Synthesis of Epoxides explores different ways of making epoxides, both old and new, and delves into the growing field of heterocyclic chemistry. It's aimed at people who want a variety of methods and need help figuring out which one suits their specific needs. For students, having all the protocols for making epoxides in one place is handy because sometimes you just want to see all the options for creating a particular compound from a specific starting point. Diazo compounds are important synthetic intermediates in organic synthesis but, because of their unpredictable explosive nature and toxicity, their unique reactivity has not been fully exploited and their employment on large scale is avoided. The synthetic usefulness of diazo compounds cannot be overlooked despite their danger. Because of their ylide and 1,3-dipole nature, the diazo compounds have a unique reactivity. The diazo compounds can be utilized for various different conversions including S-ylide-assisted epoxidation, cyclopropanation, or aziridination reactions. This book describes the new and classic methods for the synthesis of epoxides and covers an important and rapidly growing branch of heterocyclic chemistry. Readers will learn about different methods and want information allowing them to evaluate which method is most suitable in particular cases. Students will be able to find the protocols for the synthesis of epoxides in one place within this book because sometimes we want to see all of the possibilities for synthesizing a particular compound from one particular substrate.

Synthesis of Six- and Seven-Membered Heterocycles: The Role of DMF and its Synthesis compares different synthetic approaches using DMF, including the advantages and disadvantages of those reactions, green methods, and the sustainability of reported synthetic methodologies, especially the microwave methods. The book presents several methodologies for the synthesis of six- and seven-membered heterocyclic compounds using dimethylformamide. Users will find the most up-to-date information in this fast-moving field which can be particularly challenging. With DMF drawing the attention of synthetic organic chemists, this book will help readers understand further developments in the uses of dimethylformamide beyond just its use as a polar solvent. As it can be expected that the use of dimethylformamide as a precursor will continue to grow in organic synthesis with new applications in sustainable and green chemistry, this book provides an ideal primer on the topics covered.

Four-Membered Heterocycle Synthesis offers a comprehensive approach to these unstable organic compounds, providing a systematic introduction to the synthesis and reactions of all common four-membered heterocycles and illustrating different methods to prepare specific four-membered heterocycles. Four-membered heterocyclic compounds are known as a class of unstable organic compounds because of their strain characteristics, which make them very beneficial as precursors for the formation of a broad range of complex heterocyclic molecules and for synthetic elaboration.

The book will be greatly helpful for everyone involved inthe field and can pave the way for better understanding and quantification of heterocycle synthesis.

Synthesis of Azetidines from Imines by Cycloaddition Reactions presents several methodologies for the synthesis of azetidines from imines by cycloaddition reactions.  The azetidines, known as important contribution of science to humanity, are important organic compounds that have occupied a basic position in the pharmaceutical chemistry for over a hundred years because of their biological activities. They are the fundamental skeleton of several antibiotics, probiotics and alkaloids. The synthesis of azetidines is a constant challenge for medicinal chemists, hence this book comprehensively describes azetidine ring synthesis. With this book, readers will be able to quickly assess possible synthetic approaches and evaluate whether preparation of a four-membered nitrogen containing ring is reasonable.

Heterocyclic frameworks represent the main structural subunits of many biologically active compounds and natural products. The ability of heterocycles to act both as reactive pharmacophores and biomimetics has greatly contributed to their unique value as traditional key elements of various drugs. The contemporary developments in process chemistry and discovery emphasize novel sustainable synthetic pathways as fast and ecologically acceptable alternatives to the traditional protocols. The development of sustainable synthetic process to substitute the efficient but somewhat old classical methodologies started many years back and such methodologies are still in high demand.  The increasing demand for fast formation of biologically active molecules has stimulated synthetic researchers to discover and develop smart approaches that inevitably address the very fundamental principles of effectiveness and efficiency. Besides the critical issues of stereo-, chemo-, and regioselectivity, nowadays, these processes also have to account economical and environment concerns of green chemistry. The intellectual difficulty to discover well-designed, concise, and conceptually new synthetic pathways has become a gradually increasing driving force in industry and academia. Since the last few years, chemists are very concerned about the environmental implications of their work. They are trying to develop novel reaction conditions, synthetic strategies, and use of chemicals that minimize risks to environment and humans. The development of harmless, atom efficient, and acid-mediated organic procedures is the most important challenge in green chemistry. While acid catalysis remains the most broadly utilized kind of catalysis, the generally employed acid catalysts continue to pose severe safety and health issues. The mild Lewis acidity of I2 has increased its applicability for many organic reactions.
