1-Arylmethyl-2-(bromomethyl)azirdines were converted into the corresponding 2-(aryloxymethyl)aziridines upon treatment with the appropriate potassium phenoxides in DMF/acetone in excellent yields, followed by regioselective ring opening towards N,N-di(arylmethyl)-N-(2-bromo-3-aryloxypropyl)amines using benzyl bromide in acetonitrile. Treatment of the latter β-bromoamines with sodium methoxide afforded
在DMF /丙酮中用适当的苯酚钾处理后,将1-芳基甲基-2-(溴甲基)叠氮基化合物转化为相应的2-(芳氧基甲基)氮丙啶,然后向N,N-二(芳基甲基)区域选择性开环-在苄腈中使用苄基溴的N-(2-溴-3-芳氧基丙基)胺。用甲醇钠处理后一类β-溴胺,除了少量的3-氨基-1-芳氧基-2-甲氧基丙烷异构体外,还提供了所需的2-氨基-1-芳氧基-3-甲氧基丙烷作为主要化合物(49–58%)。数量(9–15%)。
