A straightforward synthesis toward 2-fluorinated aziridines was developed via ring closure of β-fluorinated β-chloroamines, which were obtained via reduction of the corresponding α-fluorinated amides by borane. When 1-benzyl-2-fluoroaziridine was treated with methanol, reaction occurred at the 2-position, giving rise to N-benzyl-2,2-dimethoxyethylamine, while in the case of 1-benzyl-2,2-difluoroaziridine
通过β-氟化β-氯胺的闭环开发了一种直接合成2-氟氮丙啶的方法,该方法是通过用硼烷还原相应的α-氟代酰胺而获得的。当1-苄基-2-氟氮丙啶用甲醇处理时,在2-位发生反应,生成N-苄基-2,2-二甲氧基乙胺,而在1-苄基-2,2-二氟氮丙啶的情况下3 -位被攻击,产生N-苄基-2-甲氧基乙酰胺。这些反应表明单氟-和二氟氮丙啶的反应活性不同。
