This book, Chiral Thioethers: Synthesis and Applications, provides a comprehensive exploration of chiral thioethers, covering their chemistry, synthesis, transformations, and diverse applications. It details both modern catalytic approaches (e.g., organocatalysis, photocatalysis, biocatalysis) and advanced traditional methods (e.g., nucleophilic substitution, coupling reactions) for chiral thioether synthesis, along with their limitations and improvements. Additionally, it explores transformations of chiral thioethers and their critical roles in medicine (drug development), asymmetric catalysis (as ligands), and agrochemicals (pesticides, fungicides). Written for academics and scientists, this book bridges basic concepts and cutting-edge research, making it a valuable resource for understanding the synthesis strategies and practical applications of chiral thioethers.
