The invention also provides a method for synthesis of a multi-quinone compound including reacting a hydroxyquinone anion with a first quinone possessing a first directing group at a C-2 of the first quinone and a second directing group at a C-3 of the first quinone and obtaining a biquinone having one of the first and second directing groups at a C-3 of a first quinone monomer and a hydroxyl group at a C-3′ of a second quinone monomer. The biquinone can be further reacted to obtain various biquinone derivatives or with a second hydroxyquinone anion to obtain trimeric quinone derivatives, including trimeric naphthoquinone derivatives. The biquinones and trimeric quinones of this invention demonstrate antiviral activity and can be used to treat viral infections, particularly HIV infections.
