N-(α-Benzotriazolylalkyl)amines 1a-g serve as stabilized iminium salts for the preparation of allylamines 3a-i in 82-94% yield in two steps starting from benzotriazole, an amine, an aldehyde, and the corresponding vinyl Grignard. Propargylamines 7a-e were also prepared in good yields following the same approach using propargyl Grignard reagents.
N-(α-苯并三唑基烷基)胺 1a-g 用作稳定的亚胺盐,用于从苯并三唑、胺、醛和相应的乙烯基格氏试剂开始分两步以 82-94% 的收率制备烯丙胺 3a-i。使用炔丙基格氏试剂按照相同的方法也以良好的产率制备炔丙基胺7a-e。
