Abstract

Dialkylpropargyl(3-,Δ′-cyclohexenylpropargyl)amrnonium salts are cyclized in the presence of a base catalyst to give dialkyltetrahydrobenzlfliso-indoline salts in high yields. When the 3-Δ′-cyclohexenylpropargyl and 3 phenylpropargyl groups are both present in the ammonium salt molecule, cyclization proceeds in more than one direction. Salts which contain both the 3-a-naphthylpropargyl and 3-alkenylpropargyl groups are also cyclized in two possible ways.
