Non-enzymic and enzymic oxygenation reactions of (±)-dibenzocyclooctadiene lignan, (±)-deoxyschizandrin (1) using a simple model system for mono-oxygenases Fe(MeCN)62+-Ac2O-H2O2 and rat liver S9 mix were investigated in connection with mammalian and plant metabolisms of the corresponding lignans. The non-enzymic reaction of 1 gave the two phenol acetates 4a and 5a and a quinone 6, and the enzymic reaction of 1 afforded several compounds for which three compounds characterized as 7, 8 and 9 were isolated. The latter results has implications for biosynthesis of these lignans.
