Outline of Final Research Achievements

13C Labeled lignin dimeric model compound, a guaiacyl unit linked to a syringyl one by β-O-4 bond, was synthesized, and treated by laccase/1-hydroxybenzotriazole. Following the process of laccase- generated reaction by 13C-NMR, an oxidation at benzylic position and a cleavage of Cα-Cβ bond of lignin dimeric model compound were observed. Veratric acid was determined as a reaction product, although it was not found in the laccase-generated reaction solution of the oxidized dimeric model compound product as a substrate.
