Variable temperature (1)H and (13)C n.m.r. studies in CFCl3/CDCl3 of equilibria in 2-substituted- and 2-substituted-4-methyl-tetrahydropyranes have given conformational enthalpy differences and conformational entropy differences for chloro, methoxy, hydroxy and methylamino substituents.For DeltaHoa->e, the values obtained, in kcal /mol, were 1.67 (Cl), 0.03 (OCH3), -0.63 (OH) and -1.75 (NHCH3); for DeltaSoa->e the values obtained, in cal K-1mol-1 were -1.69 (Cl), -2.52 (OCH3), -2.50 (OH) and -0.60 (NHCH3).The trend in DeltaHo values confirms the importance of antiperiplanar n-?* stabilisation as a contributor to the explanation of the anomeric effect, and supports a suggestion that endo- and exo-anomeric effects which occur in the same conformation are competitive.A variable temperature (13)C n.m.r. study of (Me-(13)C)-4-methyl-tetrahydropyran in CD2Cl2 has given a conformational enthalpy difference (DeltaHoa->e) of -1.86 kcal/mol and a conformational entropy difference (DeltaSoa->e) of -0.07 cal K-1mol-1 for a methyl substituent at the 4-position of a tetrahydropyran.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7525-64-6 is helpful to your research., Application of 7525-64-6

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 50675-18-8, Name is Tetrahydropyran-4-carbaldehyde, molecular formula is C6H10O2. In a Article，once mentioned of 50675-18-8, Electric Literature of 50675-18-8

All-carbon quaternary stereocenters are versatile building blocks, and their asymmetric construction has attracted much attention. Herein, we disclose an axial-to-central chirality transfer strategy for the synthesis of chiral quaternary stereocenters via dearomatization of (S)-BINOLs. The reaction proceeded smoothly with a wide range of propargyl carbonates to afford chiral spiro-compounds in high yields with excellent enantioselectivities. In addition, the strategy was extended to kinetic resolution of rac-BINOLs albeit with moderate s value.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 50675-18-8 is helpful to your research., Electric Literature of 50675-18-8

The intramolecular cycloaddition reactions of the nitrile oxides 30 a-d, 35, 36, and 47, obtained in situ from the 2,5-difunctional furan hydroximoyl chlorides 12a, b, 18 and the nitro compounds 9c, d, 21, 29, are described.With 30c the expected isoxazolofuranophane of type 31 is formed in acceptable yield; the additionally formed regioisomer 32c and the dimer 34c are very minor products in this case.Whereas the highest homologue 30d gives a complex product mixture with small amounts of 31d and the macrocycle 34d as the only identified compounds, the derivatives bearing a shorter side chain (30a, b; n = 1, 2) give rise to the exclusive reaction of the dipole with a double bond of the furan system(to give 33a, b).The same behavior is observed in the case of the electronically and sterically modified dipole systems 35/36 and 47, resp.; in spite of the much more favorable conditions for the formation of cyclophanes the cycloadditions result in the exclusive formation of the heterotricycles 41, 42 and 49.Possible preparative applications of the isomeric cycloaddition compounds are discussed. – Key Words: 1,3-Dipolar cycloadditions, intramolecular / Nitrile oxides / Regioselectivity / Furanophanes

Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.134419-59-3, C6H12O4S.

In a Article，once mentioned of 61363-56-2, Application In Synthesis of 2H-Pyran-3,5(4H,6H)-dione

A copper-catalyzed sequential arylation and intramolecular annulation of 2-(2-bromophenyl)-2,3-dihydroquinazolin-4(1H)-ones with alkyl amidines has been developed for the synthesis of 6-alkyl 11bH-quinazolino[3,4-a]quinazolin-13(12H) -ones (3) in moderate to good yields. However, the arylated products N-(2-(4-oxo-1,2,3,4-tetrahydroquinazolin-2-yl)phenyl)benzimidamides (4) are isolated when aryl amidines are used in the transformation.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 2H-Pyran-3,5(4H,6H)-dione, you can also check out more blogs about61363-56-2

COA of Formula: C9H16O2, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. 3301-94-8, C9H16O2. A document type is Article, introducing its new discovery.

Plants of the Lavandula genus have been widely used in folk and traditional medicine. The aim of this study was to evaluate the qualitative and quantitative chemical composition of the essential oil of the aerial parts of Lavandula atriplicifolia (EOAPLA) grown in Saudi Arabia and its potential cytotoxicity to cancer cell lines. The essential oil was characterized and quantified by GC?MS and GC-FID. The potential cytotoxicity of the essential oil was evaluated against colorectal (LoVo) and hepatocellular (HepG2) carcinoma cell lines by using the MTT and lactate dehydrogenase (LDH) cytotoxicity assays. A total of 36 compounds were identified that constituted 92.3% of the total oil. The chemotype of the species was dominated by C-10 massoia lactone (46.65%) as the major compound followed by oxygenated monoterpenes (28.43%). This is the first report to describe the presence of the rare compound massoia lactone in the essential oils from Lavandula species. The data revealed that EOAPLA inhibited the growth of LoVo and HepG2 cells in a dose-dependent manner. Treatment with 10 mug/mL EOAPLA for 2 days resulted in significant damage to LoVo cells in comparison with the control. In contrast to the control cells, the LoVo cells showed morphological alterations such as cytoplasmic condensation, shrinkage, and the formation of debris. Moreover, EOAPLA treatment induced apoptosis in LoVo cells since it increased the expression of caspase 3/7. The cytotoxic and anti-proliferative properties of EOAPLA make it a good candidate for treatment of various cancers.
