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.
通过环己酮,苯乙酮,α-四氢萘酮和樟脑的烯醇锂与醛或酮,胺和苯并三唑的易得加合物的反应,可以以中等至良好的产率制备各种β-氨基酮。当苯并三唑加合物衍生自苯甲醛时,观察到一些非对映选择性。
