N-[2-(haloalkyl)phenyl]imidoyl chloride, which was readily available from the corresponding anilines by using Uneyama's one-pot synthesis of fluorinated imidoyl chloride, was found to be a key intermediate for the facile synthesis of 2-fluoroalkyl substituted indole derivatives via the Grignard cyclization process. The bromination of 3-methyl group of 3-methyl-2-trifluoromethyl indole with NBS/CCl4 led
氟化的N- [2-(卤代烷基)苯基]亚氨基氯,可以通过使用Uneyama的一锅法合成的氟化亚氨基氯从相应的苯胺中容易地获得,被发现是容易合成2-氟烷基取代的关键中间体。通过格氏环化反应制备吲哚衍生物。用NBS / CCl 4将3-甲基-2-三氟甲基吲哚的3-甲基溴化导致形成3-溴甲基取代的吲哚,该吲哚可进一步用于合成一些新的,生物学上感兴趣的吲哚衍生物。
