The Chemistry of Heterocycles Volume 1 covers an introduction to the topic, followed by a chapter on the nomenclature of all classes of isolated, fused and polycyclic heterocycles. The third chapter delineates the highly strained three membered N,O and S containing aromatic and non-aromatic heterocycles with one and more than one similar and dissimilar heteroatom. The four-membered heterocycles are abundantly present in various natural and synthetic products of pharmacological importance. This chapter describes the natural abundance, synthesis, chemical reactivity, structural features and their medicinal importance. This class of compounds are present as sub-structures in penicillin and cytotoxic Taxol. Lastly, a chapter on the natural abundance, synthesis, chemical reactivity and pharmacological importance of 5-membered heterocycles with N,O,S heteroatom is covered. The chemistry of heterocycles with mixed heteroatom such as, N-S, N-O, N-S etc. is also described. Gives in-depth, clear information about various systems of nomenclature along with widely acceptable IUPAC system for naming various classes of heterocycles Provides complete information about natural occurrences, synthesis, chemical reactivity, pharmacological importance of heterocycles and their application in material science Highly relevant for graduate students and researchers, providing updated information about various isolated and fused N,O and,S containing heterocycles ER -
