Advances in Detailed Reaction Mechanisms, Volume 4: Synthetically Useful Reactions focuses on synthetically useful reactions, including transition-metal-mediated cycloadditions, the use of organoselenium, organozinc, and metal-arene complexes. This book discusses flavonoid synthesis by cyclization of hydrochalcone. Organized into six chapters, this volume begins with an overview of the mechanistic issues related to a number of metal-mediated cycloaddition reactions that are significant in the context of organic synthesis. This text then examines the basic reaction types that generate carbon–carbon bonds. Other chapters consider enzyme and metal-ion-catalyzed isomerization of sugars. This book discusses as well the reaction patterns inherent in polyfunctional organic molecules that are associated with functional groups. The final chapter deals with the nonenzymatic and enzyme-catalyzed-scale industrial production triggered by commercial applications. This book is a valuable resource for organic synthesis chemists. Scientists and research workers who are interested in synthetically useful reactions will also find this book extremely useful.
