Aryl imines of diethyl aminomalonate undergo facile dimerisation to imidazolidines. Heating the imidazolidines at 110° in the presence of N-phenyl maleimide or diethyl azodicarboxylate gives pyrrolidines and triazolidines respectively via a retro 1,3-dipolar cycloaddition.
氨基丙二酸二乙酯的芳亚胺易于二聚为咪唑烷。在N-苯基马来酰亚胺或偶氮二羧酸二乙酯存在下,将咪唑烷在110°加热,分别通过1,3-偶极环加成反应分别得到吡咯烷和三唑烷。
