Abstract
Abstract1,3-Dihydrospiro[2H-indolo-2,2′-piperidine] derivatives were obtained by the reaction of 2-methylene-2,3-dihydro-1H-indole derivatives with acrylamide in proton-containing solvents. 2-(3-Carbamoylpropyl)-3H-indolium perchlorates were formed when the 1,3-dihydrospiro[2H-indolo-2,2′-piperidine] derivatives were treated with perchloric acid.
