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.

reductase-catalysed deoxygenations of sulfoxides, was found. The deoxygenations proceeded simultaneously, with the expected dioxygenase-catalysed asymmetric sulfoxidation of sulfides, during some biotransformations with the aerobic bacterium Pseudomonas putida UV4. Stereoselective reductase-catalysed asymmetric deoxygenation of racemic alkylaryl, dialkyl and phenolic sulfoxides was observed, without evidence

Oxidation of p-bromothioanisole with toluene dioxygenase provides the corresponding diene diol 2 in good yield. Electrochemical reduction of 2 gives access to diene diol 3, which is not accessible by direct bio-oxidation of thioanisole. Absolute configuration and enantiomeric purity are reported for the new metabolites. (C) 2004 Elsevier Ltd. All rights reserved.
