for biocatalysis in the broader community and to give an overview of the field. As all SoS volumes, "Biocatalysis in Organic Synthesis" offers critical reviews of organic transformations by experts, including experimental procedures. The organization is based on the type of reaction performed under biocatalysis. Volume 3 begins by describing oxidation. A chapter on dihydroxylation is followed by reviews of alkane oxidation. Oxidations of alcohols, carbonyl compounds, and heteroatoms are also covered, as are halogenations. The use of biocatalysts in total synthesis, cascade reactions, and the development of large-scale processes are considered. Finally, emerging trends are outlined.
