The importance of enantioselective synthesis in modern organic chemistry means that there is a continuing need for the development of new asymmetric methodologies. 1., , and Among the numerous methods for asymmetric synthesis, efficient enzyme- or microorganism-catalysed transformation is a preferred tool 2., , , 3., 4., 5. and 6. with respect to the chemo-, regio- and enantioselectivity of such transformations and additional environmental aspects. This is particularly true in ...
