An Atom-Economical Approach to the Synthesis of Potentially Bioactive 2H-Chromenes via CuI-Catalyzed Reactions of Alkyl/Aryl-(E)-(o-Propar­gyloxy)styryl Ketones

A series of potentially bioactive 2 H -chromenes have been synthesized in good yields (60–82%) via CuI-catalyzed reactions of alkyl/aryl-( E )-( o -propargyloxy)styryl ketones in an atom-economical approach.
