Synthesis and characterization of novel unsymmetrical and symmetrical 3-halo- or 3-methoxy-substituted 2-dibenzoylamino-1,4-naphthoquinone derivatives

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. © 2013 by the authors.
