Isolation and characterization of rat intestinal bacteria involved in biotransformation of (-)-epigallocatechin.
Arch. Microbiol. 196(10) , 681-95, (2014) Two intestinal bacterial strains MT4s-5 and MT42 involved in the degradation of (-)-epigallocatechin (EGC) were isolated from rat feces. Strain MT4s-5 was tentatively identified as Adlercreutzia equolifaciens. This strain converted EGC into not only 1-(3, 4, ... |

Nonenzymatic sugar production from biomass using biomass-derived γ-valerolactone.
Science 343(6168) , 277-80, (2014) Widespread production of biomass-derived fuels and chemicals will require cost-effective processes for breaking down cellulose and hemicellulose into their constituent sugars. Here, we report laboratory-scale production of soluble carbohydrates from corn stov... |

Conversion of biomass-derived levulinate and formate esters into γ-valerolactone over supported gold catalysts.
ChemSusChem 4(12) , 1838-43, (2011) The utilization of biomass has recently attracted tremendous attention as a potential alternative to petroleum for the production of liquid fuels and chemicals. We report an efficient alcohol-mediated reactive extraction strategy by which a hydrophobic mixtur... |

Palladium-catalyzed decarboxylative [4 + 3] cyclization of gamma-methylidene-delta-valerolactones with 1,1-dicyanocyclopropanes.
Org. Lett. 11(24) , 5642-5, (2009) A palladium-catalyzed decarboxylative [4 + 3] cyclization of gamma-methylidene-delta-valerolactones with 1,1-dicyanocyclopropanes has been developed to produce cycloheptane derivatives in a convergent manner. This method can be applied to the synthesis of aze... |

Production of aromatic hydrocarbons through catalytic pyrolysis of γ-valerolactone from biomass.
Bioresour. Technol. 114 , 740-4, (2012) In the present study, γ-valerolactone (GVL) is firstly reported to be converted into aromatic hydrocarbons through catalytic pyrolysis. The catalysts and reaction conditions are both critical in maximizing the hydrocarbon selectivity. Four zeolites, i.e. MCM-... |

Selective homogeneous hydrogenation of biogenic carboxylic acids with [Ru(TriPhos)H]+: a mechanistic study.
J. Am. Chem. Soc. 133(36) , 14349-58, (2011) Selective hydrogenation of biogenic carboxylic acids is an important transformation for biorefinery concepts based on platform chemicals. We herein report a mechanistic study on the homogeneously ruthenium/phosphine catalyzed transformations of levulinic acid... |

Maximising opportunities in supercritical chemistry: the continuous conversion of levulinic acid to gamma-valerolactone in CO(2).
Chem. Commun. (Camb.) (44) , 4632-4, (2007) Phase behaviour is manipulated during the hydrogenation of aqueous levulinic acid in supercritical CO(2) to separate almost pure gamma-valerolactone from water and unreacted acid with reduced energy requirements compared to conventional processing. |
