A SPIRODIENONE COMPOUND WITH A β-1 LINKAGE FORMED BY OXIDATIVE CROSS COUPLING OF SINAPYL ALCOHOL γ-ACETATE WITH A SYRINGYL LIGNIN MODEL COMPOUND
A novel lignin model compound for the syringyl type of spirodienone structures (β-1/α-O-α) was obtained by oxidative coupling of sinapyl alcohol γ-acetate with 1-(4-hydroxy3,5-dimethoxyphenyl)ethanol. The 1H and 13C NMR chemical shifts for the acetate of the model compound were compared with the signals on HSQC NMR spectrum of acetylated avicenia lignin (MWL). The 1H and 13C chemical shifts of signals from α,β, and γpositions in one side chain part of the model were in well agreement with the corresponding correlation signals for spirodienone structures on the HSQC spectrum of the lignin.
