New aminophthalides were synthesized from o-formylbenzoic acid and substituted 2-aminothiophenes. Two of these compounds underwent recyclization in boiling Ac2O to give the previously unknown 3-acetoxy-2-(3-cyano-4, 5-dimethylthiophen-2-yl)-1,3-dihydroisoindol-1-one and 3-acetoxy-2-(3-cyano-4,5- tetramethylenethiophen-2-yl)-1,3-dihydroisoindol-1-one. The possible reaction mechanism and factors preventing the recyclization, in particular, the formation of intramolecular hydrogen bonds in the starting phthalides, were discussed. Some reactions of the resulting compounds with C-nucleophiles in trifluoroacetic acid were investigated. Two derivatives containing 4-hydroxy-3,5-di-tert- butylphenyl substituents were studied by X-ray diffraction.

Carbon-13 chemical shifts of the alpha- and beta-carbon atoms for 12 thietane 1,1-dioxides, 9 thietane 1-oxides and 7 thietanes with a variety of 3-substituents are correlated according to the nature of the sulfur atom (Y=sulfone, sulfoxide, sulfide) and the nature of the 3-substituent (X) by the equations deltaalpha=aY+bX and deltabeta=aX+bY, where a and b are parameters characteristic of X and Y.One-bond coupling constants are reported for 21 compounds.The chemical shifts for the alpha- and the beta-carbon atoms of the sulfones show the “four-membered ring sulfone effect” (alpha-carbon unusually deshielded, beta-carbon unusually shielded), but the alpha-carbon-hydrogen coupling constants are similar to those of the sulfoxides and sulfides; the beta-carbon-hydrogen coupling constants are sensitive to the nature of the substituent (X) but no special beta-effect is observed.Comparison of the chemical shifts of the alpha-methylene carbon atoms of 3-phenyl-, 3-(beta-naphthyl)- and 3-(alpha-thienyl)-thietes with those of the corresponding sulfones also reveals the “four-membered ring sulfone effect” cis- and trans-3-substituted thietane 1-oxides may be distinguished by the greater downfield shift for the beta-carbon atom in the trans-isomer.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 496-41-3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 496-41-3, Name is Benzofuran-2-carboxylic acid, molecular formula is C9H6O3

A Pd/Ag bimetallic system has been developed for the decarboxylative allylation of ortho-nitrobenzoic esters in an intramolecular fashion. In contrast to the typical sp2-sp3 cross-coupling approach which requires air and moisture sensitive preformed organometallic reagents, we provide an alternative route to the synthesis of ortho-allyl nitroarenes from the corresponding ortho-nitrobenzoic acid derivatives. The reaction proceeds through a mechanistically distinct decarboxylative metalation pathway. A cooperative reactivity of palladium and silver is crucial for the reaction outcome.

The brown seaweed Sargassum muticum is an invasive species to the coasts of the British Isles, mainland Europe and North America. Attempts at its eradication and control have generally not been successful, although time-consuming and costly. Commercial exploration of this biomass for fuel could encourage its harvesting and control. Anaerobic digestion (AD) has been suggested as one of the most promising methods of exploiting algae for biofuel. The harvesting of S. muticum is seasonal; thus, there will be a need to preserve and store seaweed to supply a year-round anaerobic digestion process. Ensiling is widely used in terrestrial agriculture, but there has been little research on ensiling seaweed. The aims of this research were to: a) study the effect of ensiling on the biomethane potential of S. muticum, b) effect of size reduction prior to ensilage on leachate and other losses during ensiling and c) examine the mass balance and energy losses of ensiling S. muticum. Ensiling was found to be an effective, low energy loss method of preserving seaweed with energy loss from the biomass due to ensiling <8 % of the higher heating value of seaweed feedstock. Ensiling results in losses of salt from the biomass and the virtual total loss of organic sulphur. Size reduction of seaweed prior to ensilage reduced leachate and energy loss from the biomass. Ensiling had no significant effect on methane yield. However, methane yields from S. muticum are low ?0.11 L CH4 g?1 volatile solid (VS) at ~25 % of the theoretical maximum. Further research is needed to establish the reasons for the recalcitrance of S. muticum, but the C:N ratio of S. muticum is low (8:1), and co-digestion with a low nitrogen content substrate such as crude glycerol may be a potential method of improving methane yield. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Electric Literature of 501892-90-6, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.501892-90-6, Name is Methyl 3-bromobenzofuran-5-carboxylate, molecular formula is C10H7BrO3. In a Review，once mentioned of 501892-90-6

Crystalline materials are of crucial importance to the pharmaceutical industry, as a large number of APIs are formulated in crystalline form, occasionally in the presence of crystalline excipients. Owing to their multifaceted character, crystals were found to have strongly anisotropic properties. In fact, anisotropic properties were found to be quite important for a number of processes including milling, granulation and tableting. An understanding of crystal anisotropy and an ability to control and predict crystal anisotropy are mostly subjects of interest for researchers. A number of studies dealing with the aforementioned phenomena are grounded on over-simplistic assumptions, neglecting key attributes of crystalline materials, most importantly the anisotropic nature of a number of their properties. Moreover, concepts such as the influence of interfacial phenomena in the behaviour of crystalline materials during their growth and in vivo, are still poorly understood. The review aims to address concepts from a molecular perspective, focusing on crystal growth and dissolution. It begins with a brief outline of fundamental concepts of intermolecular and interfacial phenomena. The second part discusses their relevance to the field of pharmaceutical crystal growth and dissolution. Particular emphasis is given to works dealing with mechanistic understandings of the influence of solvents and additives on crystal habit. Furthermore, comments and perspectives, highlighting future directions for the implementation of fundamental concepts of interfacial phenomena in the rational understanding of crystal growth and dissolution processes, have been provided.

Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C10H9NO3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 57805-85-3

A series of 3-substituted-benzofuran-2-carboxylic esters was synthesized and evaluated for biological activity as ischemic cell death inhibitors in H9c2 cells and rat primary cardiac myocytes under conditions of oxygen and glucose deprivation. The introduction of a sulfur atom at the three-position substituent of the benzofuran ring markedly improved ischemic cell death inhibitory potency. In particular, 3-[2-(4-nitro-phenylsulfanyl)-acetylamino]-benzofuran-2- carboxylic acid ester (10) (EC50 = 0.532 muM, cell death = 6.18%) and 4-chloro-3-[3-(pyridin-2-ylsulfanyl)-propionylamino]-benzofuran-2-carboxylic ester (18) (EC50 = 0.557 muM, cell death = 7.02%) were shown to be the most potent in this series of benzofuran analogs.

The dianionic species, lithium 2-lithiobenzofuran-3-carboxylate (5) and lithium 3-lithiobenzofuran-2-carboxylate (11b) can be readily generated from the parent acids by reaction with lithium diisopropylamide in tetrahydrofuran at low temperatures.While compound (5) is a useful synthetic intermediate, which reacts efficiently with a number of electrophiles, (11b) instead undergoes rapid opening of the furan ring to give (2-hydroxyphenyl)propynoic acid (10a).By contrast, 5- and 7-methoxybenzofuran-2-carboxylic acids (13a) and (13c) give rise to the dianions (14a) and (14c) which are sufficiently stable at <= -90 deg C to be trapped by aldehydes.The dianion (14b) derived from 6-methoxybenzofuran-2-carboxylic acid (13b), however, suffers rapid ring opening before it can be trapped, even at very low temperatures.A plausible explanation of these observations is given.Metallation of 3-methylbenzofuran-2-carboxylic acid (18) affords the dianion (20), which cannot undergo ring opening and which is a valuable intermediate for the synthesis of a range of 3-substituted benzofuran-2-carboxylic acids.

NMR-based screening of a customized fragment library identified 16 small-molecule hits that bind weakly (KD ? 100 muM to 10 mM) to substrate binding sites of the NS4A-bound NS3 protease of the hepatitis C virus (HCV). Analogues for five classes of NMR hits were evaluated by a combination of NMR and biochemical data yielding SAR and, in most cases, optimized hits with improved potencies (KD ? KI ? 40 muM to mM). NMR chemical shift perturbation data were used to establish the binding location and orientation of the active site directed scaffolds in these five analogue series. Two of these scaffolds, which bind the enzyme at the proximal S1-S3 and S2? substrate binding sites, were linked together producing competitive inhibitors of the HCV NS3 protease with potencies in the micromolar range. This example illustrates that the low molecular weight scaffolds discovered from structure-based NMR screening can be optimized with focused structure-guided chemistry to produce potent nonpeptidic small-molecule inhibitors of the HCV NS3 protease.

The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.
