Abstract
The application of biologically derived catalysts to the synthesis of agrochemicals has become increasingly popular in recent years. In most cases, the aim of using a biotransformation is either to introduce chirality into the molecule, to achieve a regioselective functionalization, or to selectively convert a functional group among other groups with similar reactivity. Pheromones, which have recently been commercialized as agrochemicals, are generally used in enantiopure forms with their intentional mixtures. Since they are usually highly effective, only very small quantities are needed to achieve the desired activity. This review, with approximately 200 references covering the period previous to December 2004, describes various efficient means of preparing optically pure pheromones and their precursors with the aid of isolated enzymes and microorganisms serving as catalysts.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
