Abstract

Symmetrical and unsymmetrical 3-halo- or 3-methoxy- substituted 2-dibenzoylamino- 1,4-naphthoquinone analogs were synthesized with an average yield of 45% via sodium hydride promoted bis-acylation of 2-amino-3-chloro-1,4-naphthoquinone, 2-amino-3-bromo-1,4-naphthoquinone and 2-amino-3-methoxy-1,4-naphthoquinone.
Keywords: 1,4-naphthoquinone; imide synthesis; sodium hydride-promoted bis-acylation; unsymmetrical imide 1,4-naphthoquinone; imide synthesis; sodium hydride-promoted bis-acylation; unsymmetrical imide
