| Abstract: | A wild strain of Stemphylium botryosum, when grown submerged in the presence of γ-terpinene (1), yielded the novel highly odour active terpene alcohol (2), whose structure was established by spectroscopic means as p-mentha-1,4-dien-9-ol. During cultivation (2) was further oxidized, predominantly to the corresponding aromatic alcohol p-cymene-9-ol (5). The enantioselective enzymatic introduction of the hydroxyl group at the non-activated C9 of (1) resulted in an enantiomeric excess (ee) of 74% for (2) and 70% for (5), respectively. |
