Derivatives of 1,3-dihydrospiro<2H-indole-2,2'-pyrrolidine> were synthesized by the reaction of 2-methylene-2,3-dihydro-1H-indoles with α-iodoacetamide.Treatment of the products with alkyl iodides in the presence of potassium hydroxide gave 1'-substituted spiroindole-2,2'-pyrrolidines.The 1,3-dihydrospiro<2H-indole-2,2'-pyrrolidines> were converted by the action of perchloric acid into 2-(2-carbamoylethyl)-3H-indolium perchlorates.
