Abstract

The intramolecular thermal cyclization of dimethylallylbenzylammonium bromide and dimethylallyl(α-methylnaphthyl)ammonium chloride led to the formation of 2,2-dimethyl-7,7a-dihydro-3a,6-vinyleneisoindolinium bromide and 2,2-dimethyl-7,7a-dihydro-3a,6-vinyleneisoindolinium bromide and 2,2-dimethyl-7,7a-dihydro-3a,6-vinylene-4,5-benzisoindolinium chloride, respectively, the alkaline cleavage of which leads to 3-methyl-4-dimethylaminoinethylstyrene and 2-methyl-4-vinyl-1-dimethylaminomethylnaphthalene.
