(+)- and (-)-Camphorquinones were readily reduced by various fungi. Th
e reduction of (-)-camphorquinone by Aspergillus niger produced mainly
(+)-2R-endo-hydroxyepicamphor with high stereoselectivity whereas red
uction of (+)-camphorquinone by Glomerella cingulata and Mucor mucedo
afforded (-)-3S-exo-hydroxycamphor with stereoselectivity.
