Imines of diethyl aminomalonates slowly dimerise to imidazolidines in ethanol or methylene chloride at 40 deg C, but cycloaddition to other imines does not occur.Imines of glycine, alanine and phenylglycine methyl esters undergo rapid regio- and stereo-sp

Aryl imines of diethyl aminomalonate undergo facile dimerisation to imidazolidines.Heating the imidazolidines at 110 deg C in the presence of N-phenyl maleimide or diethyl azodicarboxylate gives pyrrolidines and triazolidines respectively via a retro 1,3-dipolar cycloaddition.
