Photochemical Ring Contraction of 5,5-Dialkylcyclopent-2-enones and in situ Trapping by Primary Amines was written by Jeremias, Noah;Peschel, Martin T.;Jaschke, Constantin;de Vivie-Riedle, Regina;Bach, Thorsten. And the article was included in Journal of Organic Chemistry.Formula: C3H9NO The following contents are mentioned in the article:

If substituted in the 5,5-position, cyclopent-2-enones undergo a smooth photochem. rearrangement to ketenes. A concomitant cyclopropane formation occurs due to a 1,3-shift of the C5 carbon atom from the carbonyl carbon atom (C1) to carbon atom C3. In this study, the cyclopropyl-substituted ketene intermediates were trapped in situ by primary amines providing an efficient entry into 2,2-disubstituted cyclopropaneacetic amides (24 examples, 49-95% yield). A remarkable feature of the reaction is the fact that the photochem. rearrangement can occur from either the first excited singlet (S₁) or the resp. triplet state (T₁). In line with exptl. results (triplet quenching, sensitization), XMS-CASPT2 calculations support the existence of efficient reaction pathways to the intermediate ketene both on the singlet and on the triplet hypersurface. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Formula: C3H9NO).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C3H9NO

NADES-based surfactant-free microemulsions for solubilization and extraction of curcumin from Curcuma Longa was written by Huber, Verena;Muller, Laurie;Degot, Pierre;Touraud, Didier;Kunz, Werner. And the article was included in Food Chemistry in 2021.HPLC of Formula: 33171-05-0 The following contents are mentioned in the article:

A choline chloride + lactic acid (1:1) natural deep eutectic solvent (NADES) is used as an adjuvant to ethanol/triacetin mixtures to solubilize and extract curcumin from Curcuma Longa. The obtained NADES/ethanol/triacetin mixtures are homogeneous, transparent and of low viscosity even in the absence of water. Dynamic light scattering revealed significant nanostructures, typical of surfactant-free microemulsions. A twofold increase of curcumin solubility and remarkable extraction power (yield of ∼90%) can be achieved in the ternary system including the NADES, although curcumin is hydrophobic and the used NADES are very polar. Due to the elevated solubility of curcumin, more extraction cycles can be made than in the previously published aqueous systems with the same amount of solution As a result, less solvent is required to achieve the same extraction yield. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0HPLC of Formula: 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.HPLC of Formula: 33171-05-0

Frother function-structure relationship: Dependence of CCC95 on HLB and the H-ratio was written by Finch, James A.;Zhang, Wei. And the article was included in Minerals Engineering in 2014.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Although the number and diversity of com. frothers has steadily increased to meet flotation industry demands, frother selection is still mainly empirical. As part of a general structure-property study, the paper presents a correlation between the critical coalescence concentration (CCC95) and H-ratio for surfactants used as flotation frothers. The CCC95 were determined in 0.8 m³ mech. flotation cell. The H-ratio was a substitution of hydrophile-lipophile balance (HLB) and determined through high resolution proton NMR (¹H NMR) spectrometry. A large data set, consisting of 45 surfactants from four frother families, was used to develop the correlation. It is shown that the H-ratio can substitute for HLB. The potential of NMR both to identify the frother family and to derive the H-ratio in predicting CCC95 for com. frothers is discussed. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Category: ethers-buliding-blocks).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: ethers-buliding-blocks

And the article was included in Journal of the American Chemical Society in 2020.SDS of cas: 1003858-50-1 The following contents are mentioned in the article:

In the presence of Pd(OAc)₂ and a bis(hydroxyphenyl)salen cobalt complex acting as an electron transfer mediator, allylic enallenyl ethers such as I underwent diastereoselective tandem aerobic coupling and cyclization reactions with arylboronic acid neopentyl glycol esters to yield (arylmethyl)dialkenyldihydropyrans such as II and a dialkenyltetrahydropyridine as the cis-diastereomers in >8:1 dr. The mechanism of the reaction was studied using kinetic isotope effect (KIE) experiments, reactions of substrates with altered structures, and calculations of potential transition state structures and their energies; the alkene moiety of the eneallene is necessary both to facilitate C-H bond cleavage and to control product diastereoselectivity, while KIE indicated that C-H bond cleavage is the rate-limiting step.

Fluoroalkylation of Various Nucleophiles with Fluoroalkyl Sulfones through a Single Electron Transfer Process was written by Xiao, Pan;Ni, Chuanfa;Miao, Wenjun;Zhou, Min;Hu, Jingyu;Chen, Dingben;Hu, Jinbo. And the article was included in Journal of Organic Chemistry in 2019.Reference of 103-16-2 The following contents are mentioned in the article:

The fluoroalkylation of various nucleophilic reagents with (phenylsulfonyl)difluoromethyl (PhSO₂CF₂)-substituted phenanthridines was achieved to give fluorinated phenanthridine derivatives, which enables the construction of both carbon-heteroatom and carbon-carbon bonds via the substitution of the phenylsulfonyl group. Mechanistic studies indicated that these reactions proceed through a unimol. radical nucleophilic substitution (S_RN1) mechanism. It is worthwhile noting that in the cases of O-nucleophiles (t-BuO^– and PhO^–), the addition of t-BuOK/PhCHO could significantly promote the reactions, due to the in situ formation of a highly reactive electron donor species through the interaction of t-BuOK, PhCHO, and the solvent DMF, which can effectively initiate the single electron transfer process.

Triple-neg. breast cancer (TNBC) is the most aggressive subtype of breast cancer. Many studies have shown a significant increase in the marker signal of the receptor for advanced glycation end-products (RAGE) with the malignant progression of tumor growth, metastasis and recurrence of breast cancer, including TNBC of primary tumors and lymph node metastases. Azeliragon is a RAGE inhibitor and it has been shown to actively inhibit the TNBC cell line, SUM149 (IC₅₀ = 5.292 ± 0.310 μM). In order to develop a new anti-TNBC agent, we designed, synthesized and screened 26 Azeliragon triazole analogs to determine their anti-TNBC activities in vitro. The most active compound was KC-10 (3-(4-(5-butyl-1-(4′-chloro-[1,1′-biphenyl]-4-yl)-1H-1,2,4-triazol-3-yl)phenoxy)-N, N-diethylpropan-1-amine) with an IC₅₀ value of 0.220 ± 0.034 μM.
