Synthesis of Epoxides explores different techniques for making epoxides, both old and new, and delves into the growing field of heterocyclic chemistry. The book presents a variety of methods that will help readers figure out which one best suits their specific needs. 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 use at large scale has been avoided. Readers, including students in chemistry, will learn about different methods and important information, allowing them to evaluate which method is most suitable in particular cases. 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.
