derivatives obtained by chemical reduction of III, and thus represent nitroreduction products. These derivatives have been identified as cis- and trans-oxime isomers of methyl 3,4-dichloro-2-furoate, based on spectroscopic analyses. These oximes were not mutagenic for TA100. Furthermore, III was more mutagenic under anaerobic conditions, suggesting that secondary superoxide or nitroanion free radicals
