Abstract
The review is devoted base-catalyzed intramolecular cyclization of ammonium salts containing β,γ-unsaturated groups alongside with various enyne fragments. This process results in the formation of polynuclear isoindolinium salts and in the transformation (recyclization) of those containing the hydroxymethyl group at the position 4 in the aromatic ring.
