Abstract

The reaction of 3,4‐dihydro‐6,7‐dimethoxyisoquinoline hydrochloride on ethyl vinyl ketone yields two cis and trans benzo[a quinolizinone isomers in variable proportions depending on the pH of the reacting medium. The cis junction isomer can be stabilized and isolated as the β‐propionylethylquinolizinium chloride quaternary salt.
