Reaction of 2-Methylene-2,3-Dihydroindoles with Acrylamide
Shachkus, A. A.,Degutis, Yu. A.
, p. 740 - 743 (1988)
1,3-Dihydrospiro 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 derivatives were treated with perchloric acid.
