Advances in Heterocyclic Chemistry

Although amorphous semiconductors have been studied for over four decades, many of their properties are not fully understood. This book discusses not only the most common spectroscopic techniques but also describes their advantages and disadvantages.Therapeutic Drug Monitoring: Newer Drugs and Biomarkers features timely topics such as the monitoring of classical and newer drugs, pharmacogenomics and the application of biomarkers in therapeutic drug monitoring. This reference also discusses the limitations of current commercially available immunoassays for therapeutic monitoring. It presents new and sophisticated techniques used for proper determination of blood levels and the clinical utility of therapeutic drug monitoring of contemporary drugs. Written by leading international experts and geared toward clinical pathologists, toxicologists, clinical chemists, laboratory professionals and physicians, this book is an essential resource on the current practice of therapeutic drug monitoring in improving patient safety.Advances in Heterocyclic Chemistry, Volume 103, deals with the organic chemistry of heterocyclic compounds, namely, photochromic dihetarylethenes, pyrido[1,2-a]azepines and their hydro derivatives, and 2-amino-4H-pyrans. Divided into three chapters, the book examines advances in the synthesis of these three compounds, including dithienylethenes that are derived from photochemically induced isomerizations between the cis- and trans-forms and cyclized derivatives. The book first looks at the synthesis of photochromic dihetarylethenes, such as perfluorocyclopentene-bridged dihetarylethenes, along with dithienylperhydrocyclopentenes and their heteroanalogs, like perhydrocyclopentenes, dithienylmaleic anhydrides, and dithienylmaleimides. It then discusses the McMurry reaction and the reactions between octafluorocyclopentene and lithium derivatives of thiophene. It also examines chemistry, structure, reactivity, and the pharmaceutical and agrochemical uses of of pyrido[1,2-a]azepines and their hydro derivatives. The book concludes with a summary of the synthesis, structure, reactivity, and practical significance of 2-amino-4H-pyrans. This book will benefit graduate students and research workers in academic and industrial laboratories who want to gain a better understanding of heterocyclic chemistry.
