3-tert-butyl-1-triphenylmethylaziridinone (1e), and 1-(1-adamantyl)-3-tert-butylaziridinone (1g) with some substituted benzylamines and other selected primary amines is described. It emerges from the experimental results that the relative basicity of the amine is a decisive factor in determining regioselectivity in the ring-opening.
四种稳定的 α-内酰胺的开环反应,1-(1-
金刚烷基)-3,3-二甲基
氮丙啶酮 (1a), 3-(1-
金刚烷基)-1-三苯基甲基-
氮丙啶酮 (1d), 3-描述了叔丁基-1-三苯基甲基
氮丙啶酮 (1e) 和 1-(1-
金刚烷基)-3-叔丁基
氮丙啶酮 (1g) 以及一些取代的
苄胺和其他选定的
伯胺。从实验结果可以看出,胺的相对碱性是决定开环区域选择性的决定性因素。
