cis-Dihydrodiols of anthracene and benz[a]anthracene, and acetonide derivatives of the cis-dihydrodiols of benzene, fluorobenzene, biphenyl and phenanthrene have been identified as substrates for dioxygenase enzymes, yielding the corresponding enantiopure arene bioproducts, bis(cis-dihydrodiol)s and cis-diol acetonides respectively.

dioxygenase-catalysed cis-dihydroxylation of monosubstitutedbenzene substrates, have been used as synthetic precursors of the corresponding trans-3,4-dihydrodiols. The six-step chemoenzymatic route from cis-dihydrodiol precursors, involving acetonide, tetraol, dibromodiacetate and diepoxide intermediates, and substitution of vinyl bromide and iodide atoms, has been used in the synthesis of ten trans-dihydrododiol derivatives
