Chemistry of Heterocyclic Compounds Aims and scope

Abstract

β,γ-Unsaturated ketones (such as cyclohexylideneacetophenone) are formylated with dichloromethyl butyl ether in the presence of anhydrous aluminum chloride. A method has been developed for the synthesis of 3-aryl-substituted 5,6,7,8-tetrahydro-2-benzopyrilium salts unsubstituted in 1 position. The thus-synthesized salts are converted into the corresponding 5,6,7,8-tetrahydroisoquinolines.
