A variety of N-arylcyclopropylamines has been prepared in one step, by the Pd2(dba)3/BINAP/NaOtBu-catalyzed amination of an aryl bromide with cyclopropylamine. Compounds bearing the N-aryl substitutent (phenyl, 4-methylphenyl, 2-methoxyphenyl, 3-methoxyphenyl, 4-chlorophenyl, 1-napthyl, 9-anthryl, 9-phenanthryl, and 3-pyridyl) were prepared in isolated yields ranging from 43 to 99%. Overall, this chemistry
通过Pd 2(dba)3 / BINAP / NaO t Bu催化的芳基溴化物与环丙胺的胺化反应,一步制得了各种N-芳基环丙胺。制备具有N-芳基取代基的化合物(苯基,4-甲基苯基,2-甲氧基苯基,3-甲氧基苯基,4-氯苯基,1-萘基,9-蒽基,9-菲基和3-吡啶基),分离的产率为43至99%。总的来说,这种化学方法比以前的合成这类化合物的多步骤方法有了很大的改进。
