Описание: This volume provides an overview of recent developments and scope in the use of flow chemistry in relevance to heterocyclic synthesis. The heterocyclic ring is the most prominent structural motif in the vast majority of natural products as well as pharmaceutical compounds since this facilitates tuneable interactions with the biological target besides conferring a degree of structural and metabolic stability. In recent times, flow chemistry has heralded a paradigm shift in organic synthesis as it offers several unique advantages over conventional methods like drastic acceleration of sluggish transformations, enhanced yields, cleaner reactions etc and is gradually gaining a lot of attention among organic chemist worldwide. Given the importance of heterocycles in natural products, medicinal chemistry and pharmaceuticals, this is a well warranted volume and complements the previous volume of Topics in Organometallic Chemistry ‘Organometallic Flow Chemistry’. This volume offers a versatile overview of the topic, besides discussing the recent progress in the flourishing area of flow chemistry in relevance to heterocyclic chemistry; it will also help researchers to better understand the chemistry behind these reactions. This in turn provides a platform for future innovations towards the designing of novel transformations under continuous flow. Thus, this volume will appeal to both the novices in this field as well as to experts in academia and industry.
Описание: * Clearly structured with proven systematic: The ordering system according to the ring size of the heterocycles will remain. * New: The contents of the important chapter "Problems and their Solutions" will be completely re-structured and enhanced with up-to-date scientific exercises. A great tool for self-testing and exams.

The Chemistry of Heterocycles: Structure, Activity, and Applications provides a detailed guide to the chemistry, behavior and potential of these important structures. Beginning with an introduction on the topic, the book presents a practical guide to international nomenclature, including discussions of fused ring systems, heteroatoms with abnormal valences, and bridged, spiro and polycyclic heterocycles. Three membered heterocycles are then the focus, along with their thermodynamic properties and importance in natural products, medicines, materials, and their unique aspects, such as strain, basicity and reactivity.
Additional chapters cover 100 key heterocycle structures, from Azetidines, Pyrroles and Pyridines, to Benzoxepines and Oxocanes. Final chapters explore cutting-edge advances in the development of phosphorus and selenium based heterocycles.
Provides clear, detailed information on each heterocyclic group, including structural features, such as ring strain, basicity, synthesis and reactivity towards electrophilic and nucleophilic reagents
Highlights the latest advances in the field, including phosphorous and selenium-based heterocycles that are supported by numerous illustrations
Includes details of functionalized heterocycles used as synthons for the construction of various arenes and heteroarenes
Описание: A comprehensive reference on the synthetic chemistry of cycloaddition reactions Dipolar cycloaddion reactions have found many useful applications in chemistry, particularly with respect to the synthesis of compounds with new chiral centers. Such asymmetric syntheses have a growing importance in the pharmaceutical and agricultural industries with respect to the preparation of chiral drugs and natural products. This much-needed volume updates the popular 1984 edition with advances made over the last twenty years in cycloaddition reactions. While the 1984 volume focused on theory, structure, reactivities, and selectivities, the new volume is geared toward synthetic applications. Both carbonyl ylides and nitronates, important members of the 1,3-dipole family that were not reviewed previously, are now included. Also, beyond the capability of the 1,3-dipolar cycloadditon reaction to produce heterocycles, the ability of heteroatom-containing cycloadducts to transform into a variety of other functionalized organic molecules, cylclic or acyclic, and the ability of many 1,3-dipolar cycloadditions to generate rings containing several contiguous stereocenters in one synthetic operation is discussed. Volume 59 provides the only comprehensive reference on the market detailing the synthetic chemistry of cycloaddition reactions.

Описание:
Heterocycles are ubiquitously present in nature and occupy a unique place in organic chemistry as they are part of the DNA and haemoglobin that make the life possible.
The Chemistry of HeterocyclesVolume 1 covers an introduction to the topic, followed by a chapter on the nomenclature of all classes of isolated, fused and polycyclic heterocycles. The third chapter delineates the highly strained three membered N, O and S containing aromatic and non-aromatic heterocycles with one and more than one similar and dissimilar heteroatom. The four-membered heterocycles are abundantly present in various natural and synthetic products of pharmacological importance. This chapter describes the natural abundance, synthesis, chemical reactivity, structural features and their medicinal importance. This class of compounds are present as sub-structures in penicillin and cytotoxic Taxol. Lastly, a chapter on the natural abundance, synthesis, chemical reactivity and pharmacological importance of 5-membered heterocycles with N, O, S heteroatom is covered. The chemistry of heterocycles with mixed heteroatom such as, N-S, N-O, N-S etc. is also described.
Gives in-depth, clear information about various systems of nomenclature along with widely acceptable IUPAC system for naming various classes of heterocycles
Provides complete information about natural occurrences, synthesis, chemical reactivity, pharmacological importance of heterocycles and their application in material science
Highly relevant for graduate students and researchers, providing updated information about various isolated and fused N, O and, S containing heterocycles
Описание: Elizabeth Gaskell`s Life of Charlotte Bronte (1857) is a pioneering biography of one great Victorian woman novelist by another. This edition is based on the Third Edition of 1857, revised by Gaskell and collated with the manuscript and the previous two editions, as well as with Charlotte Bronte`s letters, offering fuller information about the process of composition than any previous edition.
