Facile Access to Novel 1,4-Dihydroxynapththalene-2,3-dicarboximides and Heterofused Analogs

A variety of novel 1,4-dihydroxynaphthalene-2,3-dicarboximides and heterofused analogs were prepared by a convenient one-pot base-catalyzed condensation of N-substituted succinimides with aromatic ortho diester derivatives.
