Enzymatic Regioselective Transformations in Natural Products,bonylations of polyhydroxylated compounds such as carbohydrates, nucleosides, and steroids are described. In many cases, chemoenzymatic routes are used to prepare analogs of natural products or intermediates. Oxime esters or carbonates are used as acylating or alkoxycarbonylating reagents in enzymat

This will be illustrated in the second part 2 of this chapter. During the past decades there has been an upsurge of interest in methods for the synthe

These empirical rules describe the shape and other features of either a good substrate (substrate model) or of the binding site (active sit

The biotransformation of nitrogen-containing groups is especially addressed. The bioreductions of trinitrotolu
