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
3:3-二取代的2,6-二氧-哌啶衍生物可以通过二取代的乙酸腈或乙酸酯与丙烯腈或丙烯酸酯的迈克尔缩合,然后皂化和闭环来制备。在所描述的氨基烷基化的苯基-二氧代-哌啶中,3-二乙基氨基-乙基-3-苯基-2,6-二氧代-哌啶具有特别强的和特异的副交感神经作用。为了比较,还制备了一些吡咯烷和六亚甲基亚胺化合物。
