An efficient Rh(III)-catalyzed stepwise ortho allylation of N-methoxybenzamides 1 with polysubstituted allenes is reported. This C-H functionalization involving allenes is conducted under very mild conditions (-20 C or room temperature) and compatible with ambient air and moisture, and it can be applied to terminal or internal allenes with different synthetically attractive functional groups. Highly efficient axial chirality transfer has been realized, yielding optically active lactones.

Application of 16859-59-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one, molecular formula is C8H6O3. In a Article，once mentioned of 16859-59-9

Ring chain tautomerism with slow interconversion (compared with the NMR timescale) was observed in solutions of 2-(2,2-dicyano-1-methylethenyl)benzoic acid (3e), obtained by Knoevenagel condensation of 2-acetylbenzoic acid with malononitrile, forming the ring tautomer 3-dicyanomethyl-3-methylphthalide (4e) in admixture with 3e. Similar condensations of 2-formylbenzoic acid with methyl cyanoacetate or malononitrile give 2-(2-cyano-2-methoxycarbonyl-ethenyl)benzoic acid (3b) and 2-(2,2-dicyanoethenyl)benzoic acid (3d), respectively, which in solution also exhibit the same tautomerism to give the ring tautomers, 3-(cyanomethoxycarbonylmethyl)phthalide (4b) and 3-(dicyanomethyl)phthalide (4d), respectively. Condensation of 2-formylbenzoic acid with dimethyl malonate gave only the ring compound, 3-(dimethoxycarbonylmethyl)-phthalide (4a). Attempts to synthezise 2-(2-cyano-2-methoxycarbonyl-1-methylethenyl)benzoic acid (3c) by methylation of the trimethyl silylester of 3b with diazomethane led to the ring form of 3c, viz. 3-cyanomethoxycarbonylmethyl-3-methylphthalide (4c) as an equimolar mixture of two diastereomers. No tautomerism was observed when the benzene ring was replaced by a thiophene ring (7a, 7b and 8) or an aliphatic double bond (9). Solid state spectra (IR and NMR) indicated that all compounds carrying two cyano groups at the double bond, except the aliphatic compound 9, were in the open-chain form, while all the others were in the ring form. Equilibrium studies for compound (3e?4e) indicated increased stability for the chain form 4e with increasing solvent polarity. Determination of the free energy change, DeltaG, and of the free energy of activation, DeltaG?, for the tautomerization in deuteriochloroform (using 1H NMR spectroscopy) indicated that, in this solvent, a concerted process from the starting material 3e to the anion of 4e is taking place. It is also postulated that a similar reaction path is followed in the other solvents used in this investigation, all belonging to the solvent class ‘protophobic dipolar aprotic solvents’.

Application of 4265-25-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other?

The BTL (biomass-to-liquid) process is an attractive process that produces liquid biofuels from biomass. The FT (Fisher-Tropsch) process is used to produce synfuels such as diesel and gasoline from gasified biomass. However, the H2S (hydrogen sulfide), COS (carbonyl sulfide) and CO2 (carbon dioxide) in the syngas that are produced from the biomass gasifiers cause a decrease of the conversion efficiency and deactivates the catalyst that is used in the FT process. To remove the acid gases, a pilot-scale methanol absorption tower producing diesel at a rate of 1BPD (barrel per day) was developed, and the removal characteristics of the acid gases were determined. A total operation time of 500h was achieved after several campaigns. The average syngas flow rate at the inlet of methanol absorption tower ranged from 300 to 800L/min. The methanol absorption tower efficiently removed H2S from 30ppmV to less than 1ppmV and COS from 2ppmV to less than 1ppmV with a removal of CO2 from 20% to 5%. The outlet gas composition adhered to the guidelines for FT reactors. No remaining sulfurous components were found, and the tar component was analyzed in the spent methanol after long-term operations.

A novel series of shikonin-benzo[b]furan derivatives were designed and synthesized as tubulin polymerization inhibitors, and their biological activities were evaluated. Most compounds revealed the comparable anti-proliferation activities against the cancer cell lines to that of shikonin and simultaneously low cytotoxicity to non-cancer cells. Among them, compound 6c displayed powerful anti-cancer activity with the IC50 value of 0.18 muM against HT29 cells, which was significantly better than that of the reference drugs shikonin and CA-4. What’s more, 6c could inhibit tubulin polymerization and compete with [3H] colchicine in binding to tubulin. Further biological studies depicted that 6c can induce cell apoptosis and cell mitochondria depolarize, regulate the expression of apoptosis related proteins in HT29 cells. Besides, 6c actuated the HT29 cell cycle arrest at G2/M phase, and influenced the expression of the cell-cycle related protein. Moreover, 6c displayed potent inhibition on cell migration and tube formation that contributes to the antiangiogenesis. These results prompt us to consider 6c as a potential tubulin polymerization inhibitor and is worthy for further study.

Pterocarpus is one of the most widely used timber resources on the market. But the utilization rate has been low. In order to improve the utilization of Pterocarpus processing residue, as well as explore the reason of its good decay-resistance. In this study, the antifungal mechanism of Peterocarpes spp., aqueous extracts and ethanol extracts of three Pterocarpus species were studied. The antimicrobial active factors were analyzed by gas chromatography-mass spectrometry. Italian poplar (Populus euramevicana cv. ?I-214?) wood was immersed in the extracts and then inoculated with both Coriolus versicolor and Gloeophyllum trabeum. The antimicrobial properties of the extracts were studied, and the mechanism underlying these properties were analyzed using gas chromatography-mass spectrometry. The results showed that the yield of ethanol extracts from the three Pterocarpus species was significantly higher than that of aqueous extracts. Pterocarpus soyauxii and Pterocarpus macarocarpus produced the highest yield of ethanol extracts (28.59%) and aqueous extracts (14.31%), respectively. With increasing concentrations, the antimicrobial activities of aqueous extracts of Pterocarpus angolensis and Pterocarpus macarocarpus gradually increased, while the antimicrobial activity of other extracts remained constant. Gas chromatography-mass spectrometry analysis identified a considerable number of phenols, ketones, amines, and aromatic compounds in all extracts, which is consistent with their antimicrobial activity and suggests synergism among the chemicals.
