NMR ASSIGNMENT FOR DIARYL ETHER STRUCTURES(4-O-5 STRUCTURES)IN PINE WOOD LIGNIN

摘要：

　　A4-O-5-tetramer lignin model compound carrying β-O-4 linkages on each of the side-chain moieties was synthesized,as well as 4–O–5-coupled dehydrodiconiferyl alcohol.By comparison with their NMR data,two cross-signals in the HSQC spectrum of pine milled wood lignin recorded in DMSO-d6 were assigned to H2/C2 and H6/C6 correlations on the aromatic rings of 4–O–5-linked units.Although the H2/C2 correlation peak appeared in the same region as syringyl units,nitrobenzene oxidation of the pine lignin did not yield any syringyl type product,but did release a 4–O–5-type product.
