1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.HPLC of Formula: 66943-05-3

Mendez, Jesus et al. published their research in Microchemical Journal in 1969 | CAS: 6972-61-8

3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Formula: C11H12O4

Ma, Mingxuan et al. published their research in Chromatographia in 2017 | CAS: 66943-05-3

1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.HPLC of Formula: 66943-05-3

Abstract: Aza-15-crown-5-capped (3-(C-methylcalix[4]resorcinarene)-2-hydroxypropoxy)-propylsilyl (MCR-HP)-appended silica particles (15C5-MCR-HPS), a new type of substituted C-methylcalix[4]resorcinarene (MCR)-bonded chiral stationary phase (CSP) for high-performance liquid chromatog. (HPLC), have been synthesized by reaction of bromoacetate-substituted MCR-HPS with excessive aza-15-crown-5 in anhydrous acetonitrile in the presence of potassium carbonate. The bonded phase 15C5-MCR-HPS is characterized by elemental anal. and further evaluated by separating several disubstituted benzenes and some chiral drug compounds in HPLC. The new CSP has a chiral selector with two recognition sites: 15-crown-5 and MCR-HP, which can provide cooperative multiple interactions with solutes to enhance chiral recognition and to improve chromatog. separation The chromatog. evaluation results show that 15C5-MCR-HPS has excellent selectivity for the separation of aromatic positional isomers and enantiomers of some chiral compounds under multiple-mode mobile phase conditions including normal phase, reversed phase, and polar organic mobile phase conditions.

Sahoo, Manoj K. et al. published their research in Green Chemistry in 2017 | CAS: 56619-93-3

N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Formula: C12H17NO2

A unified strategy for silver-, base-, and oxidant-free direct arylation of C-H bonds was written by Sahoo, Manoj K.;Midya, Siba P.;Landge, Vinod G.;Balaraman, Ekambaram. And the article was included in Green Chemistry in 2017.Formula: C12H17NO2 This article mentions the following:

Herein, a dual catalytic approach for room temperature direct arylation of C-H bonds with aryldiazonium salts as a simple aryl group donor, also working as an internal oxidant via C-N2 bond cleavage is reported. This unified strategy has been achieved by the synergistic combination of visible-light metal-free photoredox and palladium catalysis under silver-, base- and/or additive-free conditions. The broad substrate scope, functional group tolerance, excellent regioselectivity and redox-neutral conditions of this process make it attractive for the effective synthesis of a wide range of important N-heterocyclic commodities such as dibenzo[b,d]azepine, carbazole and phenanthridine. In the experiment, the researchers used many compounds, for example, N-(3-Methoxyphenyl)pivalamide (cas: 56619-93-3Formula: C12H17NO2).

CoII and MnIII complexes with aza-crown substituted, unsym. bis-Schiff base ligands were synthesized starting from monoaza-15-crown-5 or benzo-10-aza-15-crown-5. The saturated oxygen uptake of the CoII complexes [CoL1]-[CoL4] in diethyleneglycol/dimethyl ether solution were determined at different temperatures The oxygenation constant (Ko2) and thermodn. parameters (ΔH°, ΔS°) were calculated The MnIII complexes ([MnL1Cl]-[MnL4Cl]) were employed to catalyze styrene oxidation using mol. oxygen at ambient temperature and pressure. The modulation of O2-binding capabilities and catalytic oxidation performance by the aza-crown ether pendant groups in [ML3] and [ML4] were studied as compared with the parent complexes [ML1] and morpholino-substituted analog [ML2]. The dioxygen affinities and catalytic oxidation activities of [CoL3] and [CoL4] were much more enhanced by aza-crown pendants. Moreover, the O2-binding capabilities of [CoL3] and [CoL4] were also improved by adding alkali metal cations (Li+, Na+ and K+) to the system, and adding Na+ shows the most significant enhancement of dioxygen affinities. Likewise, [MnL3Cl] and [MnL4Cl] exhibit the best catalytic activities: the conversion of styrene to benzaldehyde are up to 41.2% and 45.8% with >99% selectivity.

Phosphatidylinositol 3-kinase α (PI3Kα) is the most frequently mutated kinase in human cancers, making it an attractive therapeutic target for cancer treatment. The authors identified a structurally novel PI3Kα H1047R mutant inhibitor Hit-01 (5,7-dichloro-2,3-di(furan-2-yl)quinoxaline) (EC50 = 76.0 μM) through a high-throughput screening campaign. Chem. optimizations enabled the authors to discover compound 7b (6-bromo-7-(2-fluorophenyl)-2,3-di(furan-2-yl)quinoxaline), which strongly inhibited PI3Kα H1047R mutant with an EC50 value of 0.137 μM, over 500-fold more potent than Hit-01. Western blotting anal. suggested that 7b could decrease the phosphorylation level of p-AKT, another proof that 7b inhibited PI3Kα H1047R function. Cell viability assay revealed that 7b inhibited HCT116 cancer cell growth with an IC50 value of 11.23 μM. In addition, 7b was found to arrest cell cycle at G1 phase and induce cell apoptosis via up-regulation of caspase-3, caspase-8 and caspase-9 protein expressions.

Poly(ionic liquid)s with branched side chains: polymer design for breaking the conventional record of ionic conductivity was written by Ikeda, Taichi. And the article was included in Polymer Chemistry in 2021.Application In Synthesis of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol This article mentions the following:

Poly(ionic liquid)s with non-branched, di-branched, and tri-branched side chains were synthesized using cationic glycidyl triazolyl polymers (GTPs). Based on the analyses of these cationic GTPs, the effects of side-chain branching on phys. properties, such as glass transition temperature and ionic conductivity, were discussed. It was confirmed that the ionic conductivity increased with the degree of side-chain branching. Despite being a high-mol.-weight polymer (1.9 x 106 Da), GTP with tri-branched side chains exhibited a high ionic conductivity of 3.6 x 10-5 M at 25°C under dry conditions, which is higher than the benchmark value of the conventional poly(ionic liquid)s proposed by Shaplov, Marcilla, and Mecerreyes (3.0 x 10-5 M at 25°C, dry conditions, mol. weight >105 Da). From the anal. based on the electrode polarization model, the higher ionic conductivity of cationic GTPs with branched side chains can be attributed to their higher conducting ion mobility in the polymer matrix. These results indicate that side-chain branching is effective in breaking the conventional limit of ionic conductivity of poly(ionic liquid)s.
