Heterocyclic compounds constitute the largest group of Organic Chemistry because of their chemical, biological and technical significance. The book entitled "The Essence of Heterocyclic Chemistry" offers an overview of approximately 150 heterocycles in single volume. The Chemistry of each molecule is discussed under sub-heads which allow the students to quickly understand the concept of heterocyclic chemistry. It comprises synthesis of individual ring system along with physical and spectral properties, the chemical behaviour and important application if any, in a lucid and simple language.The discussion is restricted to parent compound and simple derivative by citing suitable examples so that fundamentals of heterocyclic chemistry can be understood thoroughly by a student. The content of the book is carefully designed with special emphasis on heteroaromatic compounds to cater the needs of graduate, post-graduate and research students of National and International universities. Considerable data is provided for some ring systems having significance in heterocyclic chemistry in detailed manner. This makes the book appropriate as a reference text for researchers in Pharmaceutical Chemistry and other related fields.
Experts’ Views About the Book:

Dr. K R Desai.Former Professor and Head, Chemistry Department, South Gujarat University, Surat. Because of the rich diversity of physical and biological properties heterocycles continue to be of immense interest to both the academicians and industrial chemists. This book is one of the best introductory textbook on heterocyclic chemistry. This is a valuable book for all, which begins with a detailed chapter on nomenclature of heterocyclic compounds cited with several examples. The authors have presented chemistry of each particular class of heterocycles covering synthesis and chemical reactivity. They have made good choice among the several heterocycles and synthesis options to limit the complexity of the book. The book is clearly written, logically organized to offer students at graduate and specially at post-graduate level. For researchers it is a valuable resource of information on important aspects of heterocyclic chemistry.

Dr. B K Mehta.Professor and Head, Chemistry Department, Vikram University, Ujjain.Heterocycles are of vital importance in the race to improve our understanding of the basic chemistry which underlies all important life processes. The authors have provided unique collection of information on important aspects of approximately 150 heterocycles ranging from three to nine membered ring system. The book comprises synthesis of individual ring system along with spectral and chemical properties to allow the students to quickly understand the concepts of heterocyclic chemistry. This book is well written, concise and meets the needs of graduate and post-graduate students along with researchers.

Dr. John Parrick.Professor and Head, Chemistry Department, Brunnel University, London.This book aims to provide postgraduate students with a basic understanding of heterocyclic chemistry. It starts with a useful chapter on nomenclature including partially reduced heterocycles and polycyclic structures containing a heterocyclic nucleus. Subsequently, the heterocycles containing N, O and S are addressed in order to increase ring size along with consideration to the natural occurrence, synthesis, physical properties and chemical reactivity of important derivatives of each heterocycle. Heterocycles containing phosphorus and selenium atoms are also mentioned. Reaction mechanisms are not given in the reaction schemes but sometimes hints to the mechanisms are given in the text. The book discusses the range of heterocycles from three to nine membered rings including those containing two or more heteroatoms. In addition, fused ring systems are also discussed. The book is a useful reference work.
