Abstract
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.
