2-(Diazobenzyl)-p-naphthoquinone was synthesized from 2-benzyl-1,4-dimethoxynaphthalene by cerric ammonium nitrate oxidation to 2-benzyl-p-naphthoquinone followed by diazo transfer with tosyl azide. 1,7-Dideoxy-3-demethylprekinamycin was prepared from 1,4-dimethoxynaphthalene by bromination, lithiation, and condensation with acetanthranil to give 2-(2'-N-acetaminobenzoyl)-1,4-dimethoxynaphthalene, which, following deacylation, was subjected to
