3-Methoxycarbonylcatechol effectively underwent two-way regiocontrolled coupling with indoles an -benzoquinone intermediate, resulting from phenyliodine(III) diacetate oxidation, to generate 4-adducts or 5-adducts with or without BF·EtO in a one-pot manner. DFT calculations confirmed the obtained regioselectivities.
