Abstract

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.
