give cyclobutanes, whereas addition to enamines derived from cyclic ketones produces quaternary salts. It is proposed that these salts result from an intramolecular reaction of initially formed alkylation products. Ethyl β-methylaminocrotonate gives a pyrroline derivative, in which case the initial alkylation product undergoes an intramolecular condensation with subsequent hydrogen chloride elimination
已显示将α-氯丙烯腈加到醛烯胺中可得到环丁烷,而将烯丙基环胺衍生自烯胺则可生成季盐。提出这些盐是由最初形成的烷基化产物的分子内反应产生的。β-甲基氨基巴豆酸乙酯产生吡咯啉衍生物,在这种情况下,初始烷基化产物进行分子内缩合,随后消除氯化氢。二烯胺1-N-吗啉代-1,3-丁二烯通过狄尔斯-阿尔德反应加到α-氯丙烯腈中。
