19 Dec 2017 In this two-part review (Part 2 to be published in Progress in Heterocyclic Chemistry, Volume 25), recent advances in the synthesis of quinoxalines are reviewed. Medicinal compounds containing a quinoxaline moiety are also covered. The review covers condensations of 1,2-diaminoarenes, condensations

ABSTRACT. The objective of present research work is to provide green technique for synthesis of 2,3-diphenyl quinoxaline. Quinoxaline derivatives are well known in the pharmaceutical industry and have been shown to possess a broad spectrum of biological activities. Highly efficient and simple methods have been
Quinoxaline derivatives are an important class of heterocycle compounds, where N replaces some carbon atoms in the ring of naphthalene. Its molecular formula is C8H6N2, formed by the fusion of two aromatic rings, benzene and pyrazine. It is rare in natural state, but their synthesis is easy to perform. In this review the
The synthesis of quinoxalines has been intensively studied in the past, especially because of the diverse biological activities ascribed to many representatives of this class of compounds. Consequently, a large variety of synthetic methods for the synthesis of functionalized quinoxalines has been reported in literature.
