Abstract

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.
