    A method to cleave C-C and C-0 bonds in β-Ο-4 linkages in lignin or lignin sub-units is described. The method includes oxidizing at least a portion of secondary benzylic alcohol groups in β-Ο-4 linkages in the lignin or lignin sub-unit to corresponding ketones and then leaving C-0 or C-C bonds in the oxidized lignin or lignin sub-unit by reacting it with an organic carboxylic acid, a salt of an organic carboxylic acids, and/or an ester of an organic carboxylic acids. The method may utilize a metal or metal-containing reagent or proceed without the metal or metal-containing reagent.
    描述了一种在木质素木质素亚单位中裂解β-Ο-4键中的C-C和C-0键的方法。该方法包括木质素木质素亚单位中β-Ο-4键中至少部分次基醇基团,使其转化为相应的,然后通过将化后的木质素木质素亚单位与有机羧酸、有机羧酸盐和/或有机羧酸反应,使C-0或C-C键保留在化后的木质素木质素亚单位中。该方法可以利用属或含属试剂,也可以在没有属或含属试剂的情况下进行。
  • Isolation of Functionalized Phenolic Monomers through Selective Oxidation and CO Bond Cleavage of the β‐O‐4 Linkages in Lignin

    Functionalized phenolic monomers have been generated and isolated from an organosolv lignin through a two‐step depolymerization process. Chemoselective catalytic oxidation of βO4 linkages promoted by the DDQ/tBuONO/O2 system was achieved in model compounds, including polymeric models and in real lignin. The oxidized βO4 linkages were then cleaved on reaction with zinc. Compared to many existing methods,

    The mechanisms for oxidative cleavage of several phenolic ethers, models for lignins, have been investigated by a detailed comparison of the result of anodic oxidation at nickel anodes in alkaline electrolyte with that of oxidation in acetonitrile in the presence of a triarylamine redox catalyst. The latter reaction is unambiguously initiated by single-electron transfer (SET), and in this case the major product of cleavage is aldehyde (vanillin or syringaldehyde derivatives). At nickel anodes polymerization is predominant although the aldehydes are formed together with larger amounts of the corresponding carboxylic acids. Combinations of 4-hydroxyl, alpha-keto, beta-O-aryl, and beta-hydroxymethyl functionality are shown to be crucial for the oxidation at nickel; the carboxylic acid formation probably involves a route with initial hydrogen atom abstraction at the surface. Important chemical conversions precede and accompany oxidation in alkaline media, and these are associated with the propensity for polymerization.
  • Cross-Coupling of Hydroxycinnamyl Aldehydes into Lignins
    作者:Hoon Kim、John Ralph、Nabila Yahiaoui、Michel Pean、Alain-M. Boudet

    [GRAPHICS]Pathways for hydroxycinnamyl aldehyde incorporation into lignins are revealed by examining transgenic plants deficient in cinnamyl alcohol dehydrogenase, the enzyme that converts hydroxycinnamyl aldehydes to the hydroxycinnamyl alcohol lignin monomers. In such plants the aldehydes incorporate into lignins via radical coupling reactions. As diagnostically revealed by long-range C-13-H-1 correlative NMR, sinapyl aldehyde (3,5-dimethoxy 4-hydroxy-cinnamaldehyde) 8-O-4-cross-couples with both gualacyl (3-methoxy-4-hydroxyphenyl-propanoid) and syringyl (3,5-dimethoxy-4-hydroxyphenyl-propanoid) units, whereas coniferyl aldehyde cross-couples only with syringyl units.
