A regioselective synthesis of 2-amino-para-iminonaphthoquinones and 4-amino-1,2-naphthoquinones was described via the substrate-dependent divergent multi-functionalization of β-tetralone with primary and secondary amines under metal-free conditions. This developed strategy features extremely green and mild conditions (O2 as oxidant, ethanol as solvent under ambient temperature), broad substrate scope
