room temperature gave α-chloro cis-aziridines. Additionally, with Bu3SnH as the reductant, α-(dichloromethyl)amines were readily obtained from easily accessible α-(trichloromethyl)amines via mono-dechlorination. Over-reduction was successfully suppressed. Subsequent radical mono-dechlorination of the α-(dichloromethyl)amines gave the corresponding α-(chloromethyl)amines in good to excellent yields
提出了立体选择性合成α-(二
氯甲基)胺,α-(
氯甲基)胺和α-
氯氮丙啶的方案。基于芳族N-叔
丁基亚砜基
亚胺与(二
氯甲基)三甲基
硅烷在低反应温度下的亲核二
氯甲基化,实现了α-(二
氯甲基)胺的非对映选择性合成。将反应混合物缓慢升温至室温,得到α-
氯顺式-
氮丙啶。另外,使用Bu 3 SnH作为还原剂,可通过以下途径从容易获得的α-(三
氯甲基)胺中轻松获得α-(二
氯甲基)胺:单脱
氯。过度减少被成功抑制。随后对α-(二
氯甲基)胺进行自由基单脱
氯,以良好或优异的收率得到相应的α-(
氯甲基)胺。
