Iminium ions are generated by treatment of aminals with succinic anhydride. These iminium ions are trapped by heterocycles, giving the corresponding N-dialkylamino-methyl-substituted heterocycles, which are easily separated from the succinic acid monoamide byproducts by means of an aqueous base wash. The heterocyclic products are obtained in good yield and in a high state of purity without need of
亚胺离子是通过用琥珀酸酐处理缩醛胺而产生的。这些亚胺离子被杂环捕获,得到相应的N-二烷基氨基-甲基取代的杂环,这些杂环可通过碱水洗涤容易地从琥珀酸单酰胺副产物中分离出来。以高收率和高纯度获得杂环产物,而无需重结晶或蒸馏。
