Presents the definitive serial in the field of heterocyclic chemistry Serves as the go-to reference for organic chemists, polymer chemists and many biological scientists Provides the latest comprehensive reviews as written by established authorities in the field Combines descriptive synthetic chemistry and mechanistic insight to enhance understanding of how chemistry drives the preparation and useful properties of heterocyclic compounds
Incorporation of Heterocycles into Combinatorial Chemistry

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.
Fluorine in Heterocyclic Chemistry Volume 1

This two-volume work combines comprehensive information on the chemistry of the fluorinated heterocycles. The material has been divided such that the first volume is dedicated to 5-membered fluorinated heterocycles and macrocycles, while the second volume combines data connected with the chemistry of fluorine containing 6-membered heterocycles. Both volumes will be of interest to synthetic organic chemists in general, and particularly for those colleagues working in the fields of heterocyclic-compound chemistry, materials chemistry, medicinal chemistry, and fluorine chemistry. All information is presented and classified clearly to be effective source for broad auditory of chemists. It will be interesting for scientists working in the field of inorganic and coordination chemistry. Fluorinated heterocycles are becoming increasingly important in many areas including the pharmaceutical industry, materials science and agriculture. The presence of fluorine can result in substantial functional changes in the biological as well as physicochemical properties of organic compounds. Incorporation of fluorine into drug molecules can greatly affect their physicochemical properties, such as bond strength, lipophilicity, bioavailability, conformation, electrostatic potential, dipole moment, pKa etc. as well as pharmacokinetic properties, such as tissue distribution, rate of metabolism and pharmacological properties, such as pharmacodynamics and toxicology.
