Abstract: The acid catalyzed cyclization of Benzyl substituted Octahydroisoquinoline results in the formation of a major product, N-Formyl Dextromethorphan and a minor product, one of the morphinan derivatives, which is formed via the mechanism of Super electrophiles. Excess Phosphoric acid acts as an electrophile and leads to the formation of a novel minor product but has a significant existence and can be isolated using Column Chromatography at the later stages.
