  • Chapter Two Recent Advances in the Synthesis of Piperidines:
           Functionalization of Preexisting Ring Systems

      The present review focuses on strategies for the construction of piperidines which have appeared in the literature since 2003 through mid-2017. In a preceding chapter (2017AHC191), we summarized synthetic methods involving the construction of the piperidine ring from essentially acyclic starting materials in an intra- or intermolecular manner. The present chapter aims at giving a general overview of decoration or modification of previously generated pyridines or piperidines. The hydrogenation of preformed pyridine or pyridinium rings and introduction of substituents into fully saturated piperidines as well as ring expansion of pyrrolidines to piperidines are the most prevalent methods.

      Indazoles (azaindoles) are heterocyclic compounds structurally related to indoles and can be viewed as indole isosteres. The indazole moiety is a 10-π electron aromatic heterocyclic system. Like the pyrazole, indazole resembles both pyridine and pyrrole and its reactivity reflects this. In this chapter, we have updated the synthesis of indazoles and their reactivity we focus attention on the synthesis this class of compounds.

  • Chapter Four The Chemistry of Sulfur-Containing [5,5]-Fused Ring Systems
           With a Bridgehead Nitrogen
    • Authors: Frédéric Buron; Marie-Aude Hiebel; Jean-Yves Mérour; Karen Plé; Sylvain Routier
      Pages: 301 - 356
      Abstract: Publication date: 2018

      Author(s): Frédéric Buron, Marie-Aude Hiebel, Jean-Yves Mérour, Karen Plé, Sylvain Routier
      This review deals with the synthesis and chemical functionalization of sulfur- and nitrogen-containing [5,5]-fused ring systems with one nitrogen atom in the bridgehead position and a fixed sulfur atom. With up to three additional nitrogen atoms, there are 21 possible ring structures. Of these, only nine are found reported in the literature in more than an anecdotal manner. These scaffolds play an important role in the design and synthesis of biologically active molecules, and the chemistry of these compounds is rich and varied. Their use in medicinal chemistry has grown exponentially in the past few years, especially in the context of molecular diversity. These scaffolds are also bioisosters of indolizines, imidazopyridazines, and their derivatives.

      Author(s): Taku Shoji, Shunji Ito
      Azulene derivatives having heteroaryl substituents have been prepared, for the purpose of application to material sciences, by utilizing their unique properties. These derivatives have been synthesized by various methods including transition metal-catalyzed coupling, electrophilic substitution, and cyclization reactions. In this review, we describe recent developments in the synthesis of heteroarylazulenes and hetero-fused azulenes, as well as their reactivity and physical properties.

  • Recent Developments in the Chemistry of Pyrazoles
    • Authors: Andrew W. Brown
      Abstract: Publication date: Available online 28 March 2018
      Source:Advances in Heterocyclic Chemistry
      Author(s): Andrew W. Brown
      The pyrazole motif has been found to be amenable to extensive, wide-ranging applications. A long-standing history of success has been achieved in the pharmaceutical field. More recent exploits have seen exciting developments in the areas of metal–organic frameworks, liquid crystals, and electroluminescence to name but a few. Such diverse applications have resulted in a demand for access to evermore complex examples of this diazole, which has driven synthetic chemists to develop a multitude of novel methods. In particular, modern methods have strived to overcome limitations in regioselectivity that are associated with classical methods. They have also sought to install significant molecular complexity within a single transformation to avoid lengthy functionalization sequences. As highlighted in this review, covering advances in the synthesis and application of pyrazoles in the past two decades, significant progress has been made in the use of metal catalysis, cycloaddition reactions, and multicomponent reactions for the construction of 5-membered heterocycles.

      Author(s): Yuri Shafran, Tatiana Glukhareva, Wim Dehaen, Vasiliy Bakulev
      The chapter is focused on the synthesis of 1,2,3-thiadiazoles including Hurd–Mori reaction, Wolff approach, and oxidative cyclization of hydrazones bearing thioamide group. It also contains data on the synthesis of fused 1,2,3-thiadiazoles and those linearly connected to other heterocycles. Moreover, a short overview of biological properties is given in a separate section. The data on the chemical properties are limited in the current review to ring-cleavage reactions and rearrangements of 1,2,3-thiadiazoles to other heterocyclic compounds. An analysis of 1,2,3-thiadiazole chemistry for the period 2003–17 is presented. Materials covered in earlier periods are included when they are appropriate for discussions.

      Abstract: Publication date: Available online 23 December 2017
      Source:Advances in Heterocyclic Chemistry
      Author(s): Bahareh Talaei, Majid M. Heravi
      Diketene is an ideal molecule for use in many organic transformations, since it possesses electrophilic and nucleophilic sites which react with numerous functional groups. Diketene is mostly used as the common starting material for structurally diverse mono-, spiro-, and fused six-membered heterocycles such as lactones, pyrans, pyridines, quinolines, isoquinolines, oxazine, quinoxalines, benzothiazinone, 1,4-thiazidines, and oxazinonethione.

  • Tautomerism and Structure of Azoles: Nuclear Magnetic Resonance
           Spectroscopy
    • Authors: Lyudmila I. Larina
      Abstract: Publication date: Available online 5 August 2017
      Source:Advances in Heterocyclic Chemistry
      Author(s): Lyudmila I. Larina
      This review provides comprehensive data (from the author's work and the literature) on tautomerism of pyrazoles, imidazoles, 1,2,3- and 1,2,4-triazoles, tetrazoles, benzimidazoles, benzimidazolones, benzotriazoles, and related compounds by multinuclear 1H, 13C, 15N nuclear magnetic resonance (NMR) spectroscopy. Emphasis is given to studies of azoles by multinuclear dynamic NMR spectroscopy because prototropic transformations of almost all azoles in solution proceed so quickly. Quantum-chemical investigations of tautomeric azoles are covered in detail. Critical analysis of literature data on the tautomerism of azoles is presented. Theoretical studies of structure and reactivity of azoles are most intriguing because correct interpretation of their chemical behavior and biological activity depends on an understanding the factors determining relative stability of their tautomers. 15N NMR spectroscopy is the most reliable and fast technique for structural and tautomeric determination of nitrogen-containing heteroaromatic compounds.

      This chapter presents the synthesis of heterocycles with a hypervalent, pentacoordinated phosphorus atom. It is divided into two sections. The first is devoted to the preparation of pentavalent, pentacoordinated, hypervalent monocyclic phosphoranes, and their selected interconversions. The second section, concerning bicyclic heterocycles, describes the synthesis and reactivity of all kinds of bicyclic phosphoranes. The phenomenon of chirality for this group of organophosphorus derivatives is also briefly discussed.

      Thiophene-based compounds have acquired increasing importance in materials science and technology, owing to their multiple functional properties, chemical robustness, and versatility. Research studies involving thiophene-based materials are highly interdisciplinary and range from organic electronics, in which the semiconducting properties of these materials are exploited in devices such as thin film field-effect transistors and solar cells, to bioimaging, in which their optical properties are exploited to monitor biological events involving proteins and DNA. Since all fields are concerned with the synthesis of new molecular structures, this chapter also deals with the most recent advances in the synthesis of oligo- and polythiophenes.

      Five- and six-membered heteroaromatic rings and their benzo-fused homologues are well established as important structural elements in drug design and are well represented in approved drugs. The key properties of these heterocycles that are of interest to medicinal chemists include lipophilicity, pK a, aromaticity, ionization potential, H-bond acceptor, and H-bond donor (NH, OH, CH) capability, electron withdrawing effects, dipole values, and bond angles. The judicious and productive application of azoles and azines in drug design requires an understanding of the intrinsic physical chemical properties of the individual heterocycles and how these interact with substituents. In this article, the key properties of azole and azine heterocycles are summarized followed by a synopsis of applications where some of these factors play a role in drug–target interactions and/or potency.

  • Synthesis of Heterocycles From Amidrazones
    • Authors: A.A. Aly; M. Ramadan; H.M. Fatthy
      Abstract: Publication date: Available online 29 December 2016

      Amidrazones have the structure R1NC(R2)=NNHR3. The ease of forming CN and CN bonds is reflected in their extensive use for the preparation of heterocycles. While the terminal nitrogen atom of the hydrazone moiety in amidrazones (CNNH2) is the most powerful nucleophilic center, the other two nitrogen atoms can also act as nucleophiles and thus complete cyclization processes. In this chapter, we update the utility of amidrazones in heterocycles synthesis.

      4-Methyleneoxetan-2-one (Diketene or DK) consists of a four-membered lactone ring adjacent to a methylene function. It can be used as a versatile precursor for the syntheses of wide range of heterocycles including fused and spiral biheterocycles. In this chapter, we try to cover the structural features and reactivity of DK, and underscore its applications as a flexible and useful synthon in the syntheses of four- and five-membered heterocycles as well as a wide variety of fused or spiro heterocycles. This chapter as part 1 is divided in accordance with the ring sizes and subdivided according to types, numbers, and arrangements of heteroatoms.

  • 2-Pyridone Methides (2-Methylene-1,2-dihydropyridines) and Benzo-Fused
           Analogs—Part 1: Synthesis
    • Authors: Fischer
      Abstract: Publication date: Available online 30 August 2016

      Author(s): G. Fischer
      The review (Part 1) deals with the synthesis of 2-pyridone methides and benzo-fused analogs. Methides that are unsubstituted at the nitrogen atom are mainly synthesized from the corresponding pyridine bases by reactions at o- or α-positions, from N-oxides or by ring formation or transformation. N-Substituted so-called anhydrobases mostly originate from quaternary salts either by deprotonation or by reactions at o- or α-positions.
