Abstract Novel restricted diamines, 2-(1-aminocycloalkan-1-yl)ethylamines 1, were prepared by using Michael addition of ethyl cyclohexylideneacetate 2 and cycloalkylideneacetonitriles 7 with amines. In Michael addition, ester 2 needed high reaction temperature and gave several products, whereas 7 reacted smoothly and gave 2-(1-amino-1-cyclohexyl)acetonitriles 8 in good yield (NH3 85%, MeNH2 89% EtNH2
摘要 利用亚环己基乙酸乙酯2和亚环烷基乙腈7与胺的迈克尔加成反应制备了新型受限二胺2-(1-氨基环烷-1-基)乙胺1。在迈克尔加成中,酯 2 需要高反应温度并得到几种产物,而 7 反应平稳并以良好的产率得到 2-(1-氨基-1-环己基)乙腈 8 (NH3 85%, MeNH2 89% EtNH2 80%) 和容易转化为二胺 1。
