We report novel polar metabolites of (−)3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan prepared by a novel process of microbial fermentation using a fungi, Fusarium lini , of unique structures that would be difficult to predict opening up the possibilities of their chemical synthesis. The polar metabolites discovered have stronger aromatic characteristics and offer a new highly prized odiferous characteristic quite different from that of the parent compound and thus can be used in the preparation of perfumes, odor-masking and other odor-management applications.
