Zusammenfassung: 
An efficient copper-catalyzed cyclization cascade approach towards highly functionalized methylene 4-chromanol and aurone derivatives has been developed from reactions of ynolsvia6-exo-digand 5-exo-digcyclization respectively. The catalysis involves alkyne activationviadiorgano-diselenides and also their regioselective incorporation into the methylene 4-chromanol and aurone derivative core and is an open-air transformation.
