Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work combines comprehensive information on the chemistry of the fluorinated heterocycles. The material has been divided such that the first volume is dedicated to 5-membered fluorinated heterocycles and macrocycles, while the second volume combines data connected with the chemistry of fluorine containing 6-membered heterocycles. Both volumes will be of interest to synthetic organic chemists in general, and particularly for those colleagues working in the fields of heterocyclic-compound chemistry, materials chemistry, medicinal chemistry, and fluorine chemistry. All information is presented and classified clearly to be effective source for broad auditory of chemists. It will be interesting for scientists working in the field of inorganic and coordination chemistry. Fluorinated heterocycles are becoming increasingly important in many areas including the pharmaceutical industry, materials science and agriculture. The presence of fluorine can result in substantial functional changes in the biological as well as physicochemical properties of organic compounds. Incorporation of fluorine into drug molecules can greatly affect their physicochemical properties, such as bond strength, lipophilicity, bioavailability, conformation, electrostatic potential, dipole moment, pKa etc. as well as pharmacokinetic properties, such as tissue distribution, rate of metabolism and pharmacological properties, such as pharmacodynamics and toxicology.

Book excerpt: Chapter 1 reviews recent progress in aryne cycloaddition reactions. The important contributions to the methodology of preparation of arynes in mild reaction conditions are described. Among them, the in-situ generation of arynes via the reaction of ortho- OTMS aryl triflates with fluoride ions is the most applicable. By this method, a variety of arynophiles was employed in the synthesis of nitrogen and oxygen containing 5-7 membered heterocycles. Instructive examples of applications in the total synthesis of natural products (radermachol, (±)-tylophorine, calothrixins, tubingensin B, (+)-hinckdentine A, cossonidine and (methyl)teretifoliones B) are presented. The importance of O-trimethylsilylaryl triflates and fluoride ions methodology for aryne generation is demonstrated in preparation of bioactive molecules and their applicability in medicinal chemistry research. Chapter 2. In addition to thermal reactions, photocycloaddition reactions are a complementary tool in synthetic organic chemistry. The employment of photochemical cycloaddition reactions proceed through different reaction mechanisms and provide access to products which could not be obtained in classical reaction conditions. This chapter is a review of excited state transformations of heterostilbenes to polycyclic structures featuring bicyclo[2.1.1], bicyclo[3.1.0] and bicyclo[3.2.1] moieties. Alongside the main products of these types, often unexpected transformations take place. Some of the photocycloaddition products display interesting biological activity. Chapter 3 reports the results of original scientific research with regards to the application of click reactions in the synthesis of 1,4-disubstituted 1,2,3-triazole conjugates with ribofuranosides and reversed nucleosides. An efficient method for the synthesis of 1,2,3-triazole bridged glycoconjugates with potential biological activity is described and fully supported with the 1H and 13C NMR spectroscopy of novel products. Chapter 4 is a comprehensive review of isocyanide-based cycloaddition reactions. This functionality is highly reactive and participates in many different cycloaddition reactions and annulations. Employment of isocyanide cycloaddition reactions led to the preparation of diverse heterocyclic structures, including asymmetric ones and their applications in medicinal chemistry, in the agricultural, chemical, and supramolecular fields, as well as in the materials sciences. Chapter 5 gives a review of the synthesis of 1,5-benzodiazepine-2,4-dione derivatives via 1,3-dipolar cycloaddition reactions. Functionalization of 1,5-benzodiazepine-2,4-dione by the cycloadditions of nitrilimines, nitrile oxides or azides led to diverse heterocyclic substitutions at positions 1, 3 and 5. Molecular structures of novel products were confirmed by X-ray crystal structure analyses. Chapter 6. Nitrile imines, nitrile oxides and azides were employed in 1,3-dipolar cycloaddition reactions with allyl and propargyl substituted 1,5-benzodiazepine, quinoxaline-2-thiones, benzimidazole and isatin to afford derivatives with heterocylic substituents: pyrazol, isoxazol and triazol. Single crystal X-ray studies of novel products were described, and their biological activity was also reported. Chapter 7. Guanidines are commonly occurring in nature and constituents some natural products with cyclic structures. Various cycloaddition reactions leading towards cyclic guanidine structures were reviewed. The review also summarized cycloaddition reactions in which functionalized guanidines were acting as the reaction partners.

Download or read book Diradicaloids written by Jishan Wu and published by CRC Press. This book was released on 2022-04-01 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: π-Conjugated molecules with an even number of π-electrons usually have a closed-shell ground state. However, recent studies have demonstrated that a certain type of molecules could show open-shell singlet ground state and display diradical-like (diradicaloid) behavior. Their electronic structure can be understood in terms of the “diradical character” and “aromaticity” concepts. They display very different electronic properties from traditional closed-shell π-conjugated molecules and could be used as next-generation molecular materials. This book provides a comprehensive review on the chemistry, physics, and material applications of open-shell singlet diradicaloids. Particularly, it elaborates the fundamental structure–diradical character–electronic property relationships both theoretically and experimentally. The book has been written by leading scientists in the field from Japan, Germany, Spain, Italy, China, and Singapore.

Available in PDF, EPUB and Kindle. Book excerpt: The book represents the most complete description of the scientific results obtained on a photochemical experiment described 110 years ago by the Italian scientist Emanuele Paternò. This detailed that the photochemical reaction between a carbonyl compound and an alkene gives a corresponding oxetane. This oxetane ring is present in several naturally occurring compounds and bioactive compounds, and can be obtained with high regio- and stereoselectivity.

Available in PDF, EPUB and Kindle. Book excerpt: Acetylene systems present a new route to cyclic compounds as an alternative to more traditional methods employed in classical organic chemistry. The synthesis of cyclic structures based on acetylene systems has important applications in the formation of nanostructures, naturally occurring compounds and chemosensory materials for the design of nonlinear optics, electronic and photonic devices. Alkynes in Cycloadditions presents a modern review of regioselective synthesis of aromatic and non-aromatic carbocyclic and heterocyclic ring systems based primarily on [2+2+2] and [4+2] cycloadditions, and other reactions of acetylenic units including enediynes and enyne-allenes. Topics covered include: New strategies for the formation of aromatic and polynuclear hydrocarbons based on (Z)-hex-3-en-1,5-diyne and (Z)-hepta-1,2,4-triene-6-yne blocks. One-step synthesis of benzene derivatives, β-substituted naphthalenes and acenes by the cycloaromatization of enediynes and enyne-allenes by Bergman, Myers-Saito and Shmittel. Mechanisms of cycloaromatization resulting in the formation of fulvene and indene systems. Heterocyclization involving enyne-carbodiimides. New achievements in classical cycloaddition reactions such as the Diels-Alder condensation with acetylenic dienophiles and [2+2] cycloadditions with acetylene components Alkynes in Cycloadditions presents a comprehensive summary of the literature on methods for the synthesis of ring systems from acetylenes for academic researchers working in the fields of organic synthesis, physical organic chemistry, organometallic chemistry, catalysis, materials science, nanomaterials and biochemistry.
