N-2-[(1-R-Cyclopropyl)methyl]prop-2-enyl}-N,N-dimethylamines were prepared in 80-90% yields by the reaction (5 h, 23-25 C) of propargylamines R-C=C-CH2NMe2 (where R = alkyl, Ph) with a system of reactants CH2I2-Et3Al taken in the molar ratio [propargylamine]: [Et3Al]: [CH2I2] = 1: 6: 6. In the case of phenyl-substituted propargyl- amine, N-(1-[(1-phenylcyclopropyl)methyl]cyclopropyl}methyl)-N,N-dimethylamine is selectively formed in 76% yield upon the elongation of the reaction time to 4 days.
通过丙炔胺 R-C=C-CH2NMe2(其中 R = 烷基,Ph)与反应物 CH2I2-Et3Al 体系以 [丙炔胺] 的摩尔比进行反应(5 h,23-25 C),制备了 N-2-[(1-R-环丙基)甲基]丙-2-烯基}-N,N-二甲基胺,收率为 80-90%:[Et3Al]:[对于苯基取代的丙炔基胺,当反应时间延长至 4 天时,可选择性地生成 N-(1-[(1-苯基环丙基)甲基]环丙基}甲基)-N,N-二甲胺,收率为 76%。
