3:3-Disubstituted 2,6-dioxo-piperidine derivatives can be prepared by means of a Michael condensation of disubstituted acetic acid nitriles or acetic acid esters with acrylonitrile or acrylic acid esters, followed by saponification and ring closure. Of the aminoalkylated phenyl-dioxo-piperidines described the 3-diethylamino-ethyl-3-phenyl-2,6-dioxo-piperidine has an especially strong and specific parasympathicolytic
