  • Visible‐Light‐Driven Cleavage of C−O Linkage for Lignin Valorization to Functionalized Aromatics

    renewable aromatics. Catalytic valorization of lignin into functionalized aromatics is attractive but challenging. Photocatalysis is a promising sustainable approach. The strategies for designing well-performing photocatalysts are desired but remain limited.

    木质素是可再生芳烃的最丰富来源。木质素到功能化芳族化合物的催化增值是有吸引力的,但具有挑战性。光催化是一种有前途的可持续方法。设计性能良好的光催化剂的策略是理想的,但仍然受到限制。在此,开发了在温和条件下促进锌-铟-硫化物(Znm In2 Sm + 3)的光催化裂解木质素β-O-4键的简便能带工程策略。Znm In2 Sm + 3的能带结构可以通过控制Zn / In的原子比来调节。发现Zn4In2S7在可见光照射下对于β-O-4键的裂解最有效,这是由于其合适的能带结构以提供足够的可见光吸收和合适的氧化还原能力。可以从有机溶剂桦木木质素中获得产率接近18.4重量%的官能化芳族单体。机理研究表明,β-O-4键主要通过Cα自由基中间体通过一步氧化还原中性途径被有效裂解。Zn4 In2 S7表面的硫醇基在β-O-4键断裂中起关键作用。

    CW electron paramagnetic resonance (EPR) investigation using the X-band, performed at the reaction temperature (298 K) showed that two phenoxy cobalt radicals ([CoIII(salen)(ROH)(RO˙)] and [CoIII(salen)(RO−)(RO˙)]) are involved in the oxidation mechanism of all the phenol compounds ROH. In a frozen solution the [CoIII(salen)(ROH))(RO˙)] radical prevailed and its axial magnetic anisotropy was determined

In the water-addition reaction, the threo isomers of the β-O-4 products were stereopreferentially formed more than the erythro isomers from both G- and H-type QMs (erythro/threo ratios of 24:76 and 50:50, respectively). The proportion of erythro isomers was higher at lower-pH conditions. This pH-dependent trend agrees with findings from a previous

  • DFRC Method for Lignin Analysis. 1. New Method for β-Aryl Ether Cleavage:  Lignin Model Studies
    作者:Fachuang Lu、John Ralph
    DOI:10.1021/jf970539p
    日期:1997.12.1
    A new method for selective and efficient cleavage of arylglycerol-beta-aryl (beta-O-4) ether linkages in lignins is described and applied to several Lignin beta-ether models. The term "DFRC" was coined for derivatization followed by reductive cleavage. Derivatization, accompanied by cell wall solubilization, is accomplished with acetyl bromide (AcBr); reductive cleavage of resulting beta-bromo ethers utilizes zinc in acetic acid. Degradation monomers, 4-acetoxycinnamyl acetates, from beta-ether cleavage by the DFRC method were identified by NMR, CC-MS, and comparison of GC retention times with authentic compounds. Under the conditions used in this study, the beta-ether linkage of all models was cleaved in very high (> 92%) yield. The DFRC method produces simpler mixtures of monomers with higher yields than alternative hydrolytic methods. Because of its relative simplicity, mild conditions, and exceptional selectivity, this method should become a powerful analytical method for lignin characterization.
  • GENES ENCODING CHAVICOL/EUGENOL SYNTHASE FROM THE CREOSOTE BUSH LARREA TRIDENTATA

    Particular aspects provide novel methods for redirecting carbon allocation in plants or cell culture from lignification to inherently more useful and tractable materials, and to facilitate the generation of, e.g., biofuels from the remaining plant roculture biomass. Particular aspects provided novel methods for converting monolignols into allyl/propenyl phenols, and for chavicol/eugenol formation or production. Additional aspects relate to the discovery of novel chavicol/eugenol synthases that convert p-coumaryl/coniferyl alcohol esters into chavicol/eugenol, and to novel compositions (e.g., novel proteins and nucleic acids encoding same), and novel methods using same for producing or forming chavicol/eugenol and other derivatives in cell culture and/or genetically modified plants, and for re-engineering the composition of plant biomass. Particular aspects provide novel methods for generation in culture or in planta of liquid/combustible allyl/propenyl phenols, and these phenolic products are utilized for (non-ethanol) biofuel/bioenergy purposes, while the remaining plant biomass facilitates the generation of other biofuels.
