INVESTIGATIONS IN THE AREA OF AMINES AND AMMONIUM COMPOUNDS. 237. SYNTHESIS OF 2,2-DIALKYL-4-HYDROXYMETHYLBENZO[<i>f</i>]ISOINDOLINIUM AND 2,2-DIALKYL-4-HYDROXYMETHYLISOINDOLINIUM SALTS
Keywords:
alkenylpropargyl and phenylpropargyl groups, 4-hydroxy-2-butynyl group, 2,2-dialkyl-4-hydroxymethylbenzo[f]isoindolinium and 2,2-dialkyl-4-hydroxymethylisoindolinium salts, base catalysis, cyclizationAbstract
The ability of the 4-hydroxy-2-butynyl group to participate as β,γ-unsaturated fragment in base-catalyzed intramolecular cyclization was established. 2,2-Dialkyl-4-hydroxymethylbenzo[f]-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.
