A. Farooq et Jr. Hanson, THE BIOTRANSFORMATION OF 4-TERT-AMYLCYCLOHEXANONE AND 4-TERT-BUTYLCYCLOHEXANONE BY CEPHALOSPORIUM-APHIDICOLA, Journal of chemical research. Synopses, (2), 1996, pp. 104-105
4-tert-Amyl and 4-tert-butylcyclohexanone are shown to be hydroxylated
on the 4-substituent by Cephalosporium aphidicola. The carbonyl group
is also reduced and the alcohols are also hydroxylated.
