We report a bioinspired approach for the regioselective construction of both aromatic C–O and C–N bonds through the dehydrogenative coupling of phenols and aliphatic amines. Mechanistically, the process hinges on the ortho-oxygenation of phenols to ortho-quinones followed by aromatic C–N bond formation through a condensation/redox isomerization cascade. Overall, the process enables the regioselective
