M. Atta-ur-rahman,"yaqoob et al., Fungal transformation of (1R,2S,5R)-(-)-menthol by Cephalosporium aphidicola, J NAT PROD, 61(11), 1998, pp. 1340-1342
Incubation of (1R,2S,5R)-(-)-menthol (1) with Cephalosporium aphidicola for
12 days yielded the six oxidized metabolites: 10-acetoxymenthol (2), 7-hyd
roxymenthol (3), 4 alpha-hydroxymenthol (4), 3 alpha-hydroxymenthol (5), 9-
hydroxymenthol (6), and 10-hydroxymenthol (7). The structures of the novel
compounds 2, 4, 5, and 7 were assigned by interpretation of their spectral
data.
