The biotransformation of the diastereoisomers. (-)-cis-myrtanol and (+)-trans-myrtanol, by Glomerella cingulata has been investigated. (-)-cis-Myrtanol was initially converted to (3S)-3-hydroxy-cis-myrtanal, (4R)4-hydroxy-cis-myrtanol, 5-hydroxy-cis-myrtanol and [1R, 4R, 5S]-thujane-7, 10-diol having the cyclopropane ring. (4R)-4-Hydroxy-cis-myrtanol was further converted to 4-oxo-cis-myrtanol. By comparison (+)-trans-myrtanol was converted to 3-oxo-trans-myrtanol, 9-hydroxy-trans-myrtanol, 4-oxo-trans-myrtanic acid and 5-hydroxy-trans-myrtanic acid. The structures of the metabolic products were determined by spectral methods.
