The objective of this study was to investigate the effects of water tolerant Lewis acids (i.e., In(OTf)3, Yb(OTf)3 and InCl3) on bio-oil and solid residue yields. For this purpose, poplar wood was liquefied at 300 C with a residence time of 10 min without and with water tolerant Lewis acids in various concentrations from 0.5 to 10 wt% under hydrothermal conditions. The use of water tolerant Lewis acids had negative effects on bio-oil yields. The bio-oil from the run without a catalyst had a value of 17.50 wt% at 300 C, 10 min. The highest bio-oil yields under identical conditions were the following: 14.27 wt%, 13.37 wt% and 12.42 wt% for Yb(OTf)3 (with a concentration of 0.5 wt% of the raw material), In(OTf)3 and InCl3 (with concentrations of 1 wt% of the raw material). The concentrations of catalysts used in the experiments had significant effects on both bio-oil and solid residue yields. An increase of catalyst concentrations resulted in a decrease in bio-oil yields. The catalysts changed neither the molecular nor the elemental compositions of bio-oils and solid residues significantly. The prominent compounds in bio-oils from all runs including the run without a catalyst were phenol, 2,6-dimethoxyphenol, and 2-methoxyphenol.

Reference of 496-41-3, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.496-41-3, Name is Benzofuran-2-carboxylic acid, molecular formula is C9H6O3.

We describe the synthesis through visible-light photocatalysis of novel functionalized tetracyclic scaffolds that incorporate a fused azabicyclo[3.2.0]heptan-2-one motif, which are structurally interesting cores with potential in natural product synthesis and drug discovery. The synthetic approach involves an intramolecular [2 + 2] cycloaddition with concomitant dearomatization of the heterocycle via an energy transfer process promoted by an iridium-based photosensitizer, to build a complex molecular architecture with at least three stereogenic centers from relatively simple, achiral precursors. These fused azabicyclo[3.2.0]heptan-2-one-based tetracycles were obtained in high yield (generally >99%) and with excellent diastereoselectivity (>99:1). The late-stage derivatization of a bromine-substituted, tetracyclic indoline derivative with alkyl groups, employing a mild Negishi C-C bond forming protocol as a means of increasing structural diversity, provides additional modularity that will enable the delivery of valuable building blocks for medicinal chemistry. Density functional theory calculations were used to compute the T1-S0 free energy gap of the olefin-tethered precursors and also to predict their reactivities based on triplet state energy transfer and transition state energy feasibility.

We have developed a microwave-assisted catalytic Wittig reaction. In this paper, we give full account of the scope and limitations of this reaction. A screening of various commercially available phosphine oxides as precatalysts revealed Bu3P=O to be the most promising candidate. We tested 10 silanes for the in situ reduction of the phosphine oxide to generate Bu3P as the actual catalyst. Different epoxides were tested as masked bases. In this context, cyclohexene oxide as well as butylene oxide proved to be suitable. The reaction could be carried out at 125 C, but higher yields and E/Z selectivities were obtained at 150 C. Under the optimised reaction conditions, more than 40 examples for the conversion of various aldehydes into the corresponding alkenes are reported. The products were obtained in yields of up to 88 with high E selectivities. Moreover, we also describe the further screening of several chiral phosphines as catalysts for the microwave-assisted enantioselective catalytic Wittig reaction. The scope and limitations of the microwave-assisted catalytic Wittig reaction have been evaluated with respect to the catalyst, silane, solvent, reaction conditions, and substrates.

The extension of a previously reported cathepsin K azepanone-based inhibitor template to the design and synthesis of potent and selective inhibitors of the homologous cysteine protease cathepsin L is detailed. Structure-activity studies examining the effect of inhibitor selectivity as a function of the P3 and P2 binding elements of the potent cathepsin K inhibitor 1 revealed that incorporation of either a P3 quinoline-8-carboxamide or a naphthylene-1-carboxamide led to increased selectivity for cathepsin L over cathepsin K. Substitution of the P2 leucine of 1 with either a phenylalanine or a beta-naphthylalanine also resulted in an increased selectivity for cathepsin L over cathepsin K. Molecular modeling studies with the inhibitors docked within the active sites of both cathepsins L and K have rationalized the observed selectivities. Optimization of cathepsin L binding by the combination of the P3 naphthylene-1-carboxamide with the P2 beta-naphthylalanine provided 15, which is a potent, selective, and competitive inhibitor of human cathepsin L with a Ki = 0.43 nM.

Thermal behavior of different types of biomass, namely forestry – Eucalyptus globulus sawdust, Norway spruce (Picea abies) thermo mechanical pulp; agricultural – energy grass, Brassica rapa, and by-products – pine cones, grape seeds, was evaluated by thermogravimetry and by analytical pyrolysis. The liquid products from pyrolysis were analyzed by gas chromatography coupled with mass selective detector, Fourier transform infrared spectroscopy and by nuclear magnetic resonance spectroscopy. The elemental analysis and the calorific values of the pyrolysis residues were investigated. It has been established that the pyrolysis products consisted mainly of carboxylic acids, ketones, furans, phenols, guaiacols, catechols, and their derivatives, resulting from the degradation of the main structural components of biomass. The distribution of compounds in oils was strongly depended on biomass source, differences in the pyrolysis behavior among the biomass samples being found.
