New cis-diol metabolites of both aromatic and non-aromatic heterocyclic rings have been isolated from growing cultures of a mutant strain of the soil bacterium Pseudomonas putida(UV4) and stereochemically assigned; a novel heterocyclic cis-diol of benzothiophene, 2,3-dihydroxy-2,3-dihydrobenzothiophene is found to exist exclusively in the cis-configuration in water but equilibrates readily with the trans-isomer.
