Recently described results concerning in particular the reaction between N-isopropylidene-cyclohexylamine 1b and methyl acrylate were reinvestigated, due to the claim that only N-alkylation takes place. Our results show that in fact several reactions do occur, particularly the C-alkylation yielding iminoesters 3b and 5, but that no N-alkylation takes place. The principal side reaction is the “aldo
由于声称仅发生N-烷基化,因此重新研究了最近描述的,特别是关于N-异亚丙基-环己胺1b与丙烯酸甲酯之间的反应的结果。我们的结果表明,实际上确实发生了几种反应,特别是C-烷基化反应生成亚氨基酯3b和5,但没有发生N-烷基化反应。主要的副反应是亚胺1b的“醛基化-巴豆化” ,生成异亚丙基丙酮,亚胺8和环己胺,后者继而加成丙烯酸甲酯,得到β-氨基酯9。
