Описание: Today, our world increasingly is conceived of as being molecular. An ever widening range of phenomena are described logically in terms of molecular properties and molecular interactions. The majority ofknown molecules are heterocyclic and heterocycles dominate the fields ofbiochemistry, medicinal chemistry, dyestuffs, photographic science and are of increasing importance in many others, including polymers, adhesives, and molecular engmeenng. Thus, the importance of heterocyclic chemistry continues to increase and this three volume work by Drs. R. R. Gupta, Mahendra Kumar and Vandana Gupta is a welcome addition to the available guides on the subject. Its scope places it in a useful niche between the single-volume texts and monographs ofheterocyclic chemistry and the multivolume treatises. The authors have retained the well tried classical approach but have succeeded in placing their own individual spin on their arrangement. They have put together a well selected range from among the most important ofthe vast array of facts available. This factual material is ordered in a clear and logical fashion over the three volumes. The present work should be of great value to students and practitioners ofheterocyclic chemistry at all levels from the advanced undergraduate upwards. It will be of particular assistance in presenting a clear and modem view of the subject to those who use heterocycles in a variety of other fields and we wish it well.
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.
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.

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: The author has summarized a decade of teaching combinatorial chemistry into this timely brief. The solid phase synthesis of unnatural heterocyclic alpha-amino acids is illustrated by practical examples starting from the ABCs of peptide synthesis explored in chapter one. Chapter two is concerned with the solid phase synthesis which is shown on various techniques – BillBoard, tea-bag, and Lantern devices, and demonstrated on heterocyclic examples and protocols. In the third chapter the tools for accelerating chemical synthesis – solid phase and liquid phase – are reviewed. Here the techniques of parallel refluxing (including microwave and flow technique) and parallel separation (filtration, centrifugation, evaporation, and chromatography) are described. In the chapters 4 and 5 the author goes on to describe how the liquid phase synthesis of heterocycles (reductive amination and Ugi reaction of heterocycles) is illustrated with the use of semi-automated protocols. Finally, the design of combinatorial libraries of heterocycles is reviewed including the original author’s findings.
