Reaction of coniferyl alcohol or sinapyl alcohol with 尾-O-4 dimeric model compounds in the presence of manganese(III), copper(II), or vanadium(V) gave trimeric compounds that served as superior models for13C chemical shift assignments in natural and synthetic lignins. By appropriate choice of ...
The 13C NMR spectrum of a biomimetic guaiacyl-DHP (G-DHP) from coniferyl alcohol was very similar to that of a lignin isolated from spruce wood, unlike a corresponding spectrum of a G-DHP prepared by a conventional enzymic technique. A similar comparison between a biomimetic guaiacyl/syringyl ...
Dehydropolymerization of p-hydroxycinnamyl alcohols with metal salt oxidants resulted in several novel DHPs. A DHP prepared by treatment of coniferyl alcohol with Mn+3 was found to more closely approximate the structure of pine milled wood lignin than DHPs produced by enzymic techniques. The C...
DHPs were formed from p-coumaryl and coniferyl alcohols with the crude peroxidase preparation and from sinapyl alcohol when this was mixed with p-coumaryl and coniferyl alcohols. Characteristics properties of DHPs were similar to those of lignins isolated from healthy and diseased roots. DHP ...
By use of a lithium aluminum hydride reduction coniferyl alcohol can be obtained directly from Siam Benzoin gum, whereas attempted saponification only results in polymerization of the benzoate ester.doi:10.1016/S0031-9422(00)88205-9Herbert A. Schroeder...

The C-13 NMR spectrum of a biomimetic guaiacyl-DHP (G-DHP) from coniferyl alcohol was very similar to that of a lignin isolated from spruce wood, unlike a corresponding spectrum of a G-DHP prepared by a conventional enzymic technique. A similar comparison between a biomimetic guaiacyl/syringyl...
