Similarly to N-benzylpiperidine and -pyrrolidine, N-benzylazetidine underwent RuO4-catalyzed oxidation by attack at both types of N-methylene C-H bonds: endocyclic and exocyclic (benzylic). If the reaction is performed in the presence of cyanide, α-aminonitriles were obtained instead of amides. The regioselectivity (endocyclic/exocyclic) decreased constantly with the decrease of the azacycle size,
与 N-苄基

吡咯烷类似,N-苄基氮杂
环丁烷通过攻击两种类型的 N-亚甲基 CH 键:内环和外环(苄基)进行 RuO4 催化氧化。如果反应在
氰化物存在下进行,则得到 α-
氨基腈而不是酰胺。区域选择性(内环/外环)随着氮杂环尺寸的减小而不断降低,从大约 2(对于 N-苄基
哌啶)到大约 0.6(对于 N-苄基
哌啶)。Nbenzylaziridine 的区域选择性最高,仅产生苄基官能化产物。与
