COPPER(I) IODIDE-PROMOTED CYCLIZATION OF N-2-HALOARYL-AND N-(2-HALOARYL)METHYL-SUBSTITUTED ENAMINONES

Abstract
Anions derived from the title compounds are found to undergo smooth cyclization to give indoles and dihydroisoquinolines, respectively, on being heated in the presence of copper(I) iodide in hexamethylphosphoric triamide.
