Two dilignols composed of ${\beta}$-O-4 structure, a important substructure compound in lignin, was synthesized in high yield in a series of the synthetic studies of lignin model compounds. The dimers were identified with $^1H$ and $^{13}C$-NMR and Mass spectroscopy. The important compound of among them, the final synthetic compound [IV].is called 1-(3,4-dimethoxyphenyl)-2-(2'-methoxy-4'-hydroxymethylphenoxy)-propanediol-l,3. This dimeric lignin model compounds should be usefull for the studies of lignin reactions such as pulping, bleaching, pyrolysis, hydrogenolysis, oxidation, reduction, biodegradation, and chemical utilization.
