Abstract

Quaternary ammonium salts containing a 3-α-naphthylpropargyl group together with an allyl-type group undergo base-catalyzed intramolecular diene cyclization to give 2,2-dialkylnaphtha[f]-3a,4-dihydroisoindolinium salts. Cleavage of the latter with aqueous alkali gives dialkylaminomethylphenanthrenes.
