at benzylic or allylic centres. Competition from allylic hydroxylation of methyl groups was observed only when naphthalene dioxygenase was used as biocatalyst. The structures, enantiomeric excess values and absoluteconfigurations of the bioproducts, were determined by a combination of stereochemical correlation, spectroscopy (NMR and CD) and X-ray diffraction methods. cis-1,2-Diol metabolites from

Metabolism of bromobenzene and iodobenzene by growing cultures of Pseudomonasputida UV4 gave the corresponding cis-dihydrodiol products 1 and 2 in high yields; subsequent direct chemical substitution of the halogen atoms in these metabolites provided a new range of enantiomerically pure cis-dihydrodiols of known absolute configuration.

The whole-cell fermentation of aromatic coumpounds with Escherichia coli JM109 (pDTG601) on a medium scale (10-15 L) produces enantiopure cyclohexadienediols. A detailed procedure for the fermentation is described, and yields for several metabolites are provided. A similar procedure using E. coli JM109 (pDTG602) affords catechols. The dienediols are useful for asymmetric synthesis, and several important targets originating from these metabolites are tabulated.
