Abstract: | The following processes are discussed in this article: enzyme-catalysed hydrolyses of carboxylic acid esters and amides, phosphate esters, nitriles and epoxides; esterification and inter-esterification reactions catalysed by enzymes; reduction of ketones to secondary alcohols using whole-cell systems or isolated dehydrogenases; oxidation of alicyclic and aromatic substrates using mono-oxygenases and dioxygenases in bacteria and fungi including enzyme-catalysed Baeyer-Villiger oxidations; aldol reactions, formation of optically active cyanohydrins and enzyme-catalysed acyloin type reactions. The use of these biocatalytic methods for the stereo-controlled preparation of important target structures is reviewed and some of the future directions for the biotransformation area are discussed. |
