Methods for the synthesis of hitherto unknown 4-fluoro-4-nitroisoxazolines by fluorination of 4-nitroisoxazoline salts with FClO3 in MeOH and 4-fluoroisoxazoles by treatment of fluoronitroisoxazolines bearing the hydrogen atom bound to the C(5) atom of the isoxazole ring with MeONa in MeOH were developed.
通过在 MeOH 中用 FClO3 氟化 4-硝基异噁唑啉盐,合成迄今未知的 4-氟-4-硝基异噁唑,以及通过在 MeOH 中用 MeONa 处理带有与异噁唑环 C(5) 原子结合的氢原子的氟硝基异噁唑,合成 4-氟异噁唑。
