before the fermentation was found to have a major effect on the course of the biohydroxylation relative to the achiral analogue 3a (Table 1, entry 1). The nature of R1/R2 influenced both the product yield and the optical purity of the products (e.g. Table 1, entry 2). In addition, the absolute configuration of the final product 6 could be dictated solely by the nature of the docking/protecting group
