Summary

3,4-Dimethoxycinnamyl alcohol (I) was actively metabolized by a white-rot fungus Coriolus versicolor in low nitrogen and high oxygen stationary cultures favouring the ligninolytic activity in the fungus. Substrate I was mainly oxidized to veratrylglycerol (III) which was a mixture of erythro and threo forms. Both isomers were degraded by cleavage between Cα and Cβ of the side chain to give veratraldehyde (VI), and (VI) was then reduced to veratryl alcohol (VII). A part of I was also metabolized via 1-(3,4-dimethoxyphenyl)-propane-3-ol (IV) and 1-(3,4-dimethoxyphenyl) propane-1,3-diol (VIII) by the fungus.
