✦ Synopsis

An Armillariella mellea culture was found to transform trans-sobrerol to a very small extent, whereas menthol resisted its action altogether. Acetylation of both alcohols, on the other hand, reappointed their reactivity in the same A . rnellea culture. Thus, trans-sobrerol -monoacetate and menthyl acetate underwent a two-step transformation involving hydroxylation (preserving the acetate link) to 3-acetoxy-6,8-p-methen-diol and 8-hydroxymenthyl acetate, respectively, which were converted by hydrolysis to 3,6,8-p-menthen-trioI and 8-hydroxymenthol, respectively.

The transformation of racemic menthyl acetate was enantiospecific; (-) 8-hydroxymenthol that was formed after 21 days contained 98% of enantiomer l R , 3R, 4s.
