摘要

A wide variety of β-amino ketones are prepared in moderate to good yields by the reaction of the lithium enolates of cyclohexanone, acetophenone, α-tetralone and camphor with the readily available adducts from an aldehyde or ketone, an amine and benzotriazole. Some diastereoselectivity is observed when the benzotriazole adduct is derived from benzaldehyde.
