| Abstract: | The ability of the 4-hydroxy-2-butynyl group to participate as  , -unsaturated fragment in base-catalyzed intramolecular cyclization was established. 2,2-Dialkyl-4-hydroxymethylbenzof]isoindolinium and 2,2-dialkyl-4-hydroxymethylisoindolinium salts were obtained by the cyclization of dialkyl(4-hydroxy-2-butynyl)(3-phenylpropargyl)- or dialkyl(4-hydroxy-2-butynyl)(3-alkenylpropargyl)ammonium salts. |
