Heterocyclic Chemistry covers the fundamentals of heterocyclic reactivity and synthesis for second- and third-year undergraduate chemistry students. It also includes more advanced material, making the book appropriate for postgraduate courses and researchers, either at postgraduate degree level or those working with heterocyclic compounds in industry. Essential teaching material is collected in specific introductory chapters, explaining heterocyclic reactivity principle in simple terms. These chapters are augmented by detailed, systematic discussions of the chemical reactivity of particular heterocyclic systems. References to both primary literature and reviews are given throughout the text.
