Functionalized phenolic monomers have been generated and isolated from an organosolv lignin through a two-step depolymerization process. Chemoselective catalytic oxidation of β-O-4 linkages promoted by the DDQ/tBuONO/ O2 system was achieved in model compounds, including polymeric models and in real lignin. The oxidized β-O-4 linkages were then cleaved on reaction with zinc. Compared to many existing methods, this protocol, which can be achieved in one pot, is highly selective, giving rise to a simple mixture of products that can be readily purified to give pure compounds. The functionality present in these products makes them potentially valuable building blocks.

Lignin model compounds of the arylglycerol β-syringyl ether type have been prepared by the reaction of aromatic aldehydes with the α-lithiated carboxylate of (2,6-dimethoxyphenoxy)acetic acid and subsequent reduction of the 3-aryl-2-(2,6-dimethoxyphenoxy)-3-hydroxypropanoic acids formed.
Stereochemical Assignment of the threo and erythro Forms of 2-(2,6-Dimethoxyphenoxy)-1-(3,4-dimethoxyphenyl)-1,3-propanediol from X-Ray Analyses of the Synthetic Intermediates (Z)-2-(2,6-dimethoxyphenoxy)-3-(3,4-dimethoxyphenyl)-2-propenoic Acid and threo

The crystal structures of (Z)-2-(2,6-dimethoxyphenoxy)-3-(3,4-dimethoxyphenyl)-2-propenoic acid (7) and threo-2-(2,6-dimethoxyphenoxy)-3-(dimethoxyphenyl)-3-hydroxypropanoic acid (10) were determined from single-crystal X-ray diffractometer data.Starting
