CYCLIZATION OF DIALKYL-(4-HYDROXY-2-BUTYNYL)(3-ALKENYL-PROPARGYL)AMMONIUM SALTS AND RECYCLIZATION OF THE 2,2-DIALKYL-4-HYDROXYMETHYLISOINDOLINIUM SALTS OBTAINED
Keywords:
4-hydroxy-2-butynyl group, dialkyl(3-alkenylpropargyl)-(4-hydroxybutyn-2-yl)ammonium salts, (1,3-dihydro-4-isobenzofuranylmethyl)dialkylamines, base catalysis, recyclization, cyclizationAbstract
2,2-Dialkyl-4-hydroxymethylisoindolinium chlorides, like benzisoindolinium salts, readily undergo intramolecular recyclization under conditions of aqueous alkaline decomposition, comprising fission of the isoindolinium ring and formation of a dihydrofuran ring leading to (1,3-dihydro-4-isobenzofuranylmethyl)dialkylamines.
