3-methoxy-benzanthrones was achieved in two steps by Suzuki–Miyaura coupling and BBr3-promoted Friedel–Crafts acylation under mild conditions with an overall yield of 17–74% and tolerance toward various substrates using commercially available reagents. The competitive mechanism between demethylation and Friedel–Crafts acylation was first rationalized via a deuterium-labelling experiment and DFT calculations. Basic
