Book excerpt: This book reviews the fundamental aspects of quinoxaline chemistry: synthesis, reactions, mechanisms, structure, properties, and uses. The first four chapters present a survey of the developments in quinoxaline chemistry since the publication of the monograph on “Condensed Pyrazines” by Cheeseman and Cookson in 1979. These chapters give comprehensive coverage of all the methods of the synthesis of quinoxalines and the important quinoxaline-containing ring systems such as thiazolo[3,4-a]-, pyrrolo[1,2-a]-, and imidazo[1,5-a]quinoxalines. Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement). This book is of interest to researchers in the fields of heterocyclic and synthetic organic chemistry.

This book was released on 2024-02-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen-containing heterocycles belong to the most versatile and important compounds for medicinal chemistry and sustainable and advanced materials. Around 60 % of FDA-approved unique small molecule drugs incorporate a nitrogen heterocycle. N-heterocyclic compounds are essential components of organic light-emitting diodes and organic solar cells. Quinoxalines are a class of heterocyclic compounds accessible by straightforward syntheses, present in commercially available drugs and optoelectronic architectures. In this work, quinoxaline-containing compounds were synthesized and analyzed regarding their potential uses in biology and materials science, focusing on nitrogen-rich and dimeric quinoxalines. Various tetrazolo[1,5-a]quinoxalines were synthesized and converted to 1,2,3-triazoloquinoxalines and novel triazoloimidazoquinoxalines via a modified CuAAC procedure. A previously unknown copper-catalyzed denitrogenative annulation process was described in this context. As tankyrase inhibitors, substituted tetrazolo[1,5-a]quinoxaline derivatives were assembled and tested in biological studies. Moreover, the synthesis of quinoxaline dimers and metal complexation of selected 1,2,3-triazoloquinoxalines was investigated. Donor-acceptor emitter structures were assembled employing suitable tetrazolo [1,5-a]quinoxalines and 1,2,3-triazoloquinoxalines and their emissive properties were explored, highlighting the influence of the direction of the triazole linker on delayed fluorescence.

Available in PDF, EPUB and Kindle. Book excerpt: In the second part of this two-part review (for Part 1 see V.A. Mamedov, A. Nataliya, N.A. Zhukova, Prog. Heterocycl. Chem. 2012, 24, 55), recent advances in the synthesis of quinoxalines are reviewed. Syntheses that start from pyrazine fragments and from benzenoid units are discussed. The review covers quinoxaline synthesis starting from anilines and derivatives of anilines, from nitroarenes, from other heterocycles, including benzimidazoles, benzodiazepines, and from fragments that contain neither a pyrazine ring nor a benzene ring, for example, epoxides and azirines, pyrrolidin-3-ones and piperidin-3-ones, γ-butyrolactones, pyran-2,3-diones, and 4-hydroxythiazolidines, amongst others.
