Article abstract of DOI:10.1016/0040-4039(95)00295-N

Direct displacement of chlorine atoms by alkoxy groups in 2,3-disubstituted juglones (5-hydroxy-1,4-naphthoquinones), naphthazarines (5,8-dihydroxy-1,4-naphthoquinones), and quinizarines (1,4-dihydroxy-9,10-anthraquinones) is generally ineffective, howeve
