluorine atom was introduced regioselectively and various functional groups can tolerate the conditions. When Et3N-3HF was
使用四丁基氟化氢铵(TBABF)-KHF 2或Et 3 N-3HF在微波辐射下进行环氧化物的开环氟化反应,以将氟原子引入碳水化合物分子中。当TBABF-KHF 2用作氟化试剂时,氟原子被区域选择性地引入,并且各种官能团可以耐受该条件。当在微波辐射下使用Et 3 N-3HF时,与传统的油浴加热相比,反应时间可以大大缩短。
