Biotransformations in Organic Chemistry

16The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale.This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts principles of stereoselective transformations, enzyme properties and kinetics the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and modified or artificial enzymes, are treated in a separate16 section. A final chapter deals with thebasic rules for the safe and practical handling of biocatalysts.In this completely revised 6th edition, emphasis has been given to an improved didactic style including coloured graphics in order to facilitate a deeper understanding of the underlying principles. New developments, such as transamination, enzyme promiscuity and applications on industrial scale within the field of 'white biotechnology' are included.04Introduction; Common Prejudices Against Enzymes; Advantages and Disadvantages of Biocatalysts; Enzyme Properties and Nomenclature.- Biocatalytic Applications: Hydrolytic Reactions; Reduction Reactions; Oxidation Reactions; Formation of Carbon-Carbon Bonds; Addition and Elimination Reactions; Glycosyl-Transfer Reactions; Halogenation and Dehalogenation Reactions.- Special Techniques: Enzymes in Organic Solvents; Immobilization; Modified and Artificial Enzymes.- State of the Art and Outlook.- Appendix: Basic Rules for Handling Biocatalysts; Abbreviations; Suppliers of Enzymes; Commonly Used Enzyme Preparations; Major Culture Collections; Pathogenic Bacteria and Fungi.
