start a new wave of enthusiasm for biocatalysis in the broader community and to give an overview of the field. As is the case with all of the Science of Synthesis volumes, "Biocatalysis in Organic Synthesis" offers critical reviews of organic transformations by experts, including typical or general experimental procedures. The content organization of the three volumes is based on the type of reaction performed under biocatalysis. Volume 2 covers reactions involving the formation of C-C bonds. Addition of carbon nucleophiles at C-O and C-N double bonds are reviewed, as are methods for the formation of C-C bonds at arenes and additions to C-C double bonds. Other chapters present transamination and reductive amination reactions, reduction of carbonyl compounds, and the chemistry of epoxides
