Abstract

Quinoxaline is a core constituent of many pharmaceuticals as well as agrochemicals. 1 Quinoxaline ring is also found in antibiotics such as echinomycin, leromycin, and actinomycin. 2 In addition to this, quinoxaline ring is a part of several bioactive natural products. Some of the quinoxaline derivatives were found to exhibit broad spectrum of biological activity, 1c while the other derivatives of quinoxaline have found wide application in dyes, 3a efficient electroluminescent ...
