Metabolism of camphanediols

1. The metabolism of the camphane-2,3-diols and camphane was investigated in rabbits. All the compounds increased the content of glucuronide in the urine. 2. Both trans- and cis-diols gave rise to ketols; the cis-diols gave rise to trans-diols, but not vice versa; camphorquinone gave cis-diol, ketols and trans-diol; camphane did not give rise to diols. 3. The possibility is discussed that an enediol is the intermediate for ketol interconversions in the present series of compounds and in other series such as hydroxyoestrones and hydroxyindanones.
