Enhanced performance of lipase-catalyzed kinetic resolution of secondary alcohols in monoether-functionalized ionic liquids was written by Zhou, Hancheng;Chen, Jin;Ye, Linmin;Lin, Haiqiang;Yuan, Youzhu. And the article was included in Bioresource Technology in 2011.Application of 6294-17-3 The following contents are mentioned in the article:

Several cationic monoether-functionalized ionic liquids (MEF-ILs) with different substituents were synthesized and used as media for kinetic resolution of secondary alcs. catalyzed by several lipases. The results indicate that Novozym 435 (an immobilized Candida antarctica Lipase B) had higher efficiency compared to other lipases in deracemization. The alkyl substituents at the 2- and 3-positions in the imidazolium ring of MEF-ILs were found to contribute to the increased enantioselectivity and enhancement of the reaction rate, resp., while the higher stereo-hindrance of ether bonds decreased the activity. An enantioselectivity higher than 99% with 50% conversion of rac-1-phenylethanol was achieved using the catalyst system comprised of Novozym 435 and the MEF-IL 1-(3-ethoxypropyl)-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide. The catalytic system could be separated and reused without considerable activity loss. MEF-ILs can be a new class of enzyme-benign media suitable for lipase-catalyzed kinetic resolution of secondary alcs. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Application of 6294-17-3).

1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Application of 6294-17-3

A series of new 6H-benzofuro[3, 2-c]chromenes (BFC, pterocarpans) with structure-activity relationships were investigated for their potential use in osteoporosis treatment. One of the BFCs 3-piperidylethoxypterocarpan 20 promotes osteoblast differentiation and mineralization at a dose as low as 1 pM via activation of ER/P38MAPK/BMP-2 pathway. When evaluated for in-vivo osteogenic activity in female Sprague-Dawley rats, BFC 20 increased bone mineral d. and new bone formation, compared with control at 1.0 and 10.0 mg/kg/body weight by oral gavage for 30 days. The compound was devoid of any uterotrophic effect and led to the new bone formation in adult ovariectomized osteopenic rats. BFC 20 compound also inhibited bone resorption by reducing Ovx induced increase in urinary CTx, thus exhibiting both bone anabolic and anti-catabolic action. Finally, BFC 20 treatment to Ovx rats led to improved trabecular microarchitectural restoration and exhibited therapeutic potential as a dual acting anti-osteoporotic agent for the management of osteoporosis. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5HPLC of Formula: 95-88-5).

Electrocatalytic synthesis of α,α-gem-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation was written by Zhou, Bei;He, Yu-Juan;Tao, Yun-Feng;Liu, Lan-Xiang;Hu, Min;Chang, Zu-Hui;Lei, Hong;Lin, Jun;Lin, Tong;Du, Guan-Ben. And the article was included in Green Chemistry in 2022.COA of Formula: C6H9ClO3 The following contents are mentioned in the article:

A novel, environmentally friendly electrocatalytic process was developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing alkali halide salts. The gem-dihalides had the same or different halogens on the same carbon, depending on the reactant and inorganic halide salt used. An electron-withdrawing group, such as carbonyl, located at the α-site of mono-halogenated carbon, was essential to the reaction. The electrosyntheses were performed under ambient conditions without inert gas protection and displayed yields of about 80%. This method avoided the classical haloform elimination reaction. However, when the aqueous solution contained NaOH, two α-mono-halide ketone mols. had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3COA of Formula: C6H9ClO3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C6H9ClO3

Extracting ubiquitous atm. water is a sustainable strategy to enable decentralized access to safely managed water but remains challenging due to its limited daily water output at low relative humidity (≤30% RH). Here, we report super hygroscopic polymer films (SHPFs) composed of renewable biomasses and hygroscopic salt, exhibiting high water uptake of 0.64-0.96 g g^-1 at 15-30% RH. Konjac glucomannan facilitates the highly porous structures with enlarged air-polymer interfaces for active moisture capture and water vapor transport. Thermoresponsive hydroxypropyl cellulose enables phase transition at a low temperature to assist the release of collected water via hydrophobic interactions. With rapid sorption-desorption kinetics, SHPFs operate 14-24 cycles per day in arid environments, equivalent to a water yield of 5.8-13.3 L kg^-1. Synthesized via a simple casting method using sustainable raw materials, SHPFs highlight the potential for low-cost and scalable atm. water harvesting technol. to mitigate the global water crisis.

And the article was included in Sensors and Actuators, B: Chemical in 2019.Application of 122-18-9 The following contents are mentioned in the article:

The introduction of advanced nanocrystals and mediator is crucial for signal amplification of electrochem. immunosensors due to trace amounts of analytes in real samples. Herein, a novel ultrasensitive label-free electrochem. immunosensor was constructed to monitor carbohydrate antigen 15-3 (CA15-3) based on dendritic Au@Pt core-shell nanocrystals (Au@Pt NCs) uniformly dispersed with ferrocene-grafted-chitosan (Fc-g-CS), where Au@Pt NCs were prepared with hexadecyldimethyl benzyl ammonium chloride (HDBAC) as the growth-directing agent via a simple one-pot wet-chem. strategy. More notably, Fc grafted with CS would dramatically improve the stability and the Fc-g-CS enlarged sp. surface area and behaved as dispersing agent for the Au@Pt NCs to greatly boost the electrochem. signals and improve the biocompatibility. The resulting immunosensor displayed wider linear range of 0.5-200 U mL^-1 and lower detection limit of 0. 17 U mL^-1, which was further explored for detecting CA15-3 in serum sample with highly acceptable results. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Application of 122-18-9).

And the article was included in Journal of Medicinal Chemistry in 2019.HPLC of Formula: 638-07-3 The following contents are mentioned in the article:

The mechanism-based risk for hyperkalemia has limited the use of mineralocorticoid receptor antagonists (MRAs) like eplerenone in cardio-renal diseases. Here the authors describe the structure and property driven lead generation and optimization, which resulted in identification of MR modulators (S)-1 and (S)-33. Both compounds were partial MRAs but still demonstrated equally efficacious organ protection as eplerenone after four weeks treatment in uninephrectomized rats on high salt diet and aldosterone infusion. Importantly, and in sharp contrast to eplerenone, this was achieved without substantial changes to the urine Na⁺/K⁺ ratio after acute treatment in rat, which predicts a reduced risk for hyperkalemia. This work led to selection of (S)-1 (AZD9977) as the clin. candidate for treating MR-mediated cardio-renal diseases including CKD and HF. Based on the authors’ findings the authors propose an empirical model for prediction of compounds with low risk of affecting the urinary Na⁺/K⁺ ratio in vivo. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3HPLC of Formula: 638-07-3).

High-throughput screening of protective layers to stabilize the electrolyte-anode interface in solid-state Li-metal batteries was written by Li, Simo;Chen, Zhefeng;Zhang, Wentao;Li, Shunning;Pan, Feng. And the article was included in Nano Energy in 2022.Application In Synthesis of Lithium chloride The following contents are mentioned in the article:

Solid-state Li-metal batteries have attracted growing interest over the years as a promising candidate for next-generation energy storage. Yet, the Li metal not only spontaneously reacts with most solid-state electrolytes (SSEs), but also triggers Li dendrite growth in the SSEs at a lower c.d. than traditional liquid electrolytes. Buffering the electrolyte-anode interface with a protective layer could be a viable solution to this problem. Herein, we search for candidate protective-layer materials from 2316 exptl. known Li-containing compounds using high-throughput first principles calculations Tiered screening of both stability and electronic structure allows the identification of 5, 28 and 7 materials as suitable for protecting Li7La3Zr2O12, Li3PS4 and LiTi2(PO4)3, resp. We demonstrate that electron transfer from Li metal to SSE is successfully blocked by the protective layer to restrain the dendrite growth. This work enables a significant reduction of search space for materials discoveries in protective layer for solid-state Li-metal batteries. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application In Synthesis of Lithium chloride).
