Abstract

Abstract Durch oxidative Kupplung des Naphthols 37b wurde der potentielle Naturstoff 7, 7′-Dimethyl-6, 6′-bijuglon (5) und in kleinerer Ausbeute Isodiospyrin (21) erhalten. Regiospezifische Synthesen von 5, Elliptinon (10) und 6, 6′-Bijuglon (45a) gelangen durch Phenoloxidation geeignet substituierter p-Chlornaphthole.
