Advances in Triazole Chemistry reviews the ever-widening scope of triazole chemistry. Triazole is an exceptional structural motif with a range of applications across scientific disciplines, including materials science, organocatalysis, agrochemicals, and medicinal chemistry. These many applications of different classes of triazoles have promoted the development of a range of synthetic strategies over the past few years, which are presented here along with recent and ecofriendly methods for the synthesis of all types of triazoles. The book also reviews the recent notable applications in chemical ligation, peptidomimetics, carbohydrate chemistry, nanotechnology, and polymer and materials science. This comprehensive resource is ideal for researchers using triazoles in various disciplines, as well as chemists working in the pharmaceutical, polymer, and agrochemical industries. Includes coverage of the role triazoles play in DNA synthesis Features comprehensive information on 1,2,3-triazoles and 1,2,4-triazoles and their subclasses, synthesis, and applications Serves as an ideal reference for researchers and chemists interested in using triazole chemistry for functionalization, modification, and development of target products

Nuclear Magnetic Resonance (NMR) spectroscopy is a nondestructive technique that can be used to characterize a wide variety of systems. Sustained development of both methodology and instrumentation have allowed NMR to evolve as a powerful technology, with applications in pure sciences, medicine, drug development, and important branches of industry. NMR provides precise structural information down to each atom and bond in a molecule, and is the only method for the determination of structures of molecules in a solution. This book compiles a series of articles describing the application of NMR in a variety of interesting scientific challenges. The articles illustrate the versatility and flexibility of NMR.

Progress in Heterocyclic Chemistry (PHC) is an annual review series commissioned by the International Society of Heterocyclic Chemistry (ISHC). Volumes in the series contain both highlights of the previous year’s literature on heterocyclic chemistry and articles on emerging topics of particular interest to heterocyclic chemists. The chapters in Volume 21 constitute a systematic survey of the important original material reported in the literature of heterocyclic chemistry in 2008. Additional articles in this volume review "Biocatalytic approaches to chiral heterocycles" and "Ring-expanded (‘fat’) purines and their nucleoside/nucleotide analogues as broad-spectrum therapeutics." As with previous volumes in the series, Volume 21 apprises academic/industrial chemists and advanced students of developments in heterocyclic chemistry in a convenient format. * Covers the heterocyclic literature published in 2008 * Includes specialized reviews * Features contributions from leading researchers in their fields
