  • Chapter 1 Semi-Conjugated Heteroaromatic Rings
    • Authors: Christopher A. Ramsden
      Pages: 1 - 25
      Abstract: Publication date: 2016
      Source:Progress in Heterocyclic Chemistry, Volume 28
      Author(s): Christopher A. Ramsden
      A systematic analysis of the connectivity of heteroatoms in heterocyclic mesomeric betaines (HMBs) reveals three main classes: conjugated HMBs, cross-conjugated HMBs, and the previously unrecognized semi-conjugated HMBs. The defining features of each class are discussed with particular emphasis on semi-conjugated systems.

      β-Lactams represent versatile building blocks in heterocyclic chemistry. This chapter covers recent methodologies for the preparation of functionalized six-membered and three-membered azaheterocycles by ring transformation of azetidin-2-ones. Furthermore, emerging topics including the synthesis of biologically relevant C-fused bicyclic β-lactams and β-lactam-based hybrids are discussed.

      The reactions and syntheses of pyrroles, indoles, isatins, carbazoles, and related fused heterocyclic ring systems from the year 2015 are reviewed. Pyrroles and indoles are treated in separate sections with the ring-forming reactions discussed by intramolecular or intermolecular bond disconnection. Other sections include nucleophilic, electrophilic, or radical reactivity of the parent rings; C–H functionalization/organometallic reactions; reactions of side chains; and examples in total synthesis.

      Found in natural products and frequently used as flavoring agents or as building blocks for pharmaceuticals, diazines and their benzo derivatives possess a diverse set of properties, allowing a broad range of applications, spanning from medicinal chemistry to electrochemistry. New diazine-based natural products continue to be isolated and studied. In addition, new syntheses, reactions, and applications of diazine-based compounds are reported every year. Recent advances in the development of new preparations, reactions, and applications of diazines and their benzo derivatives as well as the discovery of new diazine-based natural products, published in the literature in 2014, are discussed in this review.

      Pages: 493 - 521
      Abstract: Publication date: 2016
      Source:Progress in Heterocyclic Chemistry, Volume 28
      Author(s): Pierre Audebert, Gilles Clavier, Clémence Allain
      This chapter describes and resumes the different works that provided real advances in the field of aromatic heterocycles featuring several nitrogen atoms, in the authors' opinion, during the year 2015. It is divided into three main sections, one devoted to triazines, separating the symmetrical triazines (1,3,5-triazines or s-triazines) from the unsymmetrical ones (1,2,4-triazines or a-triazines). A second part is devoted to tetrazines, especially featuring the abundant and more investigated 1,2,4,5-tetrazines or s-tetrazines. Finally, a last shorter section is devoted to less common and higher order rings like heptazines, fused purines, pteridines, and so on. While emphasizing on the original and new synthetic methods and reactions, the chapter also relates briefly the biological applications of these compounds, and also the fast-rising applications in the field of active molecular materials.

      This chapter aims to provide an overview of the key synthetic methods, reactions, and applications reported in 2015 in the area of seven-membered heterocyclic compounds. Most of the focus has centered on benzo-derivatives containing at least one N atom, and has been driven by the search for new heterocycles with biological activity and the total synthesis of natural products. New synthetic methods of interest have included transition metal-catalyzed, dipolar cycloaddition, cascade and C-H functionalization processes. The increasing number of reports on the chemistry of heterocyclic compounds containing four or five N, O, or S atoms is also covered.
