Oxetane Synthesis rings play an important role as versatile motifs both in the overall formation of natural products and in synthetic organic chemistry. Oxetanes are important motifs in pharmaceutical chemistry that can confer improved metabolic and physicochemical properties. These developments continue to enhance the use of oxetanes in medicinal chemistry. Thanks to the growing commercial accessibility of oxetane possessing building blocks, together with improved approaches for the formation, oxetanes are likely to be progressively utilized in medicinal chemistry programs. Oxetanes are becoming valuable as a result of their vast diversity of uses in medicinal chemistry and varying applications. Several procedures have been developed for the formation and ring-opening of oxetanes to give important compounds in agrochemical, medicinal and material sciences. Novel approaches have been developed for the synthesis of oxetanes. These methods depend on both established synthetic approaches and development of many novel approaches for the formation of oxetanes. Highlights methods for the synthesis of oxetanes Includes new developments that enhance the use of oxetanes in medicinal chemistry Covers new approaches recently developed for the synthesis of oxetanes

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.

Heterocycles feature widely in natural products, agrochemicals, pharmaceuticals and dyes, and their synthesis is of great interest to synthetic chemists in both academia and industry. The contributions of recent applications of new methodologies in C–H activation, photoredox chemistry, cross-coupling strategies, borrowing hydrogen catalysis, multicomponent and solvent-free reactions, regio- and stereoselective syntheses, as well as other new, attractive approaches for the construction of heterocyclic scaffolds are of great interest. This Special Issue is dedicated to featuring the latest research that is ongoing in the field of heterocyclic synthesis. It is expected that most submissions will focus on five- and six-membered oxygen and nitrogen-containing heterocycles, but structures incorporating other rings/heteroatoms will also be considered. Original research (communications, full papers and reviews) that discusses innovative methodologies for assembling heterocycles with potential application in materials, catalysis and medicine are therefore welcome.

The number of available synthetic methods can be overwhelming. In order to create novel motifs and templates which confer new and potentially valuable drug-like properties, it is important to know which synthetic methodologies will give the best results. Similarly, which methodologies are used to progress potential drug candidates from leads through the development process? What are the current industrial research problems and how can they be resolved in an industrial setting? This book highlights key methods that have real impact in drug discovery and facilitate delivery of drug molecules. Synthetic Methods in Drug Discovery Volume 1 focuses on the hugely important area of transition metal mediated methods used in industry. Current methods of importance such as the Suzuki-Miyaura coupling, Buchwald-Hartwig couplings and CH activation are discussed. In addition, exciting emerging areas such as decarboxylative coupling, and the uses of iron and nickel in coupling reactions are also covered. This book provides both academic and industrial perspectives on some key reactions giving the reader an excellent overview of the techniques used in modern synthesis. Reaction types are conveniently framed in the context of their value to industry and the challenges and limitations of methodologies are discussed with relevant illustrative examples. Edited and authored by leading scientists from both academia and industry, this book will be a valuable reference for all chemists involved in drug discovery as well as postgraduate students in medicinal chemistry.

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 life possible. The Chemistry of Heterocycles 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

The guiding principle underlying the subject matter specifically compiled in Volume 5 has been to make available to the organic chemical community a sourcebook comprehensively covering all the important &pgr;-bond-dependent transformations. Thermal, photochemical, and metal-catalyzed cycloadditions of every major type are expertly detailed by the most knowledgeable researchers in these areas. The synthetically useful electrocyclic and sigmatropic processes where alkenic centers are intimately involved in the structural change are similarly canvassed in compact detail. With added attention given to ene reactions, small-ring rearrangements, and related transition metal-associated reactions, coverage has been achieved of the full range of organic transformations directly involving the rebonding of alkenic centers. As a consequence, this volume should serve as the comprehensive sourcebook of the field for the next decade and beyond.
