One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: benzofuran, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 89424-83-9, Name is 1,3-Dihydroisobenzofuran-5-carbaldehyde, molecular formula is C9H8O2

(Chemical Equation Presented) Diastereoselective aldol reactions of chlorotitanium enolate derived from 20-hydroxypropiophenone are reported. The corresponding aldol products were prepared in moderate to excellent yields. In general, the expected syn diastereoisomers were obtained. Utilization of trans-cinnamaldehyde, 4-methoxybenzaldehyde, and 4-butoxybenzaldehyde in the aldol reaction afforded mainly unexpected anti aldol adducts. Three reasonable transition states for the reactions have been assigned to explain the diastereochemical outcome of the process depending on substitution pattern on aldehydes. This transition-state model using alkoxy at the 4-position of aromatic aldehydes considerably amplifies the synthetic utility of aldol reaction in diastereoselective synthesis.

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, 18959-30-3, name is 4,5-Difluorophthalic Anhydride, introducing its new discovery. Recommanded Product: 18959-30-3

In continuing studies to develop low melt viscosity phenylethynyl end-capped imide oligomers for aerospace applications, new kinds of all-aromatic phenylethynyl-terminated imide oligomers were prepared by the reaction of 3,3?,4,4?-benzophenonetetracarboxylic dianhydride (BTDA) or biphenylenetetracarboxylic dianhydride (s-BPDA) with 2,5-bis(4-aminophenoxy)-biphenyl (p-TPEQ) and 4-phenylethynylphthalic anhydride (PEPA) or 4-(1-phenylethynyl)1,8-naphthalic anhydride (PENA). The oligomers bearing pendant phenyl groups exhibit much lower melt viscosities at low temperatures, and thus provide wide processing window. The thermal curing process of the oligomers was investigated with DSC. The tensile and thermal properties of the cured films were evaluated. Oligomers derived from PENA cured at lower temperatures and the corresponding cured polymers show better hydrolytic stability than those of PEPA. Results showed that the utilization of diamine monomer (p-TPEQ) can improve the processability and solubility of phenylethynyl-terminated imide oligomers without sacrificing their thermo-oxidative stability.

4265-25-2, Name is 2-Methylbenzofuran, belongs to benzofurans compound, is a common compound. Recommanded Product: 2-MethylbenzofuranIn an article, once mentioned the new application about 4265-25-2.

A novel series of 4,5,6,7-tetrahydro-1H-benzimidazole derivatives 4, 5, 6 and 7 was prepared and evaluated for activities as 5-hydroxytryptamine (5- HT3) receptor antagonists which may be useful for the treatment of irritable bowel syndrome (IBS) as well as nausea and vomiting associated with cancer chemotherapy. These compounds were designed by modifying the aromatic- carbonyl part of N-(2-methoxyphenyl)-4,5,6,7-tetrahydro-1H-5- benzimidazolylcarboxamide 3, leaving the imidazole moiety unchanged as the amine part. The indole derivatives 7d, g, h and indolizine derivatives 7k, 1 were found to be highly potent on the von Bezold-Jarisch (B.J.) reflex test with ID50 values of below 0.1 mug/kg, and the indoline derivative 6c, indole derivatives 7a, d, g, benzofurane derivative 7j and indolizine derivative 7k were observed to be very potent on the colonic contraction with IC50 values of below 0.1 muM. In particular, 71 was the most potent on the B.J. reflex (ID50 = 0.018 mug/kg), approximately 200 and 50 times more potent than ondansetron 1 and granisetron 2, and 7k was the most potent on the colonic contraction (IC50 = 0.011 muM), approximately 70 and 6 times more potent than 1 and 2, respectively.

The development of a solution-phase approach to the rapid, parallel synthesis of highly functionalized piperazinones in only four steps starting from N-Boc-iminodiacetic acid is detailed. The efforts represent the extension of the solution-phase synthesis of combinatorial libraries from N-Boc-iminodiacetic acid to non-amide-based libraries where simple liquid-liquid extractions are employed to purify all reaction products. This methodology was applied to the synthesis of a diverse 150-member library with substituents in three positions of the piperazinone core. Screening results from a luciferase reporter assay indicate that a number of library members are novel repressors of LEF-1/beta-catenin-mediated transcription, and may be effective agents against colorectal tumors. Two secondary libraries (100 members each) designed from these lead structures were synthesized and screened, providing additional active agents and insight into key structure-activity relationships in the series. These compounds represent only the second class of small molecules which repress transcription of reporter genes containing LEF-1 responsive elements, and the first group not based on DNA minor-groove-binding agents.
