Phenol is commercially produced through cumene hydroperoxide (CHP) cleavage in kettle reactor, having the disadvantages of hazard potential, low selectivity, low efficiency and complicated process. In the study, microchannel reactor has been introduced into the decomposition using sulfuric acid as the catalyst. The influences of various reaction conditions, including temperature, the ratio of sulfuric acid/CHP and residence time, on the reaction have been studied. Compared with kettle reactor, the present process can afford almost quantitative yield of phenol with reduced acid amount and shortened reaction time under higher reaction temperature. The microchannel process can also provide higher security of CHP cleavage. The microtechnology probably gives an alternative protocol for the production of phenol through CHP decomposition. In addition, the possible main reaction pathways for the CHP cleavage in microchannel reactor have been discussed according to the obtained results.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 496-41-3, Benzofuran-2-carboxylic acid, introducing its new discovery.

Imidazolidine and 1,4-diazepane analogs of N-(2-benzofuranyl)methyl- N?-(4-alkoxybenzyl)piperazines were prepared to explore the effect of ring contraction and expansion on sigma receptor affinity and subtype selectivity within a series of cyclic diamines. In vitro receptor binding assays revealed that all cyclic vicinal diamines possessed affinity and selectivity for sigma1 receptors. The imidazolidines possessed nanomolar sigma1 affinities (Ki = 6.45-53.5 nM), and relatively low levels of subtype selectivity (sigma2/sigma1 = 58-237). However, the piperazines and diazepanes achieved picomolar sigma1 interactions, with Ki ranges of 0.05-10.28 and 0.10-0.194 nM, respectively. Moreover, the piperazines and diazepanes showed excellent discrimination over the sigma2 receptor, with sigma1 selectivities of 143-16140 and 220-11542, respectively.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Application In Synthesis of 3-Hydroxyisobenzofuran-1(3H)-one, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one, molecular formula is C8H6O3

This work reports the design and synthesis of novel alkylamides, characterized by a dibenzo[a,d] cycloheptene nucleus, as melatonin (MLT) receptor ligands. The tricyclic scaffold was chosen on the basis of previous quantitative structure-activity studies on MT1 and MT2 antagonists, relating selective MT2 antagonism to the presence of an aromatic substituent out of the plane of the MLT indole ring. Some dibenzo seven-membered structures were thus selected because of the noncoplanar arrangement of their benzene rings, and an alkylamide chain was introduced to fit the requirements for MLT receptor binding, namely, dibenzocycloheptenes with an acylaminoalkyl side chain at position 10 and dibenzoazepines with this side chain originating from the nitrogen atom bridging the two phenyl rings. Binding affinity at human cloned MT1 and MT2 receptors was measured by 2[125I] iodomelatonin displacement assay and intrinsic activity by the GTPgammaS test. The majority of the compounds were characterized by higher affinity at the MT2 than at the MT 1 receptor and by very low intrinsic activity values, thus confirming the importance of the noncoplanar arrangement of the two aromatic rings for selective MT2 antagonism. Dibenzocycloheptenes generally displayed higher MT1 and MT2 affinity than dibenzoazepines. N-(8-Methoxy-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-10-ylmethyl)propionamide (4c) and -butyramide (4d) were the most selective MT2 receptor antagonists of the series, with MT2 receptor affinity comparable to that of melatonin and as such among the highest reported in the literature for MLT receptor antagonists. The acetamide derivative 4b produced a noticeable reduction of GTPgammaS binding at MT2 receptor, thus being among the few inverse agonists described.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3199-61-9, name is Ethyl benzofuran-2-carboxylate, introducing its new discovery. Formula: C11H10O3

Despite being one of the most important and frequently run chemical reactions, the synthesis of amide bonds is accomplished primarily by wasteful methods that proceed by stoichiometric activation of one of the starting materials. We report a nickel-catalyzed procedure that can enable diverse amides to be synthesized from abundant methyl ester starting materials, producing only volatile alcohol as a stoichiometric waste product. In contrast to acid- and base-mediated amidations, the reaction is proposed to proceed by a neutral cross coupling-type mechanism, opening up new opportunities for direct, efficient, chemoselective synthesis.

Reference of 17403-47-3, 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.17403-47-3, Name is 5-Nitro-2,3-dihydrobenzofuran, molecular formula is C8H7NO3. In a article£¬once mentioned of 17403-47-3

Novel substituted 2,3-dihydrobenzofuran-7-carboxamide (DHBF-7-carboxamide) and 2,3-dihydrobenzofuran-3(2H)-one-7-carboxamide (DHBF-3-one-7-carboxamide) derivatives were synthesized and evaluated as inhibitors of poly(ADP-ribose) polymerase-1 (PARP-1). A structure-based design strategy resulted in lead compound 3 (DHBF-7-carboxamide; IC50 = 9.45 muM). To facilitate synthetically feasible derivatives, an alternative core was designed, DHBF-3-one-7-carboxamide (36, IC50 = 16.2 muM). The electrophilic 2-position of this scaffold was accessible for extended modifications. Substituted benzylidene derivatives at the 2-position were found to be the most potent, with 3?,4?-dihydroxybenzylidene 58 (IC50 = 0.531 muM) showing a 30-fold improvement in potency. Various heterocycles attached at the 4?-hydroxyl/4?-amino of the benzylidene moiety resulted in significant improvement in inhibition of PARP-1 activity (e.g., compounds 66-68, 70, 72, and 73; IC50 values from 0.718 to 0.079 muM). Compound 66 showed selective cytotoxicity in BRCA2-deficient DT40 cells. Crystal structures of three inhibitors (compounds (-)-13c, 59, and 65) bound to a multidomain PARP-1 structure were obtained, providing insights into further development of these inhibitors.

1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, belongs to benzofurans compound, is a common compound. Formula: C10H12O2In an article, once mentioned the new application about 1563-38-8.

Cell-wall components (cellulose, hemicellulose (oat spelt xylan), lignin (Organosolv)), and model compounds (levoglucosan (an intermediate product of cellulose decomposition) and chlorogenic acid (structurally similar to lignin polymer units)) have been investigated to probe in detail the influence of potassium on their pyrolysis behaviours as well as their uncatalysed decomposition reaction. Cellulose and lignin were pretreated to remove salts and metals by hydrochloric acid, and this dematerialized sample was impregnated with 1% of potassium as potassium acetate. Levoglucosan, xylan and chlorogenic acid were mixed with CH3COOK to introduce 1% K. Characterisation was performed using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). In addition to the TGA pyrolysis, pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS) analysis was introduced to examine reaction products. Potassium-catalysed pyrolysis has a huge influence on the char formation stage and increases the char yields considerably (from 7.7% for raw cellulose to 27.7% for potassium impregnated cellulose; from 5.7% for raw levoglucosan to 20.8% for levoglucosan with CH3COOK added). Major changes in the pyrolytic decomposition pathways were observed for cellulose, levoglucosan and chlorogenic acid. The results for cellulose and levoglucosan are consistent with a base catalysed route in the presence of the potassium salt which promotes complete decomposition of glucosidic units by a heterolytic mechanism and favours its direct depolymerization and fragmentation to low molecular weight components (e.g. acetic acid, formic acid, glyoxal, hydroxyacetaldehyde and acetol). Base catalysed polymerization reactions increase the char yield. Potassium-catalysed lignin pyrolysis is very significant: the temperature of maximum conversion in pyrolysis shifts to lower temperature by 70 K and catalysed polymerization reactions increase the char yield from 37% to 51%. A similar trend is observed for the model compound, chlorogenic acid. The addition of potassium does not produce a dramatic change in the tar product distribution, although its addition to chlorogenic acid promoted the generation of cyclohexane and phenol derivatives. Postulated thermal decomposition schemes for chlorogenic acid are presented.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C9H6O3. Introducing a new discovery about 496-41-3, Name is Benzofuran-2-carboxylic acid

Here, we described the structural modification of previously identified mu opioid receptor (MOR) antagonist NAN, a 6alpha-N-7?-indolyl substituted naltrexamine derivative, and its 6beta-N-2?-indolyl substituted analogue INTA by adopting the concept of “bivalent bioisostere”. Three newly prepared opioid ligands, 25 (NBF), 31, and 38, were identified as potent MOR antagonists both in vitro and in vivo. Moreover, these three compounds significantly antagonized DAMGO-induced intracellular calcium flux and displayed varying degrees of inhibition on cAMP production. Furthermore, NBF produced much less significant withdrawal effects than naloxone in morphine-pelleted mice. Molecular modeling studies revealed that these bivalent bioisosteres may adopt similar binding modes in the MOR and the “address” portions of them may have negative or positive allosteric modulation effects on the function of their “message” portions compared with NAN and INTA. Collectively, our successful application of the “bivalent bioisostere concept” identified a promising lead to develop novel therapeutic agents toward opioid use disorder treatments.

The one-pot synthesis of novel 1,4-disubstituted 1,2,3-triazoles from homopropargyl alcohol backbones is described. The key intermediates 2-benzothiophenyl 1a and 2-benzofuranyl 1b substituted homopropargyl alcohols were synthesized starting from their corresponding carboxyaldehyde derivatives. The racemic heteroaryl-substituted homopropargyl alcohol derivatives are successfully resolved to give the corresponding enantiopure acetates and the alcohols with 84-99% ee by applying chemoenzymatic methods using various lipases. Enantiomerically enriched homopropargyl alcohol derivatives were reacted with various aromatic and aliphatic halides and sodium azide via a one-pot synthesis method and novel chiral benzothiophenyltriazoles 3a-9a and benzofuranyltriazoles 3b-9b were constructed without the isolation of potentially unstable organic azide intermediates.
